+### Example: Serving with four A100*8 nodes
 To serve DeepSeek-V3 with A100 GPUs, we need to convert the [FP8 model checkpoints](https://huggingface.co/deepseek-ai/DeepSeek-V3) to BF16 with [script](https://github.com/deepseek-ai/DeepSeek-V3/blob/main/inference/fp8_cast_bf16.py) mentioned [here](https://github.com/deepseek-ai/DeepSeek-V3/blob/main/inference/fp8_cast_bf16.py) first.
 
 Since the BF16 model is over 1.3 TB, we need to prepare four A100 nodes, each with 8 80GB GPUs. Assume the first node's IP is `10.0.0.1`, and the converted model path is `/path/to/DeepSeek-V3-BF16`, we can have following commands to launch the server.
