`Grok Code Fast 1` Deprecation Hits All `GitHub Copilot` Surfaces on May 15
FIG-0091:1

`Grok Code Fast 1` Deprecation Hits All `GitHub Copilot` Surfaces on May 15

One more fallback disappears inside GitHub Copilot next week. If your prompts or completion quality depended on this model, re-test now; the switch is close and broad enough to break assumptions.

[ KEY POINTS ]
  1. Grok Code Fast 1 is scheduled for deprecation on May 15, leaving little buffer for teams that pinned workflow expectations to it.
  2. The change spans Copilot Chat, inline edits, ask mode, agent mode, and code completion, so impact is not limited to one entry point.
  3. No replacement or migration detail is included here, which means quality, latency, and behavior shifts need manual verification.
  4. If GitHub Copilot is part of a production coding loop, this is a prompt-regression check rather than a news item to ignore.
