DeepSeek-V4-Flash-NVFP4-FP8
Model Optimizations
This model was obtained by using the following branch with LLM Compressor: https://github.com/vllm-project/llm-compressor/pull/2647
Deployment
This model was deployed using the following branch with vLLM: https://github.com/vllm-project/vllm/pull/41276
Evaluation
This model has a noticably lower accuracy recovery than the base model due to the base model being released in a quantized format and differences between mxfp4 and nvfp4.
More advanced techniques such as GPTQ can be used to increase accuracy recovery beyond this model's current state.
For more details on how this model was created and run in LLM Compressor, please contact Kyle Sayers on the vLLM Slack: https://communityinviter.com/apps/vllm-dev/join-vllm-developers-slack

Accuracy Recovery Summary
Evaluation performed on 8×B200 GPUs using vLLM with FP8 KV cache.
Scores are averaged across multiple seeds (3 seeds for most benchmarks, 8 for AIME 2025).
Instruct benchmarks run with reasoning OFF (nonthinking mode); Reasoning and Coding benchmarks run with reasoning ON (thinking mode).
