Code World Model Rewires World Models

Code World Model makes a compelling architectural bet: let code handle causality and persistence, while generative video handles appearance.

• –Executable state could preserve object attributes, positions, and consequences across long interactions better than pixel prediction alone
• –The programmable proxy translates abstract code into spatiotemporal constraints without requiring a complete 3D asset pipeline
• –The approach is modular: stronger coding agents improve world logic, while better video models improve visual fidelity
• –The current system remains an early prototype, relying on simple interactive worlds and a closed-source game-code foundation
• –Latency, proxy quality, error accumulation, and the difficulty of reliably generating simulation logic remain major obstacles
