Daily Agentic Field Watch - 2026-09-05 21:00 UTC

• Microsoft pushed GPT-6 Astra into both Microsoft Foundry and Microsoft 365 Copilot on September 4-5 UTC. Foundry now offers Standard and Provisioned Throughput in Global and US Data Zone geographies, while Copilot Cowork and Copilot Studio are rolling the model out through a Limited Access Program. The real signal is the deployment path: Azure is exposing Astra as a governed enterprise runtime, while Microsoft 365 is surfacing it directly in work surfaces.

• GitHub Copilot SDK v1.0.13 is a meaningful agent-runtime release: host-owned external tools now get cancelled when the SDK request or session ends, SDK clients can declare application identity via client info, Node Agent Factories now support paginated run history and notifications, ask_user got selectable session behavior, and session-scoped GitHub credentials can now rotate through a callback. The repo has real traction, with roughly 1.4k forks and 249 issues. Sources: release notes ; repo

• GitHub Copilot CLI v1.0.84-1 shipped GPT-6 Astra support, and the immediately preceding 1.0.84-0 pre-release fixed sandbox and account-handling rough edges: managed sandbox sessions can be disabled from a bypass prompt, sandboxed gh commands now use the logged-in account, /rubber-duck hides when its critic model disappears, and dev-tool caches move out of the sandboxed home. The repo also has visible traction, with roughly 1.9k forks and 2.3k issues. Sources: release notes ; repo

• No other items met the hard gate this pass.
