Usage: Serving with SGLang

• Download the weights. You can replace /local/grok-2 with any other folder name you prefer.

  hf download xai-org/grok-2 --local-dir /local/grok-2
  

  You might encounter some errors during the download. Please retry until the download is successful.
  If the download succeeds, the folder should contain 42 files and be approximately 500 GB.

• Launch a server.

  Install the latest SGLang inference engine (>= v0.5.1) from https://github.com/sgl-project/sglang/

  Use the command below to launch an inference server. This checkpoint is TP=8, so you will need 8 GPUs (each with > 40GB of memory).

  python3 -m sglang.launch_server --model /local/grok-2 --tokenizer-path /local/grok-2/tokenizer.tok.json --tp 8 --quantization fp8 --attention-backend triton
  

• Send a request.

  This is a post-trained model, so please use the correct chat template.

  python3 -m sglang.test.send_one --prompt "Human: What is your name?<|separator|>\n\nAssistant:"
  

  You should be able to see the model output its name, Grok.
