GitHub Copilot Rate Limits & Opus 4.6 Fast Retirement
GitHub enforces new rate limits on Copilot to manage infrastructure strain. Opus 4.6 Fast is retired for Pro+ users. Spread requests evenly or upgrade for higher caps.
TL;DR
- New rate limits rolling out to balance capacity across Copilot infrastructure
- Opus 4.6 Fast retired for Copilot Pro+ users; switch to Opus 4.6 or Auto mode
- Hit a limit? Wait for session reset or upgrade your plan for higher caps
New
- Service reliability limits — Rate limits on overall concurrency to prevent infrastructure strain; you'll see an error and need to wait for session reset
- Model-specific capacity limits — Per-model usage caps; switch to an alternative model or use Auto mode to stay productive
Deprecated
- Opus 4.6 Fast for Copilot Pro+ — Retired effective immediately; use Opus 4.6 as the recommended alternative with similar capabilities
What You Should Do
- Spread requests evenly over time instead of sending concentrated bursts
- Use Auto mode to automatically switch models when hitting capacity limits
- Upgrade your plan for higher rate limits if you're hitting caps regularly
- Check GitHub's rate limiting docs for specific thresholds
Update via GitHub Copilot settings or your IDE extension. Limits roll out over the next few weeks.
