HTTP 410 Gone

The resource existed but has been permanently removed and no forwarding address is known.

4xx · Client error✗ not retryable — fix the request instead

In AI APIs specifically

Deprecated API versions and expired file/batch resources return 410 — unlike 404, the provider is telling you it will never come back.

Fix checklist

  • Migrate to the replacement endpoint or model named in the deprecation notice.
  • Re-upload expired files rather than retrying the old ID.
