Description:
When serving unsloth/GLM-4.7-Flash-FP8-Dynamic using the vLLM V1 engine on NVIDIA H200, enabling FP8 KV cache results in a complete failure of inference logic. The model enters an infinite repetition loop (e.g., outputting !!!!!!!!!! or repeating the same word indefinitely).
This appears to be a numerical stability issue specific to the interaction between FP8 quantized weights, FP8 KV cache, and the FlashMLA implementation in the V1 engine.
Is this after a few turns or immediately? Can you try removing --kv-cache-dtype fp8 to see if that helpes

Immediately-- kv-cache-dtype autoreturns to normal.
@ShelterW Oh interesting hmmm we were planning to calibrate the KV cache as well, which might / or might not cause issues
If the KV cache turned off works, hmm for now use that - I'll investigate further
@danielhanchen could you investigate it further soon? The number of download of this model is so high! :-)
