## Summary

Microsoft's Foundry blog summarizes October 2026 updates, including the Microsoft Copilot harness in public preview and Browser Automation and the Decisions API reaching general availability. It includes a Python example that asks a typed refund-request question against a gpt-6-luna deployment and reports a recorded probability of 1.0. The post also lists SDK, CLI, and extension changes to check before upgrading.

## Why it matters

The post links October's agent updates to a runnable Decisions API example and to SDK upgrade checks, which helps readers plan a tested adoption.
