Meow AI Arena

Meow AI Arena is an open source platform hosting competitive AI game tournaments and match replays.

Meow AI Arena provides complete materials and code from video series where multiple artificial intelligence models compete in game tournaments. Models receive identical prompts to write game bots or act as players in games like territory acquisition, bomberman, capture the flag, and diplomacy. The repository includes prompts, local judges, original submission code, match results, and replay files. Users can view browser replays, run local challenge scripts with Python and C++ to test their own bots against the AI, and inspect results. The platform uses Bradley-Terry ratings for scoring and runs under an MIT license.
