Code World Model: Coding Agent as World Brain
The paper proposes using executable code as the persistent state engine behind generated worlds.
Code World Model separates world evolution from visual rendering: a coding agent reasons through events, updates state, and emits code for rule-consistent changes. A proxy representation turns that executable state into frame-level spatiotemporal constraints for a video model. The authors report that, after fine-tuning on paired gameplay data, MiniMax-H3 can follow those proxy specifications while retaining visual detail and motion. Source: HF Daily Papers' note.
