Abstract: TextArena is an open-source collection of competitive text-based games for
training and evaluation of agentic behavior in Large Language Models (LLMs). It
spans 57+ unique environments (including single-player, two-player, and
multi-player setups) and allows for easy evaluation of model capabilities via
an online-play system (against humans and other submitted models) with
real-time TrueSkill scores. Traditional benchmarks rarely assess dynamic social
skills such as negotiation, theory of mind, and deception, creating a gap that
TextArena addresses. Designed with research, community and extensibility in
mind, TextArena emphasizes ease of adding new games, adapting the framework,
testing models, playing against the models, and training models. Detailed
documentation of environments, games, leaderboard, and examples are available
on https://github.com/LeonGuertler/TextArena and https://www.textarena.ai/.
