GitHub Copilot: Auto Model Selection in CLI and Agent Session Streaming for Enterprise

What's new

• Auto Model Selection (CLI): Copilot CLI automatically routes tasks to the optimal model based on real-time availability, code complexity, and orchestration needs
• 10% discount: Auto mode users get a 10% discount on the selected model's cost; switch models anytime via /model
• Agent Session Streaming (public preview): Enterprise customers get real-time access to all Copilot session data — prompts, responses, and tool calls — via streaming endpoint or REST API (past 48 hours)
• Microsoft Purview integration: Native for customers in the Microsoft ecosystem

Why it matters

Auto Model Selection removes manual model selection — the system optimizes for both task fit and cost automatically. Session Streaming is critical for compliance and audit in regulated industries, giving organizations visibility into exactly what agents do.

How to try it

• Auto mode: update Copilot CLI and select Auto in the /model menu
• Session Streaming: Copilot → AI Controls → Enable everywhere for Copilot Usage Records Streaming (Enterprise Cloud with managed users only)
