What is this error?

When Anthropic reports a model as unavailable or overloaded, the specific AI model you're trying to use cannot process requests right now. This is often temporary and happens during peak usage times, model updates, or capacity issues.

Common Causes

  • The model is overloaded with too many concurrent users
  • Model is being updated or undergoing maintenance
  • The model has been deprecated or renamed
  • Your plan doesn't include access to this specific model
  • Regional capacity issue — model available in some regions but not others

✓ How to Fix It

  1. Check if Anthropic has announced any model changes or deprecations
  2. Try a different model version (e.g., gpt-4 instead of gpt-4-turbo, claude-3-haiku instead of claude-3-opus)
  3. Wait 5-10 minutes and retry — overload is often temporary
  4. Check your plan's model access — some models are limited to higher tiers
  5. Verify the exact model name/ID — typos or outdated names cause this error
  6. Check this page for community reports on model availability
