### Example: Serving with 16 A100/A800 with int8 Quantization
There are block-wise and per-channel quantization methods, and the quantization parameters have already been uploaded to Huggingface. One example is as follows:
- [meituan/DeepSeek-R1-Block-INT8](https://huggingface.co/meituan/DeepSeek-R1-Block-INT8)
- [meituan/DeepSeek-R1-Channel-INT8](https://huggingface.co/meituan/DeepSeek-R1-Channel-INT8)
```bash
#master
python3 -m sglang.launch_server \
--model meituan/DeepSeek-R1-Block-INT8 --tp 16 --dist-init-addr \

```
### Example: Serving on any cloud or Kubernetes with SkyPilot
SkyPilot helps find cheapest available GPUs across any cloud or existing Kubernetes clusters and launch distributed serving with a single command. See details [here](https://github.com/skypilot-org/skypilot/tree/master/llm/deepseek-r1).
