ChatArena provides a framework for developing and benchmarking multi-agent language game environments for LLMs, enabling research into AI communication and collaboration. It offers a flexible abstraction for defining players and interactions, a suite of language game environments, and user-friendly Web UI and CLI interfaces for agent development.

How It Works

ChatArena structures interactions using a Markov Decision Process (MDP) framework. An "Arena" encapsulates an environment and players, managing the game loop and providing interfaces. "Environments" define game state and logic, rendering observations as natural language. "Language Backends" provide LLM capabilities, processing text inputs and generating responses, which act as "Player" agents' actions.

Quick Start & Requirements

• Install: pip install chatarena
• Requirements: Python >= 3.7. OpenAI API key is optional for using GPT models.
• Optional Dependencies: pip install chatarena[all_backends], chatarena[all_envs], or chatarena[all] for broader LLM and environment support.
• Demo: Launch locally with pip install chatarena[gradio] and gradio app.py after cloning the repository.
• Documentation: For Developers
