This is a preliminary version (and subject to change) of the FP8 quantized google/gemma-4-31B-it model. The model has both weights and activations quantized to FP8 with vllm-project/llm-compressor.

This model requires a nightly vllm wheel, see install instructions at https://docs.vllm.ai/projects/recipes/en/latest/Google/Gemma4.html#installing-vllm

On a single B200:
