Microsoft Foundry swaps Model Router pool to GPT-5.6 variants and Claude Opus 4.8, ships Hosted Agents GA
WirelessLife · x · 2026-09-11
Microsoft Foundry's July-August 2026 update makes Hosted Agents, Voice Live integration, and Toolboxes generally available; expands Azure-hosted Claude with structured outputs, web search/fetch, and an MCP connector; and refreshes Model Router's pool with GPT-5.6 variants and Claude Opus 4.8 while retiring older models. The key developer takeaway: no code change doesn't mean no behavior change — re-test quality, latency, and cost. Foundry Local and the Python/JS/Java/.NET SDKs also advanced, with migration notes included.
