How to migrate off anthropic.claude-opus-4-1-20250805-v1:0

  1. Find every place that references it:
    grep -rn --exclude-dir={node_modules,.git,dist} "anthropic.claude-opus-4-1-20250805-v1:0" .
  2. Follow the provider’s migration notes in the official notice.
  3. Re-run your evals or a sample of real prompts — output style, token usage and pricing can change between models.
  4. Check config outside code too: environment variables, feature flags, prompt-management tools, and fine-tuned model references.
  5. Deploy before January 8, 2027, and add the CI scanner so it cannot come back.
