Published on July 28, 2026, a GitHub repository collects serving failures that can go unnoticed and describes symptoms, mechanisms, checks, and fixes.
Published on July 28, 2026, the catalog collects LLM serving problems, including incompatible reasoning fields, tool calls displayed as text, quantization labels that do not match active kernels, and misleading health checks.
The entries describe symptoms, mechanisms, checks, and fixes, and may help engineers investigate configurations that appear healthy but produce incorrect responses. Consult the GitHub repository and verify each diagnosis and fix against the documentation and tests for the system in question; the available summary does not report independent validation results.
