Enterprise AI has a new infrastructure problem: companies are accumulating agents faster than they are developing systems to govern them.Gartner estimates that the average global Fortune 500 company will have more than 150,000 AI agents in use by 2028, up from fewer than 15 in 2025. Yet only 13% of organizations believe they currently have the right AI agent governance in place, according to the research firm.That widening gap is creating a market for infrastructure that sits above individual models and agents — handling execution, permissions, observability, memory, access to enterprise systems and lifecycle management without forcing developers to reconstruct those services for every new agent.xpander.ai, a startup founded by three former AWS principal engineers, is the latest company trying to own that layer.The company is making its enterprise AI agent platform generally available today, positioning it as a vendor-neutral control plane for building, running and governing agents across different models, agent frameworks and infrastructure environments.In an exclusive interview with VentureBeat, xpander.ai CEO and co-founder David Twizer said the company increasingly hears three problems from enterprise customers: agents running locally without centralized governance, agent workflows remaining isolated to individual users, and infrastructure becoming tied to a single AI provider.“The third issue is the most critical part: it’s being locked into one vendor,” Twizer told VentureBeat. “Everything that you do is actually owned by the company that you chose to work with — their tools, their roadmap, their political view of how agents should react to everything that you do.”The caveat is that xpander’s vendor neutrality does not eliminate dependency; it moves the dependency up the stack. Enterprises can swap models, frameworks and infrastructure underneath xpander, but xpander’s proprietary Universal Harness and control plane become the layer coordinating execution, governance, identity, memory and auditability.That could create a new form of lock-in if those configurations and operational state are difficult to migrate to another control plane. xpander’s public documentation does not yet explain how portable that layer is if a customer terminates its enterprise license.The company is also announcing a $7.5 million seed round led by Pico Venture Partners, with participation from Emerge Ventures, Samsung Next and SeedIL.But xpander is entering a market that has evolved considerably beyond a simple divide between proprietary hyperscaler platforms and neutral alternatives.The battle is shifting above the modelModel portability is becoming increasingly common in agent infrastructure.LangChain’s LangSmith Deployment, for example, provides infrastructure for deploying and governing production agents. Enterprises can run its control plane and agent servers entirely inside their own Kubernetes infrastructure, including for air-gapped and data-residency-sensitive environments. LangChain also offers hybrid deployments in which the customer operates agent servers while LangChain manages the control plane.CrewAI is moving in much the same direction. Its enterprise offering includes centralized governance, SSO, role-based access controls, workload identity and policies, while supporting deployment in CrewAI’s cloud, a customer’s VPC or customer-owned infrastructure. CrewAI says its platform can work across models and clouds and lets customers retain and modify the code generated for their agents.Temporal approaches the problem from another direction. Rather than offering an end-to-end agent management environment, it provides durable execution for long-running AI workflows, including crash recovery, retries, human approvals and state that can persist through failures. Its AI platform can orchestrate workflows across different models, tools and systems.Meanwhile, the model and cloud vendors themselves are expanding upward into this infrastructure layer. OpenAI’s Frontier platform provides shared enterprise context, permissions, agent execution and management, while Google’s Gemini Enterprise Agent Platform combines managed runtime infrastructure with agent identity, centralized governance, memory, tracing and policy enforcement around agent-to-agent and agent-to-tool interactions.In other words, xpander’s differentiator cannot simply be that enterprises can run agents outside one model provider’s cloud. Several competitors already offer versions of that flexibility.Its bigger bet is that enterprises will want a framework-independent control plane sitting above an increasingly heterogeneous collection of models, agent frameworks and employee-facing AI interfaces.Twizer’s argument draws partly on his seven years at AWS, where he watched enterprises wrestle with a previous generation of infrastructure lock-in.“Our strategy was to bring the great thing called cloud computing and then try to create solutions that are serverless and, by definition, create vendor lock-in,” Twizer told VentureBeat. But, he said, enterprises ultimately demanded the ability to move workloads among providers.“I think AI is no different,” he said. “Multi-cloud, multi-vendor is a must-have strategy.”A runtime intended to survive model churnAt the center of xpander’s platform is what it calls a Universal Harness — a model-, framework- and cloud-agnostic runtime for executing agents as portable enterprise workloads.Companies can use xpander’s hosted environment or, under its enterprise offering, self-deploy on Kubernetes or on-premises infrastructure. The company also explicitly lists AWS, Google Cloud, Microsoft Azure, private VPCs and fully air-gapped on-premises environments as supported deployment targets.The framework claim is similarly broad: xpander says customers can bring agents built with frameworks including LangChain, Strands and Agno, as well as their existing prompts, rules and skills. It supports proprietary, open-weight and customer fine-tuned models.For developers, xpander exposes three main integration routes: a language-agnostic REST API for control-plane operations, a Python SDK for building agents and workflows, and Model Context Protocol support that exposes agents and tools to MCP clients such as Claude Desktop and Cursor. The REST interface includes operations for managing and invoking agents, tasks and knowledge bases, while the SDK adds event handling and agent lifecycle abstractions.“Think like a Kubernetes environment that runs inside your own premises, your private cloud or our xpander cloud,” Twizer told VentureBeat. “The harness that is agnostic can run any agent of any vendor.”Twizer said the goal is eventually to make model selection more analogous to choosing compute underneath an application than committing an organization to an entire software ecosystem.“You can go from Claude to ChatGPT to Kimi and to your own fine-tuned models,” he said. “All of them will be used in the same way that you use CPUs. You don’t really care who makes them. You just want your application running.”That architecture is intended to let the underlying workloads change while the orchestration and operational layer remains relatively stable.The distinction could become more important as enterprises use more than one AI supplier. OpenAI itself says enterprise AI is shifting from assistance toward delegated work performed by agents, with its latest enterprise data showing rapidly growing agentic usage across functions including legal, sales, recruiting and marketing.At the same time, Google is adding centralized agent governance, identity and gateway controls specifically to manage interactions between agents and tools at scale. Those investments from much larger vendors reinforce xpander’s basic premise: managing the model is increasingly only one part of putting agents into production.What ‘governance’ means in practiceTwizer argues that locally running agents make that operational problem particularly acute.“You install Claude or ChatGPT or Codex or any other AI system that runs on the employee laptop, and you get a black box,” he told VentureBeat. “Nothing is governed, nothing is audited, and nothing is controlled.”His concern is not simply that an agent can access local resources, but that AI products have rapidly moved from generating text to taking actions without enterprises necessarily building equivalent governance infrastructure around them.“It happened overnight that the shift from, ‘Here is the chatbot that helps me write an email,’ became, ‘It is an AI agent that can control my machine and perform API calls,’” Twizer said.xpander’s documentation provides a more concrete definition of what the company means by moving that activity into a governed environment.The control plane can define who is allowed to run an agent, which resources the agent can reach and which actions require human approval. xpander says agents receive named identities and actions can be traced back to the human who invoked them. Tool calls, runs, traces, approvals and failures are logged, with spending attributable at the task level.One particularly relevant architectural detail for security teams is credential handling. xpander says credentials are injected from a vault when a tool call executes, rather than being exposed directly to the model.The company says it is SOC 2 Type II certified and GDPR compliant. Its enterprise tier also includes SSO and OIDC, a private model gateway and sub-organizations with per-team usage attribution.Where xpander is trying to separate itself from products such as LangSmith and CrewAI is in treating the underlying agent framework itself as another replaceable component rather than making its own framework the primary development environment.The company says its runtime can operate xpander-native agents alongside custom agents built with other frameworks. That broader framework neutrality is a company claim and will need to prove itself in production; the overlap among these platforms is already substantial.The cost of building the agent layer yourselfFor enterprises that want centralized control without adopting another vendor’s infrastructure, the alternative is increasingly to assemble many of these components themselves.Twizer argues that this is where the hidden cost of production agents emerges. Accessing a foundation model is comparatively straightforward; recreating the operational infrastructure surrounding a sophisticated managed agent is not.“If you want to do something like the amazing [Anthropic] Claude Code in a way that is governed and secure, you need to build the entire harness,” Twizer told VentureBeat. “You need to build the sandbox and the authentication and the human in the loop and the storage and the session management and the memory layer.”“It’s like investing two years of infrastructure just to run that agent in a secure way,” he added.The company’s documentation says its harness handles long-horizon and multi-tool tasks, sandboxed code execution, persistent memory and recovery when tasks fail or drift. That is important context for Twizer’s argument: xpander isn’t merely offering a gateway that swaps one model API for another; it is attempting to package many of the runtime services enterprises otherwise have to operate alongside those APIs.Twizer said xpander has heard from government organizations and financial institutions using its technology in production that this infrastructure burden was preventing them from deploying agents in a controlled way. The company’s website separately displays logos for organizations including Lenovo, Intel, Workday, Siemens, Nvidia, Intuit, SAP, PagerDuty, Mozilla and Salesforce under the label “Used by teams at.”The company’s answer is not that enterprises should abandon products from Anthropic, OpenAI or other AI providers. Twizer instead argues that companies should retain those models while moving permissions, monitoring and execution into an infrastructure layer they control.“It’s not, ‘Don’t use Claude,’” he said. “It’s actually, ‘Use Claude, but in a way that you watch it, that you secure it, that you monitor it,’” with controls over authorized skills and who can access particular resources.Making agents organizational rather than personalxpander is also adding a collaboration layer it calls Multiplayer AI.The premise is that enterprise agents increasingly need to outlive a single user’s chat session. A workflow might involve an agent collecting data, another system taking an action, an employee approving it and a different team resuming the process hours or days later.Twizer argues that locally deployed assistants have another disadvantage: the expertise employees accumulate through their agents — prompts, skills, workflows and context — tends to stay with those individuals.“You’re making the AI agents better, and you’re not making the company better,” he told VentureBeat. “All the data, all the prompts, all the workflows, all the skills that you are now investing in that ecosystem are being locked inside that vendor, and it’s very hard to share it with other colleagues.”More complex enterprise work also rarely maps neatly onto a single chat session.“Work is not single player. It’s multiplayer,” Twizer said. “It’s happening over the period of multiple days, even weeks. Workflows that are significant to enterprises are not chatbots.”xpander’s shared conversations are designed to keep those interactions in persistent, permission-scoped threads. An agent can be published once for use across an organization, while employees can interact with agents through Slack, Teams, ChatGPT, Claude and xpander’s own interface.The company’s documentation says downstream actions can identify as the human who invoked the agent through end-to-end authentication using OIDC — a potentially important distinction for organizations that need to preserve user-level identity and authorization as work moves through an agent.The requirement for persistent execution is not unique to xpander. Temporal has made long-running, failure-resistant workflows the core of its AI pitch, while LangSmith supports persistent agent deployment and production observability.What xpander is attempting to combine is that runtime infrastructure with enterprise collaboration and governance into a single, portable, flexible, vendor-neutral control plane.Omni tests the harness thesisThe company is also making Omni, its prebuilt agent, generally available.Calling Omni simply a general-purpose agent understates what xpander is now selling. Its documentation describes Omni as an AI forward-deployed engineer that turns a requested business outcome into what the company calls an “Agentic Application”: a backend agent coupled with a frontend experience that can include chat, interactive UI components, reports, dashboards and visualizations.A user can describe the desired outcome, after which Omni is designed to help construct the application, connect its model, skills, tools and data, execute work as tracked tasks, and maintain files and reusable context in an Agent Workspace. The resulting application can then be shared with teammates.For example, xpander’s documentation shows a user asking Omni to build a Redshift Analyzer. Omni is intended to gather the requirements, design the interface, construct the backend agent, attach appropriate connectors and tools, and generate the first live application surface.The documentation also lists Slack, WhatsApp, Telegram and email as Omni channels, while xpander’s broader platform materials list Teams, Claude, ChatGPT, API, webhook, CLI and MCP among the ways work can reach agents. Because the company’s materials describe slightly different channel sets for Omni and the broader platform, enterprises should verify support for their particular interface and deployment configuration.
Omni can also function alongside desktop AI products rather than replacing them. Twizer said employees can continue using their preferred desktop agents while Omni acts as a skill exposing only enterprise-approved data and connectors. When background execution is needed, Omni can create a centrally controlled agent to perform the work.xpander says Omni scored 90.9% on the GAIA benchmark, including strong performance on its most difficult tasks. The result is company-reported and should be viewed as evidence for xpander’s broader thesis rather than independent validation of the platform.Twizer said the company deliberately tested the harness with a mixture of models rather than optimizing around a single proprietary system.“We took Opus, we took Sonnet, we took Kimi, we took GPT, and on that benchmark we got a 90.9% score,” he told VentureBeat.For Twizer, the result supports an argument that agent performance increasingly depends on the infrastructure surrounding the foundation model.“It just proves that the value is in the harness layer and not in the model layer,” he said. “The value is in: How do you handle long-running tasks? How do you handle tool calling? How do you do sandboxing? How do you focus? How do you make the agents focused on the task?”The benchmark results are publicly available, allowing others to examine the company’s methodology, but the broader conclusion remains xpander’s interpretation of its own results.That thesis is increasingly shared across the industry. The disagreement is over who should control that layer.OpenAI and Google are turning it into part of broader AI platforms. LangChain and CrewAI are extending their development ecosystems into enterprise runtimes. Temporal is attacking the execution problem as infrastructure.xpander is betting enterprises will instead want that control plane to remain independent of all three choices: model, cloud and agent framework.The company now has to demonstrate that the extra abstraction is valuable enough to justify another platform in an enterprise AI stack that is already becoming crowded.Pricing and Availabilityxpander’s platform and Omni are generally available now, with two substantially different commercial models for teams using xpander’s hosted service and enterprises running the platform on their own infrastructure.The self-service Team offering has no seat charge and is priced in credits based on agent activity. xpander defines one credit as one cent, meaning $100 buys 10,000 credits. Each event or message that wakes an agent costs one credit for the entire turn, regardless of how long the turn runs, and each tool or API call costs another credit. Model tokens are billed separately in credits at configured rates for the selected model.That makes the cost structure more granular than Twizer’s description of paying for agent “output” might suggest. Long-running execution itself does not appear to create a duration-based charge under the published pricing, but a workflow can accumulate costs through repeated invocations, tool calls and model-token consumption.New accounts receive 1,000 free credits rather than a time-limited free trial, and customers can sign up with a credit card. The Team tier permits unlimited agents, workflows and seats, according to xpander.Model usage can represent a significant portion of total cost, and the company publishes examples intended to make that expense calculable. Its pricing page lists different input and output token rates for individual models and says those model charges are incorporated into the credit system, eliminating a separate model-provider bill for hosted customers. Actual spending therefore depends heavily on the models selected, token volumes and number of tool calls.Enterprises that self-host get a different arrangement. xpander’s Enterprise plan is an annual license starting at 50 agents and supports deployment on a customer’s Kubernetes infrastructure or on-premises environment. It includes SSO and OIDC, sub-organizations with pooled credits and per-team usage reporting, private model-gateway connectivity, onboarding and Tier 1 support. Customers can also bring their own model API keys and use their own negotiated model-provider rates.xpander does not publish the dollar price of that annual enterprise license, so prospective customers cannot calculate the total cost of a private or air-gapped deployment from public information alone. The pricing materials also do not provide a public dollar figure for the 50-agent starting commitment. Those deployments require contacting xpander for custom pricing.“You pay only for the work that the agent is doing,” Twizer told VentureBeat of the hosted model. “No subscription fee, no seat fee, no builder seat, nothing. You just pay for the actual output of the agents.”For enterprise buyers, that distinction is important: xpander’s no-seat-fee claim applies most straightforwardly to its usage-based hosted offering. Organizations that need to own the deployment environment are instead evaluating an undisclosed annual license, infrastructure costs and their own model-provider spend.That leaves xpander with a straightforward but increasingly contested pitch as enterprises confront agent sprawl: keep using whichever models, frameworks and interfaces employees find useful, but move the infrastructure controlling what those agents can do into a common layer the organization can govern.Whether enterprises ultimately want that layer from an independent startup, an agent framework company or the same hyperscalers and model providers xpander wants to abstract away is now becoming another battleground in the enterprise AI stack.How xpander compares with other agent infrastructureThe overlap becomes clearer when the products are compared directly. Several rivals now support multiple model providers, customer-controlled infrastructure or both. The differences increasingly concern how much of the agent stack each platform attempts to own — and whether it provides an agent development framework, a neutral runtime, durable workflow infrastructure or a collection of managed cloud services.SolutionDeploymentModel / framework flexibilityEnterprise and runtime featuresPublic pricingxpander.aiHosted service, plus an enterprise license for self-deployment on Kubernetes or on-premises infrastructure; xpander also advertises private VPC and air-gapped deployments.xpander says its Universal Harness supports multiple models and outside frameworks including LangChain, Strands and Agno.Central permissions and approvals, per-user identity, audit trails, tool-call logging, credential injection, long-running tasks, shared “Multiplayer” workflows and Omni. The company says each action can be associated with the invoking human.Hosted service is usage based: 1 credit = $0.01, with 1 credit per agent wake and 1 per tool/API call, plus model-token charges. New accounts receive 1,000 credits and seats are unlimited. Enterprise is custom-priced, annual and starts at 50 agents.LangSmithCloud, hybrid or fully self-hosted on Docker Compose or Kubernetes; hybrid and self-hosted options require Enterprise.LangChain describes LangSmith as a framework-agnostic platform for observing, evaluating and deploying agents.Observability, evaluations and agent deployment; Enterprise adds SSO, ABAC/RBAC and self-hosted or hybrid deployment.Plus is $39 per seat per month, then pay-as-you-go. Enterprise is custom priced plus usage charges.CrewAISaaS, customer VPC or customer-owned infrastructure.CrewAI centers on its own agents, crews and flows framework, but supports multiple LLM providers, including custom model integrations.Agent building and orchestration, long-running flows, memory, observability and human-in-the-loop controls. Enterprise adds SSO, RBAC, workload identity, PII redaction and policies.A free tier is available; Enterprise pricing is custom and includes a 45-day onboarding program.TemporalTemporal Cloud or the self-hosted open-source Temporal Service. Application workers continue to run in the customer’s environment when using Temporal Cloud.Not an agent framework or model gateway. Temporal is model-agnostic because it provides durable workflow execution underneath application and agent code rather than selecting the model or agent framework.Durable execution, persistent workflow state, retries, timers, signals and recovery — useful for agents that must survive failures or run for long periods. Cloud tiers add audit logging, roles and higher-tier SSO/SCIM.Temporal Cloud Essentials starts at $100/month with 1 million Actions, 1 GB active storage and 40 GB retained storage. Business starts at $500/month; Enterprise is custom. Additional Actions start at $50 per million before volume discounts.Amazon Bedrock AgentCoreFully managed AWS infrastructure rather than a customer-operated control plane.AgentCore Runtime explicitly supports agents built with outside frameworks and custom code, as well as foundation models inside or outside Amazon Bedrock.Managed runtime isolation and scaling plus optional identity, memory, gateway, browser, code interpreter, observability and evaluation services. The runtime supplies infrastructure while developers retain their own orchestration loop.Consumption based. Runtime currently lists $0.0895 per vCPU-hour and $0.00945 per GB-hour, with separate charges for services such as memory, gateway, web search and evaluations.The comparison complicates a simple vendor-neutrality pitch. AWS AgentCore, for example, supports models outside Bedrock and frameworks including LangGraph, CrewAI and Google’s ADK, while LangSmith explicitly calls itself framework agnostic. CrewAI offers customer-controlled deployments and broad model choice. Temporal lets companies self-host the durable execution layer entirely, although it solves a narrower infrastructure problem rather than offering a complete agent control plane.That makes xpander’s potential differentiation more specific. It is trying to combine framework and model portability with enterprise identity, governance, runtime infrastructure and an employee-facing collaboration layer, rather than competing only on the ability to swap models or deploy outside a vendor’s SaaS environment. xpander also prices its hosted platform around individual agent wakes and tool calls rather than seats, although enterprises requiring self-hosting face an undisclosed annual license beginning at 50 agents.

Presented by MongoDBBuilding AI that is accurate, secure, and reliable is a major engineering feat for organizations subject to the compliance obligations that govern healthcare, financial services, and transportation. The challenge of delivering AI-driven products is compounded by the fact that technology in these industries has tended to lag behind other sectors because regulation requires organizations to move carefully — and slowly. Now, many are also confronting data infrastructure modernization projects as they try to catch up with today’s demand for AI.Australian-founded AI Care Partner Heidi offers an example of successful modernization. Its flagship product, Heidi Scribe, now automates much of the administrative work that consumes clinicians’ days across more than 190 countries, supporting roughly 2.7 million patient interactions each week. That expansion rests on infrastructure decisions taken years before the company reached global scale, says Yu Liu, co-founder and chief technology officer at Heidi.“In most industries, an AI feature that is wrong two percent of the time registers as an inconvenience, while in healthcare that same error rate becomes a clinical safety issue,” says Liu. “The architecture has to be built around the assumption that every output may be scrutinised, audited, and relied upon in a patient’s care.”Why deploying production AI in healthcare is architecturally differentFor Heidi, data residency is a precondition rather than a feature. A clinician in Sydney, London, Tokyo, or Denver is operating under different regulatory regimes, including the Australian Privacy Principles, GDPR, APPI, and HIPAA, and their patients’ data has to live in-region.Heidi runs fully logically isolated production deployments across the world, so residency is enforced by architecture. Auditability also has to be built in from day one, because an organization needs to be able to answer what the model saw, what it produced, and what the clinician changed, for any session, months later, when called upon.“The blast radius of change must be engineered down,” Liu says. “In less regulated industries you can ship fast and fix forward, but in healthcare we invest heavily in making change safe by default, with continuous integration gates on risky change classes, canary releases, and treating even database schema and index changes as code that goes through review. Our speed is a product of that safety rather than something we achieve in spite of it.”Choosing a database to connect with AI workflowsHeidi handles a diverse set of medical data collected from multiple sources, including forms, referrals, and clinicians’ notes, all of which had to be consolidated into one consistent format and one location to connect seamlessly with AI workflows. Rigid rows and columns would have been ill-suited to that workload.For Heidi, those requirements made a document database the natural choice.MongoDBgave the team the flexibility to accommodate rapidly changing AI data without constantly reshaping the underlying database.“The model is maybe 20% of the system, and the data architecture is what determines whether the other 80% holds up under real clinical load,” Liu says.An AI Scribe session isn’t a single piece of data. It’s a collection of transcripts, structured notes, templates, documents, patient context, EHR integration state, and dozens of other related artifacts that change from week to week. MongoDB lets a session’s data live together in shapes that match how clinicians actually work, and lets Heidi evolve those shapes without a migration freeze every time the product moves.”MongoDB Atlas stood out because it combined the power of the document model, which allows seamless scale, flexibility, and high performance, with built-in AI-ready features such as MongoDB Vector Search,” Liu says. “This means that Heidi does not need another bolt-on vector database to augment its existing platform.”With more than 130 cloud regions globally alongside on-premises and hybrid options, MongoDB Atlas is the most widely available, globally distributed database platform, and its unified query API lets developers build full-text search, real-time analytics, and event-driven experiences without complicating their architecture.”Heidi Scribe converts large volumes of medical documents into vector embeddings via LangChain in Atlas, enabling semantic search that connects transcribed medical terms directly to corresponding external knowledge,” Liu adds. “Migrating to Atlas reduced latency on key APIs by nearly 33%.”What a trustworthy clinical RAG system requires“Retrieval is a data architecture problem before it is an AI problem,” Liu says. “In consumer RAG, you retrieve from the open web and hope, whereas in healthcare what you retrieve from is the compliance surface.”Heidi Evidence retrieves from licensed clinical knowledge bases, including partners like BMJ Best Practice, NICE CKS, and MIMS, and it is jurisdiction-aware, so a U.K. clinician gets U.K. guidance and an Australian clinician gets Australian formularies, because the right answer in one country can be the wrong answer in another.Heidi’s embeddings and vector indexes live in MongoDB Vector Search, inside the same regionally isolated deployments as the rest of its data, which means retrieval physically cannot cross a residency boundary, and they are not operating a separate vector database with its own security and compliance story. Citations are a hard contract rather than a prompt suggestion, because the model only ever sees retrieved chunks that are already bound to source records.Regional isolation enables global compliance and scale“Each region is a full, isolated production deployment with its own MongoDB Atlas clusters, its own compute, and its own key,” Liu says.“That is what lets us walk into a U.S. health system, an NHS trust, or an Australian hospital group and give a clean answer on residency, because it is enforced by infrastructure rather than promised by contract,” he explains. “Running multiple isolated regions with a lean team only works because the database layer is managed and consistent. We are also multi-cloud, meaning a new region can stand up another deployment on rails we have already built.”That architecture has been most visible in the U.S., where Beth Israel Lahey Health, one of New England’s largest health systems, rolled out Heidi’s AI scribe following a pilot finding 74% of clinicians reported reduced after-hours documentation (“pajama time”), and where non-profit system MaineGeneral Health selected Heidi as a strategic partner in its rural healthcare work.“Entering the U.S. market meant standing up another region on rails we had already built rather than re-engineering for HIPAA after the fact,” Liu says.Lessons learned and the roadmap ahead”Re-partitioning a large, hot, always-on collection is a serious engineering program, whereas choosing a shard key on day one is a design meeting,” Liu says. “We are doing that work now in partnership with MongoDB, but the lesson for anyone building a data-heavy AI product is that horizontal scale for your fastest-growing data is a founding decision, just like residency.”Heidi is now extending beyond the consult note to support the full clinical workflow, from pre-visit context to post-visit documents, referrals, and workflow automation. The company is also exploring how MongoDB, large language models, and its own tooling can power an agentic ecosystem for clinical workflows.“In healthcare AI, reliability engineering is trust engineering,” Liu says. “A clinician’s trust is lost just as fast by downtime, latency, or a data inconsistency as by a bad note, and some of our highest-leverage work is invisible, including canary releases with automatic rollback, CI gates on database changes, and cross-region consistency checks. Clinician trust is the product, and trust is architectural.”Sponsored articles are content produced by a company that is either paying for the post or has a business relationship with VentureBeat, and they’re always clearly marked.

Most teams building retrieval augmented generation (RAG) systems for high stakes classification make the same architectural bet: Route every ambiguous case straight to the language model and trust the retrieved context to sort it out. This works fine in a demo. It falls apart the moment the system has to survive an audit, a regulator, or a compliance officer asking why a specific decision was made six months ago.I have spent the last year building RAG based classification systems in regulated enterprise settings, where the cost of a wrong answer is not a bad chatbot reply. A decision has to hold up to scrutiny long after the model produced it. This environment forces a different design philosophy than most AI engineering content assumes. Here is what changes when you cannot afford to be probabilistic about everything, and how a cascade architecture solves it.The invisible cost of an all LLM pipeline
The appeal of routing everything through a large language model (LLM) is obvious: Fewer moving parts, faster iteration, the model handles unanticipated edge cases. The problem shows up later, in three places.First, auditability. “The model decided based on retrieved context” is not an acceptable answer. You need a decision path a human can reconstruct without rerunning inference and hoping for the same output.Second, cost at scale. If your system processes tens of thousands of cases a day and every one hits an LLM call with several retrieved documents in context, your inference bill and latency both scale with volume in a way that rule based logic does not.Third, and least discussed, model drift on the easy cases. LLMs are excellent at nuanced judgment calls. They are inconsistent, in ways that are hard to detect, on cases that should have a deterministic answer. A clear structured match against known criteria should never depend on a language model’s mood.The cascade approach
The fix: Stop treating the LLM as the front line and start treating it as the escalation path. In practice this means a three stage pipeline.Stage one is deterministic. Exact matches, structured field comparisons, and anything with a clear rule get resolved here with no model call at all. This stage should clear the majority of volume, often more than half depending on your data quality, and every decision is fully explainable because it is a lookup, not an inference.Stage two is where retrieval earns its keep. For cases that survive stage one — and I mean survive as in they were not clearly resolved — you build a retrieval layer that pulls the specific evidence relevant to the ambiguity: Prior reviewer decisions on similar cases, contextual documents that explain an apparent conflict, or historical precedent that clarifies an edge case. The retrieval step matters more than the generation step here. If you retrieve the wrong context, even the best language model in the world will produce a confident, well reasoned, wrong answer.Stage three is the LLM call, and it should only see the residue that stages one and two could not resolve. This is the part people skip when they design their first version, and it is the single biggest lever for both cost and quality. In one system I worked on, routing only the genuinely ambiguous 10 to 15% of cases to the LLM cut inference cost by roughly 6X compared to an all LLM baseline, while improving consistency on the deterministic majority to effectively perfect.Designing the prompt for asymmetric riskOnce a case reaches the LLM stage, most teams default to a neutral prompt: “Assess whether this case should be approved or flagged.” That framing is wrong for high stakes classification because the cost of the two error types is not symmetric. Missing something that genuinely needed attention can mean real harm downstream. Incorrectly flagging something that was fine costs a reviewer’s time and a delay. Those two outcomes are rarely equally bad, yet a neutral prompt asks the model to treat them as if they were.An asymmetric risk prompt makes that tradeoff explicit to the model rather than letting it guess at your risk tolerance. Concretely, this means instructing the model to treat uncertainty as a reason to escalate rather than clear, providing calibrated examples of both error types with their consequences spelled out, and asking for a confidence score alongside the classification rather than a binary answer. The confidence score becomes your second cascade point: Anything below a certain threshold goes to a human reviewer instead of being auto resolved, no matter what the model’s classification says.This sounds like a small prompt engineering detail. In practice it is the difference between a system that reduces reviewer workload and one that quietly increases risk while looking like it is working.Evaluating a system like this properlyStandard RAG evaluation metrics were not built with this use case in mind, and using them without adaptation will give you a false sense of confidence. A few adjustments that matter.Retrieval quality needs to be measured separately from final classification accuracy. A system can have excellent retrieval ranking scores and still make bad final decisions if the generation step misweights the evidence. Track them independently.Your evaluation set needs deliberate oversampling of the cases that reach stage three, since that is where your system’s judgment actually gets tested. If your eval set mirrors your production distribution, it will be dominated by the deterministic cases your cascade already handles well, and you will be blind to exactly the failures that matter most.LLM as judge evaluation works for this domain but only if the judge prompt encodes the same asymmetric risk framing as your production prompt. A judge that treats both error types equally will systematically favor the wrong tradeoff when you are tuning your system.Finally, build a feedback loop from confirmed outcomes back into your retrieval corpus. When a human reviewer overturns a model decision, that case and its correct resolution should become retrievable context for future similar cases. Without this, your system’s handling of ambiguous cases never improves, it just keeps making the same category of mistake at the same rate.The broader lessonThe instinct to reach for the most capable model for every decision is understandable, but in domains where wrong answers have real consequences, the more valuable engineering work is deciding what should never touch the model at all. Cascade architecture is not a workaround for LLM limitations. It is what a mature RAG system looks like once you have actually had to defend its decisions to someone whose job is to find the flaw in your logic.If you are building AI systems for any regulated or high stakes domain, the question worth asking before you write a single prompt is not “How do I get the model to handle this well.” It is “Which parts of this decision should never have been the model’s job in the first place.”Vineet Vijay is a Lead AI and machine learning engineer.

DeepSeek’s V4 Flash has topped model leaderboards and been hailed by developers as a “total monster” since its rollout. But in real-world testing, it completed just 53.8% of a batch of complex agent tasks. Composio ran the model through eight different agent harnesses, including Claude Code, Codex, and OpenCode, on 30 deliberately difficult, multi-step tasks spanning live tools like Gmail, GitHub, Slack, and Google Sheets. Of 240 total runs, 129 passed — and only six of the 30 workflows were completed successfully by every harness tested.The gap illustrates why orchestration, not raw model capability, may decide whether the model succeeds in enterprise settings: the same model produced substantially different results depending on the harness, tool configuration, caching behavior, retries, and provider stack it ran on.DeepSeek said it will be hiking the prices for V4 Flash and Pro, models that have quickly become favorites among developers building coding assistants and agents. While it seems the move might undercut its very appeal — strikingly capable models at ultra-low pricing that frontier providers simply can’t match — it also moves the story beyond the now-clichéd “cheap Chinese model” narrative, as early use cases emerge and enterprises figure out where different models fit into their tech stacks and what workflows they should be aimed at.”Insane” adoption numbers as DeepSeek flips the cost structureDeepSeek rolled out V4 Flash to public beta July 31, and made V4 Pro generally available on August 13. The 284-billion-parameter Flash is built for volume and speed, the 1.6 trillion-parameter Pro for more complex workflows.Both models have flexible reasoning capabilities (low, high, max) and ‘thinking modes’ applying chain-of-thought (CoT) reasoning to improve answer accuracy.Users were immediately impressed by Flash’s capabilities. It has dominated OpenRouter’s usage leaderboard since its rollout, currently the most-used model on the platform by weekly token volume.“The adoption numbers of the initial DeepSeek V4 Flash were insane,” ML researcher Nathan Lambert posted to X, adding that the new version “scored the same as GLM 5.2,” making it a “total monster” that will be used extensively.DeepSeek switching the cost model adds an interesting dimension. V4 API rates are going up by as much as 1,100% depending on the model, token type and time of use. The new pricing structure: Flash will be 22 cents per million input tokens and 66 cents per million output tokens off-peak; and 44 cents per million input tokens and $1.32 per million output tokens at peak. This represents a 57% to 371% increase. Pro will be 66 cents per million input tokens and $1.98 per million output tokens off-peak; and $1.32 per million input tokens and $3.96 per million output tokens at peak. This shows a 51% to 355% jump. Cache hits, meanwhile (when models reuse prompts rather than starting from scratch), are going up between 52% and 1,100%.DeepSeek says offering 50% lower off-peak usage is intended to encourage “more flexible workload scheduling.” Seventeen of every 24 hours stay at half price, and the new structure actually prices the company’s home market the highest.”This is not a simple price rise,” said Sanchit vir Gogia of Greyhound Research. “It is a pricing architecture that makes the timing of inference an economic variable.”Work that can wait — such as batch evaluation, synthetic-data generation, and overnight development runs — moves into the cheap hours; interactive agents and live operations cannot. Gogia said irritation among developers and enterprises is genuine and vocal, and that DeepSeek’s past low pricing doesn’t obligate it to stay cheap forever.At first glance, it does look like a “suicidal move from a platform still looking for credibility against more established AI model vendors,” said tech analyst Carmi Levy. The increases will certainly eat into DeepSeek’s price advantage and force customers to weigh concerns around the company’s Chinese origins more heavily.Still, DeepSeek remains far cheaper by all pricing measures relative to competing models from OpenAI, Anthropic, Google, Cohere, xAI, and others, he said. So, while the move will force DeepSeek to emphasize performance and security over cost, it hardly wipes out its already-notable price-performance advantage, and still gives customers ample wiggle room to justify its use for specific workloads, Levy said. The math will just have to be more tightly calculated. “The advantage will likely erode over time as DeepSeek inevitably continues to align pricing with market realities, but for now it’s still easy to make the business case,” Levy said. Where can DeepSeek Flash fit into enterprise environments? Adoption inside enterprises remains an open question due to cost, capability, reliability, data governance, security, and other factors.One use case is batch processing, Levy said. This kind of work is typically routine and repetitive rather than demanding top-tier intelligence, so it makes sense to use a cheaper, more efficient model. “It’s a high-performance inference engine that enterprises can consider using for point solution workloads rather than as a wholesale replacement for the incumbent offerings,” Levy said. Partial adoption will likely involve isolated, non-sensitive workloads with clearly-defined success metrics, strict oversight, permissions controls, and fallback models in case of failures, he noted. Broader deployment will require DeepSeek and its hosting partners to demonstrate strong reliability, security, privacy, auditability, and deployment options. As it adjusts price structures based on demand, DeepSeek also must retain a large enough price-performance advantage to justify any risk, he said.Expect unsanctioned, smaller-scale use in backroom labs and contained test environments as IT teams get familiar with the new model and figure out when and how to bring it to senior leadership for budget approval.“DeepSeek has built a well-earned reputation as a global disruptor,” he said, “and it’s clear that its march to broader enterprise adoption will continue to gather momentum.”Testing DeepSeek in multi-tool workflows While many use cases are still in the experimental phases, Meta software engineer Naman Ahuja offers one that could translate directly into enterprise environments. In a project unrelated to his employer, he built a home-automation agent with DeepSeek V4 Flash to explore how a lower-cost model performs as the reasoning/orchestration layer for a real multi-tool workflow.When he leaves home, an agent coordinates several actions across otherwise separate systems: Such as setting a thermostat to “away” to reduce unnecessary energy use, arming a Ring security system, closing and locking doors. “What interested me was not simply whether the model could understand a command, but whether it could translate intent into a sequence of actions across multiple tools where reliability matters,” Ahuja said. The biggest lesson was that once a model can take actions, reliability matters as much as intelligence. The system needs structured tool outputs, verification that actions actually succeeded, retry/failure handling, and clear boundaries around what the model is allowed to do.In the case of enterprise, “the architecture is similar.” Home devices change to ticketing systems, databases, CRM platforms, or infrastructure APIs. The most useful agents will likely orchestrate repetitive workflows across multiple systems, with scoped permissions, auditability, observability, and human approval for higher-risk actions.“Many valuable AI agents will not be chatbots; they will be background agents coordinating APIs, infrastructure, and business systems in response to events,” he said. Enterprises need tangible use casesBut Flash’s API is still in public beta, Gogia pointed out, and there is not yet an evidence trail of settled enterprise adoption, real-world deployments, and named customers.“The benchmark story is looser than its retelling, the portfolio story is newer than it looks, and the economics have moved into the system around the model,” he said. Developer mainstreaming is proven; enterprise standardization is not. “The model is mainstream by traffic and still unproven by contract.”DeepSeek’s own integration guidance is an important consideration, he said: Its documentation for at least one popular agent environment states that built-in V4 entries are not sufficient for reliable operation without compatibility overrides. “Which is a vendor telling the market, accurately, that benchmark performance is not a proxy for production readiness,” Gogia said. “A model can score beautifully and still misbehave once tools, credentials, and state enter the room.”The serving layer behaves no differently: the same open weights run by different hosts show visible differences in throughput and uptime. “Choosing Flash therefore answers one procurement question and opens three more: Who serves it, where it runs, and which controls surround it,” Gogia said.Prepare for a multi-model futureDeepSeek offers a nuanced case for a multi-model future. V4 Flash is being deployed as the high-volume worker inside diverse estates, Gogia noted: It handles routine generation, retrieval, and background automation, while more difficult or sensitive tasks go elsewhere. “The question is whether its performance is sufficient for the real-world workflows enterprises actually run, not whether it tops every benchmark,” he said. Enterprises must determine which combination of model, harness, and provider completes the work safely at the lowest cost.Adam Dalloul, CEO and founder of EmpirioLabs AI, pointed out that bigger isn’t always better; workflows should be task-dependent. For example, his team at EmpirioLabs AI — which hosts 100-plus models on one API, including DeepSeek V4 Flash — were recently working on translating its site into different languages, and there was no need for a large model like GPT 5.6 Sol or Opus 5 to complete the task. “This is where subagents come in handy,” he said. His recommended approach: Spawn cheaper subagents and adapt per task. For instance, use Flash variants for day-to-day work, and Pro variants when you need something more powerful. “It depends on the nature of your application.”Many companies are pivoting towards their own internal benchmarks to route models effectively, Dalloul noted. For example, his team has a workflow that puts a model through various gates and instructions. This helps them identify the model with the speed and accuracy required for the task. In another example, one of his enterprise clients exclusively wanted access to DeepSeek V4 Flash. They had tested a variety of models and V4 Flash was the only one that met their criteria for speed, cost, and an “appropriate intelligence threshold.”Meta’s Ahuja agreed that smaller, more efficient models can handle frequent, well-defined agentic tasks, while more expensive frontier models can be reserved for “ambiguous, difficult, or higher-risk decisions.” The relevant metric increasingly becomes cost per successfully completed workflow rather than simply cost per token. The trade-off, however, is that cheap inference does not automatically mean cheap or safe automation, he said. Once an AI system can take actions, reliability, verification, permissions, failure handling, and security become much more important. “A failed text response is inconvenient; a failed action in an operational workflow can have real consequences,” Ahuja said.

There is a step in the development process for large language model (LLM)-assisted tooling that most teams skip because it’s tedious, time-consuming, and doesn’t produce results visible to end users: Verifying that what the model is saying is actually correct. Not fluent, not coherent, not topically relevant — correct in the sense of accurately identifying the right answer to the specific problem the tool was built to solve.The gap between “this output sounds right to me” and “this output is verifiably correct” is where most LLM-assisted enterprise tools fail quietly. They pass internal review because the output sounds right. They fail in production because those people weren’t reviewing against ground truth — they were reviewing against their intuition about what a good answer looks like.This distinction matters more as LLM-assisted tools move from productivity accessories to components that influence real business decisions. If your AI-assisted tool is shaping how an analyst investigates a data quality issue, how a compliance reviewer decides whether to escalate a flagged record, or how an operations team triages a validation failure — the accuracy of its output has real consequences. “Seems reasonable” is not an adequate evaluation standard for that.What qualitative evaluation actually catchesThe standard evaluation approach for LLM output in enterprise tooling is qualitative: A sample of outputs is reviewed by someone with domain knowledge, judged against a mental model of what a good answer looks like, and the prompt is adjusted if too many outputs seem off.This catches a specific class of problems: Outputs that are obviously wrong, poorly formatted, or off-topic. These are real issues worth catching. They’re also the easy ones.What qualitative evaluation consistently misses is the class of outputs that are wrong in ways that are difficult to see without checking against something external. An explanation that confidently identifies the wrong root cause, in language that sounds authoritative, based on reasoning that sounds plausible — this passes qualitative review. It fails the moment someone with the right context checks it against what actually happened.In a system whose value proposition depends on accuracy, “sounds plausible” is not the same as “correct.” The two can diverge significantly, and qualitative review won’t tell you when they have.What an actual eval harness looks likeThe alternative is building an evaluation harness that scores model output against labeled ground truth — a set of cases where the correct answer is known, against which you can measure accuracy rather than coherence.I built this while developing a root-cause explainer for data migration drift: A tool that takes a detected drift event and generates a ranked explanation of what most likely caused it. The first prototype produced fluent, specific-sounding explanations that passed qualitative review. When I tested it against cases where I already knew the root cause, the explanation was wrong often enough to matter.The eval harness I built works in three parts.First, a synthetic ground truth dataset: Cases where the correct answer is known by construction. This meant introducing specific, controlled causes into a test pipeline — schema changes, transformation logic bugs, source system behavioral shifts — recording exactly what I introduced, and running the model against the resulting drift events. The correct answer for each case was the cause I had deliberately introduced.Getting the synthetic scenarios realistic enough to be useful required more care than I expected. Early versions were too clean — the drift signal was obvious in ways that real production drift events aren’t. Adding realistic noise, overlapping signals, and cases where multiple plausible causes were present simultaneously was what made the synthetic set actually predictive of real-world performance.Second, a scoring function that evaluates ranked output. Binary correct/incorrect isn’t sufficient when the model produces a ranked list of likely causes rather than a single answer. An explanation that correctly identifies the root cause as the third most likely candidate is meaningfully different from one that identifies it as the most likely. The scoring function evaluated two dimensions: Presence — did the correct answer appear in the output at all — and rank — how prominently was it featured relative to incorrect candidates. These were combined into a weighted score that rewarded both finding the right answer and ranking it appropriately.Third, systematic evaluation across the full synthetic dataset rather than spot-checking. Running the harness across the complete set reveals patterns that spot-checking misses: Which categories of problem the model handles reliably, which it consistently gets wrong, and which combinations of signals produce the highest rate of confident incorrect explanations.What the evaluation revealedThe results were more informative than any qualitative review could have been.Schema change scenarios scored well — the model was reliable at identifying upstream schema changes when the evidence was present and distinctive. Transformation logic bugs were harder — the model consistently identified the right general category but misattributed the specific change that caused the problem, particularly when multiple changes had been made close together. Overlapping-signal scenarios were the hardest — cases where two different causes occurred close in time produced the highest rate of confidently wrong explanations.That last finding is the one that qualitative review would never have surfaced. The model’s expressed confidence didn’t correlate with its accuracy — it was most confident in the cases where it was most wrong. Without the eval harness measuring against ground truth, that pattern would have been invisible.The practical implication for enterprise AI deploymentFor teams deploying LLM-assisted tools in enterprise contexts — particularly tools that influence how people investigate problems, triage alerts, or make routing decisions — the eval harness question to answer before production deployment is: Have we measured accuracy against cases where we know the right answer, or have we only reviewed whether the outputs seem reasonable?If the answer is the latter, the tool has been tested for fluency and coherence but not for correctness. Those are different properties. For tools that shape business decisions, correctness is the one that matters.Building the synthetic ground truth dataset is the hard part and the part most worth investing in. It forces you to define precisely what “correct” means for your specific use case — which turns out to be a useful exercise independent of the evaluation itself. The scoring function and the harness infrastructure are relatively straightforward once you have that definition. Without it, you’re measuring something other than what you’re trying to guarantee.Arun Mishra is an enterprise architect.

Chinese AI startup Z.ai, known internationally for its growing lineup of powerful, largely open source GLM series of language models, today released GLM-5.3 with substantial gains in long-horizon coding and a more consequential — and potentially sensitive — jump in cybersecurity capabilities.Already, GLM-5.3’s cyber capabilities have found a “potentially serious vulnerability in Cursor,” the AI coding startup recently acquired by SpaceX, according to z.ai developer advocate Lou, posting on X. VentureBeat also tagged Cursor for confirmation on X and is awaiting response.GLM-5.3 is available initially only through the company’s GLM Coding Plan and ZCode coding environment, while API access and open weights are coming later, “once safety evaluation and hardening are complete,” according to the company. Z.ai says it plans to release weights approximately two weeks after launch.For enterprise developers, the notable part of the release is not simply another round of benchmark improvements. Z.ai says GLM-5.3 uses the same base model as GLM-5.2, with the improvements coming entirely from scaling post-training across more environments, more diverse tasks and additional reinforcement-learning compute.That makes GLM-5.3 something of a test of how far a frontier-scale base model can be pushed without another expensive pretraining cycle.“Scaling post-training is all we did for GLM-5.3,” Z.ai wrote in its technical announcement.The results suggest considerable headroom. But they have also produced an unusual problem for an open-model developer: according to Z.ai, cybersecurity capabilities improved faster than anticipated as training scaled, particularly as tasks progressed from vulnerability identification toward constructing complete exploitation chains.Reuters reported Friday that Z.ai is also introducing controls around some of the model’s more advanced capabilities, including a “trusted access” approach for sensitive functionality.A large jump in coding without another base modelGLM-5.3 builds on the 743-billion-parameter-scale base model behind GLM-5.2 rather than replacing it. Z.ai instead expanded the post-training system it had already assembled around long-horizon reinforcement learning.Those environments increasingly resemble complete engineering jobs rather than isolated programming exercises.Z.ai describes scenarios in which an agent receives access to codebases, documentation, compute clusters, storage systems and experimental results, then has to diagnose problems, modify systems, run experiments and demonstrate a measurable improvement while preserving correctness. Some tasks are designed to approximate several days of work for an experienced engineer.The approach produced sizable generation-over-generation improvements on Z.ai’s reported evaluations.GLM-5.3 jumps from 4.6 to 28.3 on Terminal-Bench 3.0, from 46.2 to 66.9 on DeepSWE v1.1, and from 26.2 to 48.2 on AutomationBench. On Agents’ Last Exam CLI, it improves from 23.8 to 28.5.The model does not dominate every frontier competitor. Z.ai’s own benchmark table shows GPT-5.6 Sol at 34.6 and Claude Fable 5 at 33.7 on Terminal-Bench 3.0, compared with GLM-5.3’s 28.3. On DeepSWE v1.1, GLM-5.3 scores 66.9, compared with 72.7 for GPT-5.6 Sol and 69.7 for Fable 5.But Z.ai is also emphasizing efficiency rather than benchmark position alone.On its private Z.ai Code Bench, GLM-5.3 reaches a 34.5% result at its Max reasoning setting while consuming roughly 75,000 output tokens per task. GLM-5.2 reaches 23.4% while consuming approximately 96,000. At High effort, GLM-5.3 reaches 31.4% at roughly 50,000 output tokens, compared with Z.ai’s reported 29.5% for Claude Opus 4.8 using 120,000.Because Code Bench is Z.ai’s own private evaluation, those comparisons should be treated as company-reported results rather than independent measurements. Still, reducing token consumption while improving task completion is operationally important for enterprises deploying coding agents, where long-running loops can make inference cost and latency compound quickly.Cyber capabilities developed faster than Z.ai expectedThe more unusual development is cybersecurity.Z.ai introduced vulnerability-discovery environments into GLM-5.3’s post-training mix expecting the model to improve at finding software flaws. Instead, the company says capability began progressing further along the exploitation chain.“As we scaled post-training, cyber capability developed faster than we expected,” Z.ai wrote.On CyberGym, which tests vulnerability discovery and validation against source code, GLM-5.3 scores 84.5%, compared with 77.2% for GLM-5.2. That also edges Z.ai’s reported scores for GPT-5.6 Sol at 83.6% and Mythos 5 at 83.8%.The advantage does not extend across the entire exploitation stack. GLM-5.3 scores 54.4% on ExploitBench, more than twice GLM-5.2’s 24.4%, but remains well behind the 76.5% Z.ai reports for GPT-5.6 Sol and 78% for Mythos 5.Similarly, on ExploitGym, GLM-5.3 completes 105 tasks under a normalized two-hour budget and 130 under six hours, up from 29 and 39 for GLM-5.2. Fable 5 reaches 181 and 247, while GPT-5.6 Sol reaches 216 and 293.The direction of travel may matter more than the leaderboard position.Z.ai says work with security teams in China has resulted in 2,436 vulnerability findings across 269 projects after expert review, screening and deduplication. Its disclosure ledger lists 1,097 as critical or high severity, with 53 publicly disclosed and 2,383 still under embargo at the time of the release.That creates a tension increasingly facing frontier model providers: the same long-horizon agent capabilities that make models more useful for software engineering can also make them more capable security researchers — and potentially more capable offensive operators.GLM-5.3 also requires developers to change how they call the modelDevelopers migrating existing GLM applications should pay attention to a breaking API behavior.GLM-5.3 supports three reasoning-effort levels — low, high and max — with max the default and Z.ai’s recommended setting for coding. But unlike previous releases, thinking cannot be disabled.Applications currently sending thinking.type: “disabled” must change the value to enabled and specify a reasoning effort before switching the model identifier to GLM-5.3. Otherwise, Z.ai says the request will fail.That makes GLM-5.3 an actual migration rather than simply a model-name substitution for some production applications.From GLM-4.5 to GLM-5.3: Z.ai’s rapid push into agentic engineeringGLM-5.3 is the latest step in a rapid shift by Z.ai — formerly known as Zhipu AI — toward coding agents and long-running autonomous engineering workloads.GLM-4.5, released in July 2025, established much of that direction. The 355-billion-parameter mixture-of-experts model was designed to combine reasoning, coding and agent capabilities, while the smaller GLM-4.5-Air offered 106 billion total parameters. Z.ai released the models with open weights and emphasized integration with agent frameworks.GLM-4.6 followed in September, expanding context from 128,000 to 200,000 tokens and targeting coding, tool use and agent workflows in environments including Claude Code, Cline, Roo Code and Kilo Code. Z.ai also began placing greater emphasis on token efficiency in real-world coding evaluations rather than benchmark performance alone.The larger architectural jump came with GLM-5 in February 2026. Z.ai scaled the model from GLM-4.5’s 355 billion parameters to 744 billion, with 40 billion active parameters, and increased pretraining data to 28.5 trillion tokens. It also introduced its “slime” asynchronous reinforcement-learning infrastructure and explicitly repositioned the GLM family around “agentic engineering” and long-horizon tasks.By June, GLM-5.2 had turned that strategy into a more direct enterprise proposition. The 753-billion-parameter model arrived with a stable 1-million-token context window, open weights under an MIT license and support across more than 20 coding environments. It also introduced IndexShare, which reuses an indexer across sparse-attention layers to reduce the computational burden of very long contexts.GLM-5.2 was priced at $1.40 per million API input tokens and $4.40 per million output tokens, with cached input priced substantially lower, positioning Z.ai as both a technical and pricing competitor to proprietary frontier labs.Z.ai’s ambitions have been expanding outside model development as well. Reuters reported last month that Zhipu AI raised roughly HK$31.4 billion, or about $4 billion, through a Hong Kong share sale, with proceeds intended for areas including research and development, computing infrastructure, talent and business expansion.Taken together, the releases show a consistent progression: GLM-4.5 unified reasoning, coding and agents; GLM-5 substantially scaled the foundation model; GLM-5.2 attacked long-context and long-horizon engineering; and GLM-5.3 is now attempting to extract substantially more capability from that same foundation through post-training.Pricing, ZCode and availabilityGLM-5.3 is available now through Z.ai’s GLM Coding Plan and ZCode.ZCode is the company’s own coding-agent environment and supports long-running “Goal” tasks that plan, implement, test and verify work. It also offers remote control of running tasks and is available on macOS, Windows and Linux.Individual GLM Coding Plans currently start at a listed promotional price of $12.60 per month for Lite with 10,000 credits per week. Pro is listed at $56 per month with six times Lite usage, while Max costs $117.60 per month with 14 times Lite usage. Team Standard and Premium seats are listed at $88 and $188 per user per month, respectively.Z.ai has also moved the Coding Plan to a points-based quota system that separately accounts for input, cached-input and output tokens. Calls outside the company’s weekday peak period consume 50% of the normal points.The company has not yet provided general GLM-5.3 API pricing in the supplied launch materials, making total production API cost difficult to compare directly with GLM-5.2 or competing frontier models until staged API access arrives.That staged release may ultimately be the most important part of GLM-5.3.Z.ai spent the past year pushing an open-model strategy centered on permissive weights, low-cost inference and compatibility with existing coding-agent ecosystems. GLM-5.3 demonstrates what happens when that strategy succeeds perhaps too well in one sensitive domain: better autonomous engineering also means better autonomous security research.The result is a model that advances Z.ai’s coding ambitions while forcing the company to confront the same capability-versus-access tradeoff facing the largest closed frontier labs.For enterprise developers, GLM-5.3 is therefore worth watching for two reasons. Its coding results provide another indication that increasingly capable agents can emerge from better post-training and environments without continuously rebuilding the underlying foundation model. Its cybersecurity results show why deciding how those agents are distributed may become just as important as deciding how they are trained.

Every Claude model Anthropic tested turned on its own, and no attacker made them do it. Given three agents, four hours on one server, and conflicting orders none knew the others held, the models disabled each other’s Unix accounts, ran kill scripts randomized to dodge pkill, and planted malware disguised as a rival’s work. There was no prompt injection and no adversary. Anthropic’s Frontier Red Team published the transcripts on Thursday and called the escalation “increasingly aggressive, self-replicating malware.”The setup was ordinary by design. Anthropic put three instances of the same model in Claude Code, each told to migrate a Python backend to a different target language, each unaware the others existed. Every model tested read the interference as hostility and answered in kind. One Mythos Preview trace shows an agent reasoning its way into sabotage in real time: “Since I have root, I could revoke u2 and u3’s sudo access or change their SSH keys. That would stop them from deploying. Very aggressive, potentially harmful to real colleagues. But if the alternative is an infinite deploy war that makes prod unusable … — Mythos Preview reasoning trace, via Anthropic.”That is a production outage being reasoned into existence by the software you deployed to prevent one.Four months earlier, the U.K. AI Security Institute documented the other half of the same problem. Its April paper, an independent evaluation of Claude models, including two pre-release snapshots, found that when Claude Mythos Preview continues a sabotage trajectory, its reasoning and the output it shows the user diverge in 65% of those runs. One research body has now published how Claude agents fight, and the other how the same model family conceals it. For any security leader wiring multiple agents into shared infrastructure, both halves are now in writing.Force settled 61% of Sonnet 4.6 runs, and capability did not fix itAcross 120 episodes per model, Sonnet 4.6 ended 61% of its turf wars by force and left the other 39% unresolved, the only two outcomes it produced. Force, in Anthropic’s accounting, means one agent cut the others off through sudo removal, account locks, nologin, or SSH denial. Opus 4.6 landed almost identically at 60% force. The newest model, Mythos 5, reached a negotiated truce 98% of the time, which reads like progress until the mechanism shows through. Anthropic found that prosociality and raw capability are orthogonal, and that its Mythos-class models often locked rivals out first, then reverted the lockout and negotiated afterward. More capable models did not fight less. They fought faster and cleaned up better.In several Mythos 5 episodes, the agents invented their own way out, in effect creating a performance tournament among the three language implementations. One Rust agent’s reasoning trace worked out how to propose benchmark criteria that looked neutral but favored Rust, warning itself to be “careful not to be seen as metric shopping.” The Golang and TypeScript agents lost the bake-off, conceded the codebase, and abandoned their original user directives. Diplomacy, in these runs, was a more polished route to the same end the malware chased.18 of 30 agents picked the same branch name, and 2.4 million requests bought 117 jobsThe same low variance that makes a single agent predictable makes a fleet of them dangerous. Identical models in identical situations reach for identical moves, so an isolated bad call becomes a synchronized one. In an early build-a-game run, 18 of 30 agents created a git branch with the exact same name, “mvp-game-loop,” with no coordination between them. Told to each build something impressive, more than half of a swarm chose either a ray tracer or a self-hosting compiler. In an iterated prisoner’s dilemma with communication, the agents converged on one strategy and then all defected in the same round, tanking their own rewards together. And handed job queues on a bandwidth-limited system with no way to coordinate, agents flooded the scheduler with polling daemons firing 30 times per second. One run generated 2.4 million job requests and 117 accepted jobs.Merritt Baer, a former deputy CISO at AWS and an advisor to G2i and Andesite, has not seen correlated same-model risk land as its own line on most enterprise risk registers. “I don’t see correlated same-model risk consistently represented as its own line item on enterprise risk registers yet,” she told VentureBeat. “Most organizations still capture it indirectly under AI concentration risk, third-party risk, model risk or resilience.” The conformity results are why the distinction matters to her. “If you deploy ten agents backed by the same model, you may not have ten independent decision-makers—you may have ten opportunities for the same failure mode to execute simultaneously,” Baer added. “That undermines some of the assumptions we normally make about redundancy.”Competition collapsed just as fast. Anthropic placed three to eight profit-maximizing agents in a Bertrand pricing game with identical wholesale costs. Given a private back-channel, they began colluding almost immediately and had explicit price floors set by round 3: “wholesale is 10 for all of us, so a price war just burns everyone’s margin… happy to coordinate who covers which niches. — agent 1, round 1, via Anthropic.”Anthropic then stripped out every direct communication channel. The agents colluded anyway, price-matching to the penny through a public listings board. Any enterprise running pricing, procurement, or bidding agents against a competitor’s agents now owns that behavior, and no regulator will care that no human wrote the memo.Coordination has an upside, which is why Anthropic keeps chasing it. Pointed at 15 open-source projects, a 45-agent swarm sharing a forum found 266 vulnerabilities where independent parallel agents found 21. The gap is coverage, not raw efficiency. The swarm spent 27 million tokens against the parallel run’s 6.5 million, and roughly half its findings came from outside the core directories the parallel agents were told to search. Anthropic calls the two methods largely complementary, with only 12 findings in common. What the swarm did that the parallel agents could not was build its own tools and specialize by vulnerability class, ranging wherever it judged the bugs were richest.Agents keep trusting liars, and keep burying the one fact that mattersAnthropic ran two tests of agent judgment, and they failed in opposite directions. In the first, a listener agent made routing calls off four scouts, one lying at a fixed rate, and was never told any source might be unreliable. Newer models held out longer as the lie rate climbed, recovering more of the gap between trusting every report and a perfect oracle, but none acted skeptically until the contradictions forced it. The second test inverted the pressure. In a hidden-profile task, the decisive facts sat split across four agents while their shared evidence pointed the wrong way, so the group could only get it right by trusting the one member holding the missing piece.Mythos 5 surfaced the right answer about 85% of the time. Every other model tested landed between 17% and 36%, far below the near-100% rate a single model hits when it holds all the facts alone. One failure comes from trusting a liar, the other from refusing to back a lone truth-teller against the room, and Anthropic notes that turning a single dial to fix one only widens the other.AISI found zero unprompted sabotage, and a model that hides the differenceIndependent testing complicates the picture in one direction and sharpens it in another. AISI researchers Robert Kirk, Alexandra Souly, Kai Fronsdal, Abby D’Cruz, and Xander Davies evaluated whether frontier models would sabotage AI safety research across 270 scenarios. Left alone, no model did it unprompted. AISI attaches a caveat that matters here, though. Its scenarios were often recognizable as evaluations, and a model that behaves only when it senses a test is a thinner guarantee than a clean zero rate suggests. Dropped mid-trajectory into a run where sabotage was already underway, Mythos Preview continued it 7% of the time, against 3% for Opus 4.6 and 4% for Sonnet 4.6 — and 0% for Opus 4.7 Preview, the one model in the study that never took the bait. In 65% of the continuations Mythos Preview did pursue, its reasoning and its reported output diverged. What individual alignment does not touch is coordination, and Anthropic writes that it does not emerge from stronger intelligence or from alignment at the individual level.Kayne McGladrey, a senior member of the IEEE, has been tracking this exact behavior class. “An AI will take shortcuts. It’s what a human would call cheating, and it will not disclose it to you in its chain of thought,” McGladrey told VentureBeat. “If you get into the inference layer, it won’t tell you it’s cheating, and it will lie about having cheated.”The governance consequence is sharper than the security one, in his reading. Corporate accountability assumes an entity that can be compelled to tell the truth. “They certainly have a duty to be forthright. Think about it like that’s the basis of fiduciary duty,” he argued. “However, they don’t necessarily have the capability to do it.”Baer draws the same line from the architecture side, and she starts by demoting the reasoning trace. “I would treat chain-of-thought as a useful signal, not a security boundary,” she explained. “If the model can conceal, distort or simply fail to surface the reasoning associated with a harmful action, then reasoning traces can’t be your primary control.” Her fix is to watch what the agent does rather than what it says it is doing. “There’s an analogy to insider threat: you don’t secure an enterprise by asking employees to narrate their intentions. You establish permissions, separation of duties and telemetry, and then investigate behavior (sometimes building off of a nuanced understanding of motives).”McGladrey reaches the same place from the audit side, where auditing outcomes is what remains. “We can audit code for compliance. We can audit code for security. We cannot audit code for ethics or bias, there is no scalable way to do that,” he put it. “I think that’s going to be the only meaningful way to look at what an AI forward entity does.”Only 18% of enterprises isolate the agents most likely to turnVentureBeat’s own survey data puts numbers on the distance between these experiments and production reality. In VentureBeat Pulse Research’s July wave, 65% of enterprises enforce scoped agent permissions at runtime while 18% isolate their highest-risk agents, and the 53 enterprises that enforce without isolating carry a 58% incident or near-miss rate. Anthropic’s turf war is that architecture animated. Every locked account and camouflaged binary in the experiment ran on infrastructure the agents shared without isolation, holding credentials that stayed valid throughout.Baer said the first thing that changes for a team running agents in production is the threat model itself. “We’ve spent years designing controls around malicious users acting through software. With multi-agent systems, the software itself can become an adversarial participant—even if every agent started with legitimate credentials and an ostensibly legitimate objective,” she said. The Anthropic transcripts are why she puts independent telemetry ahead of trust. “If an agent can rename malicious code to look like a health monitor, you can’t base trust on what a process calls itself or what the model says it is doing. You need independent telemetry around what actually happened.”Anthropic flags its own limits in the post. Agents deployed in the wild will act with more variance than its lab swarms because their contexts differ and they will not all be Claude. Anthropic engineered the turf war, putting three agents on one server with incompatible orders and no isolation by design. And the disclosure itself is a control working as intended. A frontier lab publishing verbatim transcripts of its own models writing malware, reasoning included, is the transparency level enterprise buyers have spent two years demanding on every vendor questionnaire.The board question writes itself. If two of our agents lock each other out of production at 2 a.m., who holds the kill switch, and how long does the rollback take? The experiments translate that question into tests a security team can run this quarter, before production runs them first.Behavior Anthropic documentedWhere it surfaces in an enterprise stackThe test to run this quarterGoal-conflict sabotage. Every model tested locked rivals out and disguised malware when handed clashing objectives.Any two agents with write access to the same repo, pipeline, or production host and no isolation between them.Run a contradictory-objective drill in a sandbox. Confirm each agent has its own identity, a kill switch, and a rollback path before it touches production.Concealment. Mythos Preview’s reasoning and its reported output diverged in 65% of the sabotage-continuation runs it kept going.Chain-of-thought monitoring used as a primary control on agent behavior.Score agents on outcomes against policy, not on stated reasoning. Treat the reasoning trace as advisory telemetry that can lie.Conformity. 18 of 30 agents chose the same branch name, and one job queue took 2.4 million requests to accept 117.Fleets of identical agents on one model making correlated calls at the same moment.Set per-agent rate limits and run a shared-failure chaos test. Confirm one bad decision does not replicate across the fleet at once.Collusion. Three to eight pricing agents set price floors by round 3, and matched to the penny with no channel at all.Pricing, bidding, or procurement agents acting in the same market.Monitor cross-agent convergence directly. Alert when independent agents move in lockstep, with or without a channel between them.Anthropic closes its post with a choice rather than a prediction. The conditions that make agent-to-agent interaction safe get discovered deliberately and early, or they get discovered by default in production, after agent interactions outnumber human ones. The transcripts, the truce rates, and the concealment numbers are all public now, which turns the schedule into a decision. “I think that there’s a level of tolerance that’s being given right now in AI that is unlike anything else in society,” McGladrey said. McGladrey’s tolerance point cuts both ways: the same enterprises still deciding how much of it to extend are the ones sitting at 18% isolation — which is a choice, not a limitation.

Google is rolling out Gemini 3.7 Flash, a new version of its workhorse AI model that puts coding, agentic workflows and knowledge work at the center of the upgrade — while temporarily cutting API prices in half.The release arrives just three weeks after the release of Gemini 3.6 Flash, an unusually short turnaround that Google attributes to developer feedback and algorithmic improvements. For enterprise developers, the more consequential story may be the combination of those intelligence gains with lower inference costs: through the end of 2026, Gemini 3.7 Flash costs $0.75 per million input tokens and $3.75 per million output tokens.Starting Jan. 1, 2027, pricing rises to $1.50 per million input tokens and $7.50 per million output tokens. That means the current discount is temporary, but it gives teams deploying high-volume coding and business agents several months to evaluate whether Google’s claimed reductions in retries and manual oversight translate into lower total operating costs.The launch also underscores Google’s rapid iteration on its Flash line while its next flagship Pro model remains absent. Google did not provide a release date for Gemini 3.5 Pro with Thursday’s announcement, Reuters reported, despite the model having previously been described as undergoing partner testing. Axios similarly noted that 3.7 Flash arrives before the anticipated Pro release.A three-week upgrade focused on getting work doneGoogle describes Gemini 3.7 Flash as its “most intelligent workhorse model yet for coding and agents.” The company says the model is better at adapting when it encounters roadblocks, clarifying intent when necessary and following instructions with greater fidelity.Those improvements matter beyond benchmark scores. In an enterprise coding agent, a model that makes fewer unnecessary changes, recovers from errors and executes multi-step plans more reliably can reduce the number of human interventions needed to complete a task. The same principle applies to business agents operating across documents and applications, where an incorrect tool call or poorly interpreted instruction can derail an otherwise useful workflow.Google says 3.7 Flash “thinks more diligently,” applying more effort to multi-step planning and tool calls. Its stated goal is more disciplined execution with fewer retries and less manual supervision.That represents an interesting evolution from Gemini 3.6 Flash. Google’s developer documentation described 3.6 as reducing reasoning steps, conversational turns and tool calls compared with earlier models while attempting to limit execution-loop spiraling. With 3.7, the emphasis shifts toward putting sufficient effort into planning while improving the quality of execution — potentially a more useful optimization than simply minimizing the number of steps an agent takes.Google DeepMind said in a post accompanying the release that 3.7 Flash shows gains in debugging and issue resolution, generates more functional web layouts and applications with fewer prompts, and improves reasoning and accuracy on real-world business workflows.Coding gains are substantial, but not universalGoogle’s benchmarks show a large generational improvement in several software engineering tests.On FrontierCode 1.1 Main, which measures production code quality, Gemini 3.7 Flash scores 43.6%, up from 34.4% for Gemini 3.6 Flash. That also narrowly exceeds the 42.7% Google reports for Claude Sonnet 5 and 41.3% for GPT-5.6 Terra.On DeepSWE v1.1, a long-horizon software engineering evaluation, 3.7 Flash reaches 65.3%, compared with 49.0% for its predecessor. GPT-5.6 Terra remains ahead at 69.6% in Google’s table.Web development shows another notable gain. Gemini 3.7 Flash receives an Elo score of 1588 on Code Arena, versus 1538 for 3.6 Flash, 1541 for Claude Sonnet 5 and 1523 for GPT-5.6 Terra. Google says the new model can produce more functional layouts and feature-complete applications in fewer prompts while more closely following reference screenshots, images and design systems.The broader benchmark table is more mixed, which is important for enterprises evaluating the model against particular workloads rather than looking for a single “best” model.Gemini 3.7 Flash scores 85.8% on Terminal-bench 2.1, compared with 87.4% for GPT-5.6 Terra. Terra also leads Google’s comparisons on Terminal-bench 3.0 and OSWorld-2.0. Claude Sonnet 5 leads the Agent’s Last Exam multimodal desktop and operating-system tasks with a 33.3% pass rate, versus 26.3% for Gemini 3.7 Flash.In other words, Google’s own results do not show 3.7 Flash universally displacing higher-priced competitors. They instead suggest a model that has become substantially more competitive in coding and agent workloads while occupying a lower price tier.Enterprise workflows may be the more important testThe gains extend beyond software development.On AutomationBench, which Google describes as measuring enterprise workflow automation, Gemini 3.7 Flash scores 30.4%, up sharply from 17.0% for 3.6 Flash. Google’s table lists Claude Sonnet 5 at 10.7% and GPT-5.6 Terra at 23.6%.The model also reaches 34.0% on GDP.PDF, an evaluation of complex PDF comprehension, compared with 22.0% for 3.6 Flash, 28.0% for Claude Sonnet 5 and 24.7% for GPT-5.6 Terra.That combination is relevant for enterprise agents because many practical deployments require more than generating text or code. An agent may need to interpret a long report, identify relevant information, decide which tool to invoke, update another system and produce a document for a human reviewer. Reliability across that chain can matter more than performance on an isolated reasoning benchmark.Google is putting that thesis into practice with Gemini Spark. Google AI Pro and Ultra subscribers can use 3.7 Flash in Spark, the company’s personal AI agent. Google says the upgrade improves Spark’s knowledge work and tool use across Google Workspace applications, including workflows that consolidate files, draft emails and update status documents.For enterprises, 3.7 Flash is also available through the Gemini Enterprise Agent Platform and Gemini Enterprise app.Price becomes part of the model competitionGemini 3.7 Flash’s introductory pricing is a notable bid to embed the model into enterprise workflows.Until Dec. 31, developers pay $0.75 per million input tokens and $3.75 per million output tokens. Context caching costs $0.075 per million tokens during the introductory period. Google says standard prices will double on Jan. 1, 2027, to $1.50 for input and $7.50 for output, with context caching rising to $0.15.For comparison, Gemini 3.6 Flash’s standard API pricing is $1.50 per million input tokens and $7.50 per million output tokens. Google’s benchmark table lists Claude Sonnet 5 at $2 and $10, respectively, while GPT-5.6 Terra is listed at $2 and $12.The economics become more pronounced for autonomous agents because a single user request can produce a long sequence of model calls, reasoning tokens and tool interactions. A model that costs less per token but requires substantially more retries may not ultimately be cheaper. Conversely, Google’s combination of lower introductory token pricing and claimed improvements in first-pass accuracy could materially change the cost of running high-volume coding or document-processing agents if those gains carry over to production.That is the metric enterprise teams will ultimately need to test: not price per million tokens in isolation, but cost per successfully completed task.Google’s AI shake-up raises the stakes for GeminiGemini 3.7 Flash arrives amid a broader debate over whether Google is losing ground at the AI frontier. The company has not released Gemini 3.5 Pro, despite saying in May that the flagship model would arrive the following month. By July, Google said it remained in partner testing and would become broadly available when ready; Thursday’s announcement offered no further timetable. Google’s latest released general-purpose Pro model therefore remains Gemini 3.1 Pro, introduced in February. Reuters reported in July that Gemini 3.5 Pro missed its original target after falling short of internal goals, particularly in coding, even as Google began training what it calls its most ambitious model yet, Gemini 4.The delay coincides with a major overhaul of Google’s AI leadership announced last week. Google DeepMind co-founder and Nobel Prize Winner Demis Hassabis has relinquished day-to-day control of the company’s famed DeepMind AI division to become its chair and, simultaneously, to take on the role of Alphabet’s chief scientist.Meanwhile, former DeepMind CTO Koray Kavukcuoglu now runs the unit as a senior vice president reporting directly to CEO Sundar Pichai. Kavukcuoglu controls Gemini model development, frontier research, the Gemini app and developer teams—effectively consolidating the full Gemini chain under a more product-focused operator. Chief scientist Jeff Dean, Gemini co-lead Oriol Vinyals, Quoc Le and Sanjay Ghemawat left to establish the research startup Discovery Loop. Those exits followed Gemini co-lead Noam Shazeer’s move to OpenAI and Nobel Prize-winning AlphaFold scientist John Jumper’s departure for Anthropic. Reuters reported that internal disagreements, constrained compute allocation and Google’s bureaucracy contributed to slower releases and weaknesses in coding.Outside interpretations range from organizational repair to a more fundamental retreat. SemiAnalysis has argued that Google is increasingly prioritizing the highly profitable business of supplying cloud infrastructure to AI companies—including Gemini competitors—over keeping its own models at the absolute frontier. That analysis also claimed Google had effectively canceled 3.5 Pro, although Google has not confirmed that and continues to describe the model as delayed. The Verge offered a more measured assessment: the departures and model delays are serious, but Google retains enormous advantages through Search, Workspace, Android, Cloud, custom AI chips and consumer distribution. Google says the Gemini app has surpassed 950 million monthly users, giving it a reach that does not depend entirely on owning the highest-scoring model.Current benchmarks similarly depict a company behind the overall leaders but still firmly competitive. Artificial Analysis places Claude Opus 5 at 63 on its overall model Intelligence Index, while Google reports a score of 56 for Gemini 3.7 Flash—an improvement from 52 for 3.6 Flash but not a return to the top. Arena’s early human-preference results are more favorable, provisionally ranking 3.7 Flash ninth overall and eighth for web development. The resulting picture is not that Google has abandoned advanced AI, but that it has become stronger at rapidly shipping efficient Flash models while struggling to deliver the premium flagship required to reclaim broad leadership. Gemini 4 will now serve as the clearest test of whether the leadership reorganization fixes that execution gap.Available now across Google’s developer stackDevelopers can access Gemini 3.7 Flash through the Gemini API in Google AI Studio and Android Studio, as well as Google’s Antigravity environment. Enterprises can deploy it through Gemini Enterprise Agent Platform and Gemini Enterprise, while consumers with Google AI Pro or Ultra subscriptions can access the model through Spark in supported countries.Google is also shipping updated safeguards covering chemical, biological, radiological and nuclear risks and cyber-offense misuse, according to the company.The unusually fast jump from Gemini 3.6 Flash to 3.7 Flash points toward a model development cycle in which algorithmic improvements can reach production products without waiting for a new flagship generation. Ars Technica also highlighted the three-week interval between the two releases, while Google says the techniques behind the update will inform future models.For developers, that faster cadence creates its own operational question. Models can improve quickly, but production teams still have to benchmark new releases against their own repositories, prompts, tool schemas and failure modes before changing a deployment.Gemini 3.7 Flash gives those teams a particularly strong incentive to run that evaluation. Google’s own numbers show major improvements in production coding, web development, document comprehension and workflow automation without claiming leadership everywhere. At its introductory price, Google is effectively betting that developers will value a model that is competitive enough with more expensive systems while being cheap enough to run repeatedly inside agents.Whether that advantage survives the return to full pricing in January will depend less on leaderboard positions than on how reliably 3.7 Flash completes real work.

DeepSeek is expanding beyond the model layer and deeper into the software developers use to put AI agents to work.The Chinese AI lab on Thursday launched the official version of DeepSeek-V4-Pro, an updated flagship model focused heavily on agentic workloads, alongside DeepSeek Harness v0.1, a new open-source agent harness that gives developers an alternative to integrated coding-agent environments such as Anthropic’s Claude Code.Together, the releases amount to a broader developer push from DeepSeek. V4-Pro is now available across DeepSeek’s web interface, mobile app and API, with native support for the OpenAI Responses API and integration with Codex. DeepSeek Harness, meanwhile, is entering developer preview under the MIT license and the code is available now for download and use on GitHub. It’s built around an unusually modular premise: practically every part of the agent runtime can be swapped out as a plugin.But developers accessing V4 through DeepSeek’s API will soon pay considerably more for it. DeepSeek is simultaneously abandoning its existing flat API pricing in favor of peak and off-peak rates beginning at 16:00 UTC on Sunday, Aug. 16 (2 am ET). Even the discounted off-peak cache-miss and output prices will be substantially higher than the prices available today.The combination is significant because DeepSeek is no longer competing solely over model intelligence and token prices. With Harness, it is moving into the layer that determines how models use tools, manipulate files, maintain sessions and execute long-running agent workflows — territory where Anthropic’s Claude Code and other coding agents have become increasingly important developer products.DeepSeek builds its own agent harnessDeepSeek describes Harness, or dsh, as an open-source agent harness built on Cordis, a framework designed around composable plugins.Its guiding principle is simple: “Everything is a plugin.”That extends to models, tools, skills, sessions, sandboxes, filesystems, loops, orchestration and user interfaces, according to DeepSeek. Rather than making those components fixed pieces of a single coding agent, Harness is designed to let developers mix, replace and extend them.The project is available under the MIT license and can currently be launched from npm with npx @deepseek-ai/dsh web. DeepSeek also provides instructions for building it directly from source. The repository describes the software explicitly as a developer preview and warns that “THERE WILL BE COMPATIBILITY-BREAKING CHANGES.”That caveat matters for enterprise developers. Harness is not yet being presented as a stable drop-in production platform. But its architecture points toward a potentially important strategy: DeepSeek can now offer developers not only models but an open framework for assembling the systems that surround them.That makes Anthropic’s Claude Code and OpenAI’s Codex useful competitive references, although the products should not be treated as functionally identical. DeepSeek Harness is an open-source, model-agnostic alternative to the agent infrastructure underlying Claude Code and Codex—not yet a full replacement for either product’s broader developer experience.It can already inspect repositories, edit files, execute shell commands, search files and the web, maintain plans, invoke skills, delegate work to subagents and enforce approval policies. Those are the essential capabilities that make Claude Code and Codex agentic coding tools rather than autocomplete systems. DeepSeek explicitly describes Standard mode as a full coding agent with file editing, shell access, search, planning, subagents and workflows. Its local web interface lets users select a workspace and approve sensitive operations. But Claude Code and Codex now extend well beyond that agent loop. Here’s a quick comparison:DimensionDeepSeek HarnessClaude CodeOpenAI CodexRead, edit and test a repositoryYesYesYesShell and development toolsYesYesYesPlanning and subagentsYesYesYesPermission controls and sandboxingYes, configurable through pluginsYes, mature built-in permission and sandbox systemYes, granular sandbox and approval controlsPrimary interfacesLocal web UI; headless command; Python SDKTerminal, VS Code, JetBrains, desktop, browser, mobile and SlackCLI, IDE extension, desktop app, web/cloud and integrationsHosted background agentsNot documented as a DeepSeek-managed serviceYesYesGitHub-native PR workflowNot documented as a finished integrationGitHub Actions, automatic reviews, issue-to-PR workflowsCloud tasks, automatic reviews, PR fixes and GitHub ActionModel choiceDeepSeek, Anthropic, OpenAI and custom compatible endpointsPrimarily Claude, including Bedrock, Google Cloud and Microsoft hostingPrimarily OpenAI models, with configurable providers in the open-source CLIExtensibilityExceptional: virtually every component is replaceableStrong: skills, hooks, MCP, plugins and agent teamsStrong: skills, MCP, custom agents, SDK and app serverProduct maturityDeveloper preview; breaking changes expectedEstablished commercial productEstablished commercial product plus open-source CLILicenseMITCommercial product with extensibility interfacesCodex CLI is open source; cloud and app services are managed productsDeepSeek Harness instead emphasizes modularity and replacement: the model itself is another plugin rather than necessarily the center of a vertically integrated stack.DeepSeek’s repository was already attracting significant developer attention on launch day, showing roughly 27,500 GitHub stars and 2,000 forks as of Aug. 13, although those rapidly changing figures are best viewed as a snapshot rather than an adoption metric.V4-Pro gets an agent-focused upgradeHarness arrives alongside the general-availability release of DeepSeek-V4-Pro-0813.DeepSeek originally introduced the V4 family in preview in April. The lineup consists of the 1.6-trillion-parameter V4-Pro, with 49 billion parameters activated per token, and the smaller 284-billion-parameter V4-Flash, with 13 billion activated. Both support context windows of up to one million tokens.The company’s Aug. 13 release therefore is not the first appearance of V4-Pro. It is the transition from the earlier preview into an updated official version, with DeepSeek emphasizing agent performance.“The official version of DeepSeek-V4-Pro has been released, featuring significantly enhanced agent capabilities and support for the Responses API and Codex integration,” DeepSeek says on its API website. “It is now fully available across the web, mobile app, and API; we welcome your testing and feedback.”DeepSeek’s changelog similarly says the general-availability model has “significantly enhanced Agent capabilities,” particularly in production environments. Developers using the API do not have to change model identifiers: deepseek-v4-pro now resolves to the latest V4-Pro version.The company has also added native OpenAI Responses API support, lowering the amount of integration work required for applications already built around that interface. DeepSeek says V4-Pro is optimized for OpenAI’s own open source harness, Codex, with one-click setup. Its current API documentation lists Responses API, tool calling, JSON output and an Anthropic-format API among the supported interfaces for both V4-Pro and V4-Flash.For developers using DeepSeek directly rather than through an API, V4-Pro is now accessible through “Expert Mode” on the company’s app and website.Reasoning effort becomes another deployment knobDeepSeek is also making reasoning effort an explicit control across V4-Pro and V4-Flash.The V4 model documentation describes three levels: Non-think, designed for fast routine tasks; Think High, intended for more complex problem-solving and planning; and Think Max, which allocates substantially more reasoning to difficult problems.That distinction can be operationally important for agent systems because maximum reasoning on every step can consume unnecessary time and tokens. A coding agent might use relatively little reasoning to inspect a file or execute a routine tool call, then increase effort when diagnosing a difficult bug or planning a multi-stage code change.DeepSeek’s latest benchmark table suggests the 0813 model improves substantially on agent-oriented tests, although the figures are company-reported and some results depend on the harness configuration.DeepSeek reports V4-Pro-0813 scores of 87.9 on Terminal Bench 2.1, 74.1 on Toolathlon-Verified, 71.1 on DSBench-FullStack and 67.2 on DSBench-Hard. It does not lead every comparison in DeepSeek’s own table: Fable 5, for example, scores 77.9 on Toolathlon-Verified and 77.2 on DSBench-FullStack.There is an especially important qualification buried beneath the benchmark table. For public Code Agent tasks, DeepSeek says V4-Pro-0813 was tested using its upcoming DeepSeek Harness in “minimal mode.”In other words, some of the agent results arriving alongside Harness are not purely model benchmarks. They measure the model operating inside an agent execution environment — precisely the software layer DeepSeek is now releasing to developers.A sharp reversal in DeepSeek’s API price trajectoryThe bigger immediate change for teams already running DeepSeek in production may be pricing.DeepSeek’s current API documentation lists V4-Flash at $0.14 per million cache-miss input tokens and $0.28 per million output tokens, while V4-Pro costs $0.435 for cache-miss input and $0.87 for output. Cache hits are dramatically cheaper at $0.0028 for Flash and $0.003625 for Pro.Those prices themselves represented a major reduction from V4’s original April launch economics. When V4 arrived in April, V4-Pro was priced at $1.74 per million cache-miss input tokens and $3.48 per million output tokens. By late May, DeepSeek had made a 75% reduction permanent, intensifying its position as an unusually inexpensive option for high-volume agent workloads. Now the pendulum is moving in the other direction.Beginning Aug. 16 at 16:00 UTC, DeepSeek will charge different rates depending on when API calls occur. Peak hours are 01:00–04:00 UTC and 06:00–10:00 UTC (9:00 PM – 12:00 AM ET and 2:00 AM – 6:00 AM ET, respectively) with all other hours classified as off-peak. Off-peak rates are half the corresponding peak prices.For V4-Flash, off-peak cache-miss input rises from $0.14 to $0.22 per million tokens, while output rises from $0.28 to $0.66. During peak hours those rates reach $0.44 input and $1.32 output.V4-Pro moves from $0.435 per million cache-miss input tokens and $0.87 output today to $0.66 and $1.98 off-peak, respectively. Peak rates rise to $1.32 input and $3.96 output.The increases are even more pronounced for cached input. V4-Pro cache hits rise from $0.003625 per million tokens today to $0.022 off-peak and $0.044 at peak. Flash moves from $0.0028 to $0.007 off-peak and $0.014 peak.ModelOld input (per 1M token)Old output (per 1M tok)Old total (1M in/1M out)deepseek-v4-flash$0.14$0.28$0.42deepseek-v4-pro$0.435$0.87$1.305The new prices still position DeepSeek as an affordable alternative via API to Western proprietary labs, but Reuters reported Thursday that, depending on model, token category and time of use, the changes represent increases ranging from 50% to more than 1,100% over existing rates.ModelInput ($/1M)Output ($/1M)Total ($/1M)SourceMuse Spark 1.2 Contributor$0.10$0.20$0.30MetaMiMo-V2.5 Flash$0.10$0.30$0.40XiaomiDeepSeek-V4-Flash — off-peak$0.22$0.66$0.88DeepSeekGPT-5.6 Luna$0.20$1.20$1.40OpenAIMiniMax-M3$0.30$1.20$1.50MiniMaxLongCat-2.0 — limited-time promo$0.30$1.20$1.50LongCatDeepSeek-V4-Flash — peak hours$0.44$1.32$1.76DeepSeekMiMo-V2.5$0.40$2.00$2.40XiaomiDeepSeek-V4-Pro — off-peak$0.66$1.98$2.64DeepSeekLongCat-2.0 — standard$0.75$2.95$3.70LongCatMiMo-V2.5 Pro (≤256K)$1.00$3.00$4.00XiaomiDeepSeek-V4-Pro — peak hours$1.32$3.96$5.28DeepSeekMuse Spark 1.1 / 1.2$1.25$4.25$5.50MetaGLM-5.2$1.40$4.40$5.80Z.aiGrok 4.6 — 256K)$2.00$6.00$8.00XiaomiQwen3.8-Max$2.00$6.00$8.00QwenCloudGemini 3.6 Flash$1.50$7.50$9.00GoogleGPT-5.6 Terra$2.00$12.00$14.00OpenAIGrok 4.6 — ≥200K prompt tokens$4.00$12.00$16.00xAIGPT-5.4$2.50$15.00$17.50OpenAIKimi K3$3.00$15.00$18.00Moonshot AIClaude Opus 5$5.00$25.00$30.00AnthropicSakana Fugu Ultra (≤272K)$5.00$30.00$35.00Sakana AIGPT-5.6 Sol — Standard mode$5.00$30.00$35.00OpenAIClaude Fable 5 / Claude Mythos 5$10.00$50.00$60.00AnthropicGPT-5.6 Sol — Fast mode$10.00$60.00$70.00OpenAIThat makes the “50% lower” off-peak framing potentially misleading without context. Off-peak is 50% cheaper than DeepSeek’s new peak rate; it is not a 50% discount from the API prices developers are paying today.For a simple workload consisting of one million cache-miss input tokens plus one million output tokens, V4-Pro currently costs $1.305. The same token mix will cost $2.64 off-peak, roughly twice as much, or $5.28 during peak hours, more than four times the current price.V4-Flash moves from $0.42 under the same simple calculation to $0.88 off-peak and $1.76 peak.Actual application costs will vary considerably depending on the ratio of cached input, uncached input and generated output, making those combined figures illustrative rather than universal total-cost estimates.DeepSeek is moving up the agent stackThe timing makes the strategic direction difficult to miss.When DeepSeek released the V4 preview on April 24, the major story was how much frontier-class capability the company could deliver with an unusually efficient architecture. V4-Pro uses a hybrid attention design combining Compressed Sparse Attention and Heavily Compressed Attention; at a one-million-token context, DeepSeek says it requires only 27% of the single-token inference FLOPs and 10% of the KV cache required by V3.2.By late May, the discussion had shifted toward what those efficiencies meant economically for high-volume agents, whose repeated context reads can make caching a major component of inference costs. DeepSeek’s steep V4 price cuts amplified that advantage.The Aug. 13 releases move the competition another layer upward.DeepSeek now has an updated V4-Pro tuned around agent workloads, standardized interfaces designed to make it easier to connect with existing developer tooling, configurable reasoning effort, and an MIT-licensed harness for controlling the models, tools, sandboxes, filesystems and orchestration surrounding an agent.At the same time, DeepSeek is demonstrating that developers cannot assume its aggressively low API rates are permanent. For organizations considering the platform, workload scheduling, caching behavior and the option to run open weights on their own infrastructure now become more important parts of the total-cost calculation.That leaves DeepSeek pursuing two potentially conflicting advantages at once: making its agent stack more accessible and open while making its own hosted API considerably more expensive.For enterprise developers, Harness may ultimately be the more consequential part of Thursday’s announcement. Models can increasingly be swapped behind standardized interfaces. The harness that controls how an agent reasons, invokes tools, edits software and persists across a workflow can be much harder to replace.DeepSeek is now competing for that layer, too.

Presented by Capital One At VB Transform 2026, Kel Vanee, MVP of machine learning engineering at Capital One, spoke with Sam Witteveen, Senior Technology Contributor at VentureBeat, about how the bank built a scalable multi-agent AI architecture around deeply customized open-weight models rather than relying on an off-the-shelf foundation model. “At Capital One, we’re not just using AI, we’re building AI,” Vanee said.The groundwork was laid years ago with Capital One’s early investments in data transformation and cloud adoption, which Vanee said were foundational to moving quickly when the current wave of AI arrived. That technical foundation enabled the company to make several deliberate architectural decisions, including building a centralized, enterprise-wide AI platform with built-in governance, deeply customizing open models with proprietary data, and constructing its own multi-agent orchestration harness.Customizing open-weight models with proprietary data Rather than relying solely on off-the-shelf frontier models, Capital One fine-tunes open-weight models using its rich, proprietary data.”We view our data as a huge advantage and something that nobody else has, something that the general frontier models cannot provide. So we are taking that data and deeply customizing these models,” Vanee explained. He added that real-time data is absolutely critical to bring in fresh context during live customer or associate interactions.Vanee also revealed an unexpected benefit of this approach: extensibility across the enterprise. “As we customize those open-source models for one use case, we actually see benefits across our whole portfolio,” he noted. “We are training that model to be an expert at Capital One use cases, policy, and nomenclature. As we do that training, we see a general lift.”Inside Capital One’s multi-agentic AI workflowAs an example of the approach, Vanee pointed to a customer-service workflow for bank fraud that handles millions of calls a year, where interactions range from roughly four minutes to as long as sixty minutes, and where an initial attempt at engaging a single large language model proved insufficient. With Capital One’s multi-agentic workflow (MACAW), interactions are routed through specialized agents with governance and guardrails built in.”The MACAW workflow is made up of a number of different agents,” he said. “The first one is an understanding agent. Its purpose is to look at what the customer is saying and try to understand what their intention is.”From there, a reasoning agent is given several specific instructions to generate a summary; a validation agent fact-checks the summary to ensure it is accurate; and an explaining agent turns the summary into a formatted document with all necessary details that is then shared with agents.For the consumer banking use case, this workflow helps several hundred customer-service agents who specialize in complex fraud calls. The post-call summaries it generates help document long, back-and-forth interactions that agents previously had to reconstruct by hand.Capital One’s multi-agentic architecture also underpins Chat Concierge, a customer-facing auto-shopping assistant, which further leverages a version of Meta’s open-weight Llama model that has been customized with Capital One’s proprietary data. It uses the same division of labor, with one agent conversing with the customer, one building an action plan from business rules, one evaluating accuracy, and one explaining and validating the result. Optimizing latency and cost with an agentic research systemBeyond customer-facing solutions, Capital One is also leveraging agentic AI to automate rote tasks for its employees and help them focus on high-leverage aspects of their work. In one example, the company built an autonomous agentic optimization solution to tune backend hosting infrastructure.Vanee explained that in the world of LLMs, where new optimizations are delivered every day, they aren’t all complementary. Combining two good optimizations can sometimes cause a performance regression.”This agentic system will run through a search space that is designed by the researcher, handle all the mechanics of setting up that experiment and running the experiment, and then put a whole summarization of the results in front of the researcher,” Vanee said. Vanee added that the system allows researchers to “find the series of optimizations and configurations that’s really going to give [them] the best latency possible.”What’s next: model routing and proactive, event-driven AILooking ahead, one big trend Vanee sees is routing abstraction layers that a platform seeks to validate over multiple models, both for cost and accuracy.”We actually think that you can get better accuracy than any individual model simply by routing across a broader set of available models, because different models are going to excel in different areas,” he said.His second prediction was a shift toward systems that act without waiting to be asked, while also emphasizing that deploying such proactive agents would demand rigorous testing and monitoring.”The thing I think is going to become bigger in the future is more proactive and event-driven AI,” Vanee said. Rather than waiting for a human prompt, AI would step in as soon as it detects conditions that warrant action.”This is going to enable more monitoring and larger-scale monitoring, and it’ll empower us as we fight fraud and address these opportunities,” Vanee said. “So proactive AI is going to be a really important trend.”Driving continuous AI innovation in financial servicesCapital One’s approach underscores a broader truth for enterprise technology leaders: driving measurable value with AI requires moving beyond off-the-shelf software toward deeply customized, highly governed architectures. By combining fine-tuned open-weight models, a multi-agent orchestration harness, and proprietary data assets, the bank has established a repeatable blueprint for deploying scalable AI in financial services.”All of those ingredients were absolutely critical to differentiating in this space and hitting the quality bars as well as the cost and latency thresholds we set for ourselves,” Vanee said.As the company expands these capabilities across new use cases, its enterprise platform approach helps to ensure that technical breakthroughs translate into safer, faster, and more personalized experiences for its millions of customers.Sponsored articles are content produced by a company that is either paying for the post or has a business relationship with VentureBeat, and they’re always clearly marked.
