Code World Model

Splits world simulation in two: a coding agent maintains persistent world state as executable code and emits an intermediate spatiotemporal proxy representation, which then conditions a fine-tuned MiniMax-H3 video model to render the visuals — reasoning about state in code, realising it in pixels. Trained on paired gameplay and real-world video with aligned RGB-proxy annotations from a purpose-built data pipeline. A GitHub link is up, but the project page carries no parameter counts, resolution, latency or benchmark figures, and states no licence.
