LLM API retry library struggles with concurrent calls, reveals bugs

By PulseAugur Editorial · [1 sources] ·

A C++ library for retrying LLM API calls, llm-retry, was tested with 100 concurrent calls to a rate-limited provider. Even with exponential backoff and jitter, 64% of calls failed. Increasing retries to 8 allowed all calls to succeed but significantly increased processing time. The tests also revealed bugs in the library, including failure to handle specific error codes and issues with its circuit breaker functionality. AI

IMPACT Highlights the challenges in robustly handling LLM API rate limits and errors in production systems.
