Chong Zhang (ETH Zurich) released supermimicvibed, an unofficial reproduction of SuperMimic (arXiv 2610.28480) on humanoid whole-body control with a differentiable world model — 867 stars already.
- No official code exists, so everything was implemented from the paper, vibe-coded with an AI assistant in 1 hour, on Isaac Lab 3 (MuJoCo-Warp, kit-less)
- Targets the paper's Fig. 4a LAFAN1 comparison: 40 G1-retargeted clips (2.45h), single GPU; the paper hits normalized return 0.82 after 1.2h on an H100, and this repro passes LAFAN within 1.5 GPU-hours
- The author just pushed a diff aligned with details from official code, offering an easier upgrade path for anyone building on his implementation
