I am continuously experiencing 429 and 503 errors with Gemini 3.8 Flash/3.7/3.6. Even with retries and proper backoff, requests frequently fail again, causing incomplete outputs, increased processing time, and unreliable production workloads.
Please investigate the recurring 429 rate-limit and 503 service-unavailable errors, including service capacity, quota behavior, and recommended retry settings. Improved API reliability for batch processing is urgently needed.
