## 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
```bash
vllm serve RedHatAI/DeepSeek-V4-Flash-NVFP4-FP8 --tensor-parallel-size 4 --port 8089 --kv_cache_dtype="fp8"
```

## 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.

```bash
python tests/evals/gsm8k/gsm8k_eval.py
```

```
Results:
Accuracy: 0.910
Invalid responses: 0.000
Total latency: 173.006 s
Questions per second: 7.624
Total output tokens: 116217
Output tokens per second: 671.752
```

```bash
python3 tests/evals/mmlu_pro/mmlu_pro_eval.py --port 8089
```

```
Results:

## Installation

To run this model in vllm, install the following: 
```bash
uv pip install git+https://github.com/vllm-project/vllm.git@refs/pull/41276/head --no-cache

## Accuracy Recovery Summary

Evaluation performed on 8×B200 GPUs using [vLLM](https://github.com/vllm-project/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).
