See LiteLLM Proxy code

View all the supported args for the Proxy CLI here

$ pip install litellm[proxy]

If this fails try running

$ pip install 'litellm[proxy]'

Quick Start - LiteLLM Proxy CLI​

Run the following command to start the litellm proxy

$ litellm --model huggingface/bigcode/starcoder

#INFO: Proxy running on http://0.0.0.0:8000

Test​

In a new shell, run, this will make an openai.chat.completions request. Ensure you're using openai v1.0.0+

litellm --test

This will now automatically route any requests for gpt-3.5-turbo to bigcode starcoder, hosted on huggingface inference endpoints.

Using LiteLLM Proxy - Curl Request, OpenAI Package, Langchain, Langchain JS​

curl --location 'http://0.0.0.0:8000/chat/completions' \
--header 'Content-Type: application/json' \
--data ' {
      "model": "gpt-3.5-turbo",
      "messages": [
        {
          "role": "user",
          "content": "what llm are you"
        }
      ],
    }
'

Supported LLMs​

All LiteLLM supported LLMs are supported on the Proxy. Seel all supported llms

$ export AWS_ACCESS_KEY_ID=
$ export AWS_REGION_NAME=
$ export AWS_SECRET_ACCESS_KEY=
$ litellm --model bedrock/anthropic.claude-v2

Quick Start - LiteLLM Proxy + Config.yaml​

The config allows you to create a model list and set api_base, max_tokens (all litellm params). See more details about the config here

Create a Config for LiteLLM Proxy​

Example config

model_list: 
  - model_name: gpt-3.5-turbo # user-facing model alias
    litellm_params: # all params accepted by litellm.completion() - https://docs.litellm.ai/docs/completion/input
      model: azure/<your-deployment-name>
      api_base: <your-azure-api-endpoint>
      api_key: <your-azure-api-key>
  - model_name: gpt-3.5-turbo
    litellm_params:
      model: azure/gpt-turbo-small-ca
      api_base: https://my-endpoint-canada-berri992.openai.azure.com/
      api_key: <your-azure-api-key>
  - model_name: vllm-model
    litellm_params:
      model: openai/<your-model-name>
      api_base: <your-api-base> # e.g. http://0.0.0.0:3000

Run proxy with config​

litellm --config your_config.yaml

More Info

Server Endpoints​

  • POST /completions - completions endpoint
  • POST /embeddings - embedding endpoint for Azure, OpenAI, Huggingface endpoints
  • GET /models - available models on server
  • POST /key/generate - generate a key to access the proxy

Gunicorn + Proxy​

Command: 

cmd = f"gunicorn litellm.proxy.proxy_server:app --workers {num_workers} --worker-class uvicorn.workers.UvicornWorker --bind {host}:{port}"

Code

Quick Start Docker Image: Github Container Registry​

Pull the litellm ghcr docker image​

See the latest available ghcr docker image here: https://github.com/berriai/litellm/pkgs/container/litellm

docker pull ghcr.io/berriai/litellm:main-v1.10.1

Run the Docker Image​

docker run ghcr.io/berriai/litellm:main-v1.10.0

Run the Docker Image with LiteLLM CLI args​

See all supported CLI args here:

Here's how you can run the docker image and pass your config to litellm

docker run ghcr.io/berriai/litellm:main-v1.10.0 --config your_config.yaml

Here's how you can run the docker image and start litellm on port 8002 with num_workers=8

docker run ghcr.io/berriai/litellm:main-v1.10.0 --port 8002 --num_workers 8

Run the Docker Image using docker compose​

Step 1

Here's an example docker-compose.yml file

version: "3.9"
services:
  litellm:
    image: ghcr.io/berriai/litellm:main
    ports:
      - "8000:8000" # Map the container port to the host, change the host port if necessary
    volumes:
      - ./litellm-config.yaml:/app/config.yaml # Mount the local configuration file
    # You can change the port or number of workers as per your requirements or pass any new supported CLI augument. Make sure the port passed here matches with the container port defined above in `ports` value
    command: [ "--config", "/app/config.yaml", "--port", "8000", "--num_workers", "8" ]

# ...rest of your docker-compose config if any

Step 2

Create a litellm-config.yaml file with your LiteLLM config relative to your docker-compose.yml file.

Check the config doc here

Step 3

Run the command docker-compose up or docker compose up as per your docker installation.

Use -d flag to run the container in detached mode (background) e.g. docker compose up -d

Your LiteLLM container should be running now on the defined port e.g. 8000.

Using with OpenAI compatible projects​

Set base_url to the LiteLLM Proxy server

import openai
client = openai.OpenAI(
    api_key="anything",
    base_url="http://0.0.0.0:8000"
)

# request sent to model set on litellm proxy, `litellm --model`
response = client.chat.completions.create(model="gpt-3.5-turbo", messages = [
    {
        "role": "user",
        "content": "this is a test request, write a short poem"
    }
])

print(response)

Debugging Proxy​

Run the proxy with --debug to easily view debug logs 

litellm --model gpt-3.5-turbo --debug

When making requests you should see the POST request sent by LiteLLM to the LLM on the Terminal output

POST Request Sent from LiteLLM:
curl -X POST \
https://api.openai.com/v1/chat/completions \
-H 'content-type: application/json' -H 'Authorization: Bearer sk-qnWGUIW9****************************************' \
-d '{"model": "gpt-3.5-turbo", "messages": [{"role": "user", "content": "this is a test request, write a short poem"}]}'
