These issues and PRs address cases where providers reject the object-form response_format.json_schema (via 400 or 422 errors) and the detection or retry logic fails to handle those rejections correctly. The work focuses on improving fallback behavior so requests are retried without structured output when a provider rejects it by shape or status code.
