Checklist before submitting a PR​

Here are the core requirements for any PR submitted to LiteLLM

  • Add testing, Adding at least 1 test is a hard requirement - see details
  • Ensure your PR passes the following tests:
  • Keep scope as isolated as possible. As a general rule, your changes should address 1 specific problem at a time

Quick start​

1. Setup your local dev environment​

Here's how to modify the repo locally:

Step 1: Clone the repo

git clone https://github.com/BerriAI/litellm.git

Step 2: Install dev dependencies:

poetry install --with dev --extras proxy

That's it, your local dev environment is ready!

2. Adding Testing to your PR​

  • Add your test to the tests/litellm/ directory

  • This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

  • Do not add real llm api calls to this directory.

2.1 File Naming Convention for tests/litellm/​

The tests/litellm/ directory follows the same directory structure as litellm/.

  • litellm/proxy/test_caching_routes.py maps to litellm/proxy/caching_routes.py
  • test_{filename}.py maps to litellm/{filename}.py

3. Running Unit Tests​

run the following command on the root of the litellm directory

make test-unit

4. Submit a PR with your changes!​

  • push your fork to your GitHub repo
  • submit a PR from there

Step 1: Clone the repo

git clone https://github.com/BerriAI/litellm.git

Step 2: Build the Docker Image

Build using Dockerfile.non_root

    -e LITELLM_MASTER_KEY="sk-1234" \
