Usage with LiteLLM Proxy Server​

Here's how to call a Cerebras model with the LiteLLM Proxy Server

  1. Modify the config.yaml 

    model_list:
      - model_name: my-model
        litellm_params:
          model: cerebras/<your-model-name>  # add cerebras/ prefix to route as Cerebras provider
          api_key: api-key                 # api key to send your model

  1. Start the proxy 

    $ litellm --config /path/to/config.yaml

  2. Send Request to LiteLLM Proxy Server

    import openai
    client = openai.OpenAI(
        api_key="sk-1234",             # pass litellm proxy key, if you're using virtual keys
        base_url="http://0.0.0.0:4000" # litellm-proxy-base url
    )

    response = client.chat.completions.create(
        model="my-model",
        messages = [
            {
                "role": "user",
                "content": "what llm are you"
            }
        ],
    )

    print(response)
