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.

Gemma 3n
Open-weight multimodal AI that actually runs on your phone

Gemma 3n is a family of open-weight multimodal models from Google DeepMind designed to run efficiently on mobile and edge hardware. The models accept text, image, and audio inputs and are optimized for consumer-grade devices using a novel per-layer embedding parameter technique. Released under an open-weights license, they're aimed at developers building on-device AI applications without cloud inference costs.
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 a quantization-aware multimodal model architecture that uses per-layer embedding parameters (MatFormer-style) to scale compute at inference time, not just at training time — that's a real technical bet, not a marketing claim. The DX bet is "drop it into your mobile pipeline with minimal config," and the Hugging Face availability plus Keras/JAX support means the first 10 minutes don't involve fighting an SDK. The honest comparison is llama.cpp with a vision adapter, and Gemma 3n beats that story on audio support and official tooling. The specific decision that earns the ship: Google actually published the architecture details and benchmarks with methodology, which is rare enough to reward.”
“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 Phi-4-mini, Llama 3.2 1B/3B, and Apple's on-device models — Gemma 3n has to beat all of them to matter, and on audio input it does differentiate. The scenario where this breaks is production mobile deployment at scale: open weights don't mean optimized runtime, and getting consistent latency on fragmented Android hardware is still a six-week engineering project nobody budgets for. What kills this in 12 months isn't a competitor — it's that Apple Intelligence and on-device Gemini Nano ship natively into OS-level APIs and developers stop caring about custom model integration entirely. Still ships because it's genuinely the most capable open multimodal model at this parameter count, and the open-weights license means no API cost cliff.”
“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 here is falsifiable: by 2027, the majority of AI inference for personal use cases runs at the edge, not in the cloud, because latency, privacy regulation, and connectivity costs make server-side inference uneconomical for routine tasks. Gemma 3n is well-positioned for that thesis — the per-layer scaling means the same model family can target a $200 Android phone and a high-end laptop without separate fine-tuning runs. The second-order effect that matters: open-weight on-device models shift monetization away from inference API providers toward fine-tuning services, hardware optimization tooling, and enterprise deployment wrappers — Qualcomm and MediaTek gain power here, OpenAI's API business loses ambient inference revenue. Google is riding the NPU proliferation trend, and they're on-time, not early — the risk is that the trend already happened and Samsung and Apple locked up the premium tier.”
“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.”
“There's no business here for Google in the conventional sense — this is defensive open-source strategy to prevent Llama from becoming the default on-device model layer, which is a legitimate move for a platform company but not a product anyone builds a startup on top of. The buyer question for derivative products is real: who writes the check for an app built on Gemma 3n versus one built on a vendor API? The answer is an enterprise IT buyer who cares about data residency, and that buyer wants SLAs, not open weights. The moat for Google is ecosystem lock-in through Android and Chrome, but that only accrues to Google — the developer building on these weights has no defensible position because the weights are free to anyone and Google can deprecate the version without notice. Derivative businesses are viable only if they add a proprietary fine-tuning or deployment layer on top.”
