Usage

Prerequisites - Start LiteLLM Proxy with Beta Flag

:::warning[Beta Feature - Required]

CLI SSO Authentication is currently in beta. You must set this environment variable when starting up your LiteLLM Proxy:


litellm --config config.yaml

Or add it to your proxy startup command:

EXPERIMENTAL_UI_LOGIN="True" litellm --config config.yaml

:::

Configuration

JWT Token Expiration

By default, CLI authentication tokens expire after 24 hours. You can customize this expiration time by setting the LITELLM_CLI_JWT_EXPIRATION_HOURS environment variable when starting your LiteLLM Proxy:

# Set CLI JWT tokens to expire after 48 hours

litellm --config config.yaml

Or in a single command:

LITELLM_CLI_JWT_EXPIRATION_HOURS=48 EXPERIMENTAL_UI_LOGIN="True" litellm --config config.yaml

Examples:

  • LITELLM_CLI_JWT_EXPIRATION_HOURS=12 - Tokens expire after 12 hours
  • LITELLM_CLI_JWT_EXPIRATION_HOURS=168 - Tokens expire after 7 days (168 hours)
  • LITELLM_CLI_JWT_EXPIRATION_HOURS=720 - Tokens expire after 30 days (720 hours)

:::note[Experimental UI Session] When EXPERIMENTAL_UI_LOGIN is enabled, the browser UI login session uses a fixed 10-minute expiry (not configurable). LITELLM_UI_SESSION_DURATION applies only to non-experimental flows. :::

:::tip You can check your current token's age and expiration status using:

litellm-proxy whoami

:::

Steps

  1. Install the CLI

    If you have uv installed, you can try this:

    uv tool install 'litellm[proxy]'
    

    If that works, you'll see something like this:

    ...
    Installed 2 executables: litellm, litellm-proxy
    

    and now you can use the tool by just typing litellm-proxy in your terminal:

    litellm-proxy
    
  2. Set up environment variables

    On your local machine, set the proxy URL:

    (Replace with your actual proxy URL)

  3. Login

    litellm-proxy login
    

    This will open a browser window to authenticate. If you have connected LiteLLM Proxy to your SSO provider, you should be able to login with your SSO credentials. Once logged in, you can use the CLI to make requests to the LiteLLM Gateway.

  4. Make a test request to view models

    litellm-proxy models list
    

    This will list all the models available to you.
