A developer tested various fault tolerance patterns for LLM API calls, finding that traditional methods like simple retries and circuit breakers perform poorly. Through over 6000 real API calls, the experiment revealed that these standard patterns fail because LLM API issues are often structural, such as temporary unavailability or rate limits, rather than transient. A novel 'self-healing flywheel' approach, which detects, adapts, learns, and optimizes, demonstrated significant improvement, achieving 100% recovery in some scenarios like invalid model names. AI
