GPT-5.6 Sol can beat Factorio on peaceful mode
Completing a complex, long-horizon logistics game like Factorio serves as a legible benchmark for how well AI agents handle multi-step planning, system design, and error recovery.

What happened
A developer successfully got the GPT-5.6 Sol model, running in Codex, to autonomously beat the factory-building game Factorio on peaceful mode in 13.5 hours of game time. Interacting via a Python library under human-like game restrictions, the model improved upon GPT-5.5 by using transport belts and ultimately launched a rocket, despite struggling with late-game scaling.
