LLM API relays: How to test stability beyond 99% uptime claims

By PulseAugur Editorial · [1 sources] ·

A technical blog post details how to rigorously test the stability and performance of Large Language Model (LLM) API relays, moving beyond simple uptime claims. The author describes encountering issues where relays falsely reported success (HTTP 200) despite upstream failures, timeouts, or crashes, leading to silent data truncation or errors. The post outlines a three-stage testing system, progressing from basic trials to a sophisticated stream state machine that monitors latency, reliability, and stream quality across multiple regions.
