Enable Claude Sonnet 4.6 in Copilot Enterprise Model Policies

Briefing for: Operations
What happened
GitHub will remove Claude Sonnet 4 from all Copilot experiences on May 1, 2026. For Enterprise customers, access to the replacement model, Claude Sonnet 4.6, must be manually enabled through model policies in the Copilot settings.
Why it matters
As an administrator, you must update organization-level policies to ensure developers have access to supported models. If the policy for Sonnet 4.6 isn't enabled by May 1, developers who prefer Anthropic's models will lose access, potentially causing friction in their established coding workflows.
What this enables
- If you manage Copilot Enterprise, verify that Claude Sonnet 4.6 is toggled 'on' in your organization model settings today.
- If you track developer tool usage, monitor the transition to version 4.6 to ensure teams are prepared for the removal of the older model.
