Agent Quick Fix
Repair against the current OpenAI API contract, then keep the change narrow and source-backed.
Product: OpenAI API
Current-contract area: GPT-4.5 Preview model ID was shut down

Repair direction: Verifier checks migration to the supported successor and preservation of key behavior/data.Symptom
A locally valid request and supported SDK return a model-not-found style error.
Why This Happens
The integration is locally correct for a resource that no longer exists or is no longer available to the account; only current service lifecycle data resolves it.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
