What happened and what to do
Published on July 28, 2026, the GitHub repository collects examples of silent failures in LLM serving: incompatible reasoning fields, tool calls rendered as text, quantization labels that do not match active kernels, and misleading health checks. For each issue, it describes symptoms, mechanisms, checks, and fixes, helping engineers diagnose configurations that appear healthy but produce incorrect answers.
A company can turn these cases into automated checks for its services: validate response formats, tool execution, alignment between quantization and kernels, and health signals that reflect actual operation. Regression tests and monitoring can alert teams before silent failures affect users.
