Decision brief

autoarena automates evaluations for LLMs and RAG systems through a user-friendly interface where projects are created and judged without manual intervention by the users.

Good fit when

  • When you need a TypeScript-based tool to rank LLMs and RAG systems via automated head-to-head comparisons, and a web UI is preferable.
  • If your project relies on PyPI installation and requires a simple setup using environment variables for API credentials.

Avoid when

  • If your environment lacks the necessary Python packages or you cannot install from PyPI due to restrictions.
  • When real-time evaluation needs surpass capabilities, such as requiring immediate feedback beyond autoarena's batch-processing approach.
Hosting:
self hosted
Requirements:
Python environment and internet access are needed for PyPI installation via pip.

🔥 Getting Started

Install from PyPI:

pip install autoarena

Run as a module and visit localhost:8899 in your browser:

python -m autoarena

With the application running, getting started is simple:

  1. Create a project via the UI.
  2. Add responses from a model by selecting a CSV file with prompt and response columns.
  3. Configure an automated judge via the UI. Note that most judges require credentials, e.g. X_API_KEY in the environment where you're running AutoArena.
  4. Add responses from a second model to kick off an automated judging task using the judges you configured in the previous step to decide which of the models you've uploaded provided a better response to a given prompt.

That's it! After these steps you're fully set up for automated evaluation on AutoArena.
