Troubleshooting Mixtral-8x7B-AWQ on vLLM: Infinite Generation Loop
Patentsmatter · reddit · 2026-08-13
A developer encountered a critical issue while deploying the Mixtral-8x7B-Instruct-v0.1-AWQ quantized model on vLLM 0.27.1: upon receiving a basic prompt, the model continuously generates text until it exhausts the 16384 max model length.
The author shared the startup command, API request parameters, and CLI throughput logs. Logs show a generation throughput of 64 tokens/s, ultimately truncated by the length limit. This infinite generation anomaly exclusively occurs with the Mixtral model.
