UnverifiedOpenAI's 429 errors may be caused by rate limiting or quota exhaustion, and quota exhaustion errors (such as insufficient_quota) should not be retried.76% similarUnverifiedDifferent error types (such as 429 rate limiting versus 500 internal errors) call for completely different retry strategies and fallback plans.75% similarUnverifiedModel-level failover is not transparent: when context windows do not match (for example, switching from a 200K-token model to a 32K model), failing to validate prompt length turns a 429 into a truncation error.74% similarUnverifiedThis performance degradation mainly affects API requests to Claude Fable 5, manifesting as elevated errors.71% similarUnverifiedA common engineering combination: perform a limited number of exponential backoff retries for 5xx and timeouts, and directly trigger degradation for 429 and persistent elevated errors.70% similar
