AutoTavern: LLM Agents Build Hearthstone Battlegrounds AI Rivaling Top Players
The headline result is less the game AI itself than the demonstration that LLM agents constructing and verifying research infrastructure outperform those same LLMs playing directly. Practitioners building agent pipelines can study its typed research memory, verification gates and feedback loops as a template for long-horizon autonomous work. The open-sourced TavernGym and TavernBench also give anyone a ready-made RL environment with stochastic, hidden-information decision-making.
