Azure Foundry Hosted Agents
Per-session isolated agent sandboxes on Azure — scale to zero, any framework

Microsoft Azure's Foundry Agent Service now offers Hosted Agents in public preview — per-session isolated compute sandboxes purpose-built for running AI agents at scale. Each session gets its own container with a persistent filesystem, internet access (optional), and a Python environment pre-loaded with common agent dependencies. Sessions spin up in seconds and terminate — and stop billing — the moment the agent task completes. The design is framework-agnostic: it officially supports LangGraph, OpenAI Agents SDK, Claude Agent SDK, and Microsoft's own Agent Framework, with others planned. This removes one of the most awkward parts of deploying agents in production: figuring out where they actually run. The persistent filesystem per session means agents can read and write files across their task without external storage configuration. Pricing is $0.0994/vCPU-hour and $0.0118/GiB-hour — competitive with Lambda/Cloud Run for bursty workloads. The service is available in six Azure regions at launch. For enterprises already invested in Azure, this is a compelling "we just figured out the infra" moment. Independent developers can also use it without an enterprise agreement.

Command R Ultra is Cohere's flagship large language model optimized for enterprise retrieval-augmented generation, delivering measurable accuracy gains on multi-document RAG benchmarks. It ships with a structured grounding API that pins answers to specific source citations, reducing hallucination in document-heavy workflows. The model is built for on-premise and private cloud deployment, making it a direct play for regulated industries that can't send data to third-party APIs.
Reviewer scorecard
“Framework-agnostic hosted sandboxes with scale-to-zero is exactly what I need for deploying agents without maintaining my own Kubernetes cluster. The per-session isolation eliminates a whole class of security concerns I was handling manually. The Claude Agent SDK support means I don't have to choose between Azure and my preferred model.”
“The primitive here is clean: a grounding API that returns structured citations alongside answers, not a vague 'here are your sources' footer. That's the right place to put the complexity — the API does the hard work of attribution so you don't have to post-process freeform text to figure out which sentence came from which document. The on-prem deployment story is the real DX bet: if your org has a data residency requirement, this is one of the few models where that's not an afterthought bolted on via a sales call. What I want to see is actual SDK examples and latency numbers under realistic multi-document loads — the blog post gestures at benchmarks but doesn't link methodology, which is a yellow flag I'll hold against them.”
“Public preview means production instability risk and pricing could change significantly at GA. The cold start time for agent sessions needs to be benchmarked against real workloads before committing. And six regions is thin coverage for global deployments — wait for broader availability.”
“Direct competitors are Azure AI Search + GPT-4o and Google's Vertex AI grounding — both backed by orgs with deeper distribution into enterprise IT. Cohere's actual differentiator is on-prem deployment for regulated sectors like finance and healthcare, which is a real problem that neither OpenAI nor Google solves cleanly without custom contracts. The scenario where this breaks is at the retrieval side: if your document chunking strategy is bad, the grounding API just gives you confident wrong citations instead of vague wrong citations — same failure mode, better-dressed. What kills this in 12 months is not a better-funded competitor but the model providers (Anthropic, OpenAI) finally shipping credible on-prem options; Cohere needs to lock in enterprise contracts before that window closes, not after.”
“The battle for agent infrastructure is the next cloud wars — and Microsoft just answered Google Cloud's agent platform launch with their own. Framework-agnostic compute that works with any model provider is a smart commoditization play: own the infrastructure layer, let the model battle play out above it.”
“The thesis is falsifiable: regulated industries will not route sensitive documents through third-party cloud APIs at scale, and therefore the LLM market will bifurcate into cloud-native consumer/SMB and on-prem enterprise, with the on-prem segment demanding citation-level auditability. That's not a vibe — it's driven by GDPR enforcement trends, US state privacy laws, and financial regulators tightening AI audit requirements through 2025-2026. The second-order effect if this wins is interesting: enterprises that lock in on-prem RAG infrastructure become effectively AI-sovereign, which shifts negotiating power away from foundation model labs and toward whoever controls the deployment stack. Cohere is early-to-on-time on this trend; the risk is that the open-weight model ecosystem (Llama 4, Mistral) matures fast enough that enterprises skip the commercial on-prem vendor entirely and self-serve.”
“This is squarely developer infrastructure — not directly relevant to creative workflows unless your studio runs its own agents. Worth watching for the ecosystem tools that get built on top of it.”
“The buyer is a VP of Engineering or CTO at a bank, insurer, or healthcare system with a data residency mandate — that's a real budget line and a real signature authority. The pricing architecture (enterprise contract, on-prem licensing) is appropriate for that buyer and creates meaningful switching costs once the model is embedded in internal tooling. The moat question is the hard one: Cohere's data never goes to the model provider post-deployment, which is a genuine structural advantage, but it requires Cohere to keep winning the model quality race against open-weight alternatives like Llama that enterprises can self-host for free. The business survives if Cohere is the 'enterprise-grade with SLA and support' option in a world where raw model capability commoditizes — that's a plausible but not guaranteed wedge.”
