Meet ‘Code-as-World’: An Agentic Loop That Rewrites Real Videos Into Executable MuJoCo Physics Programs
MarkTechPost 1 month ago 33
MirroS released Code-as-World, a method that converts real videos into executable MuJoCo physics programs by fitting an editable scene.json rather than predicting pixels, latents, or captions. The agentic propose→execute→verify loop recovers those programs in up to 5 rounds and Code-as-World-VL-9B scores 55.4 MRA on QuantiPhy-validation (above Gemini-3.1 Flash at 54.8). Verified worlds produced by this loop become training supervision with exact physical labels, and MirroS shipped Apache 2.0 code plus 4B and 9B checkpoints with an OpenAI-compatible /v1 vLLM endpoint for internal research use.
