The business problem
The application relies on the retired claude-3-haiku-20240307 model, which is no longer available for use, causing service outages.
How this topic solves it
Migrate the integration to an active, supported model like claude-haiku-4-5-20251001 to restore service and ensure long-term reliability.
- Access the Usage page in the Claude Console to audit current API key and model usage.
- Export the usage CSV to identify all instances where claude-3-haiku-20240307 is still invoked.
- Update the application codebase to replace the retired model identifier with the recommended replacement.
- Perform thorough testing with the new model to verify output consistency before full deployment.
The process of identifying retired models and transitioning to active ones.
Report of active and retired models
Application logic using model IDs
Target replacement model
- Claude Console → Export → Usage CSV
- Usage CSV → Identify retired ID → Codebase
- Codebase → Update and Deploy → Active Model
Expected business outcome
Restored service availability and alignment with current support standards, mitigating the risk of future request failures.
Limitations and checks
Newer models may exhibit different response characteristics; verify behavior by testing applications with newer models well before the retirement date.
