Performance Of Large Language Models As Hearthstone Agents

An LLM-driven Hearthstone agent is developed using the Sabberstone framework to evaluate several models, including GPT-4o, GPT-4o-mini, o3-mini, and GPT-5-mini, across multiple decks and prompting strategies, and results indicate that all evaluated LLMs outperform the random baseline, and GPT-5-mini achieves win rates close to the strongest numerical agents under the evaluation setting.
