GPT-5.6 Sol can beat Factorio on peaceful mode

GPT-5.6 Sol successfully completed a peaceful Factorio game in 13.5 hours using a game manager interface that enforces standard gameplay restrictions. While the model demonstrated improvement over previous attempts—particularly in using transport belts—it showed scaling limitations in late-game stages and relied on manual workarounds to achieve the rocket launch. The researcher views autonomous Factorio play as a valuable medium for understanding AI model capabilities and plans to test additional models and difficulty levels.
