Microsoft Foundry’s GPT-5.6 and Hosted Agents: Building Production-Grade Agent Systems Across Regions

Microsoft has moved GPT-5.6 and production agent capabilities into general availability within Microsoft Foundry, alongside an Asia-Pacific Data Zone and a hosted-agent runtime in the Foundry Agent Service. For teams building cloud-native AI systems, this is more than a new model drop: it’s an update to the production control plane around agent workloads—covering where models run, how agents execute reliably, how they access enterprise knowledge and tools, and how organizations measure quality and cost after deployment.

This matters because agentic applications fail in ways that chatbots don’t: long-running workflows, tool calls, partial failures, identity-bound access, and real operational monitoring. With GPT-5.6 availability, regional deployment options, and hosted agents, Foundry shifts agent development from
