SuperMimic reportedly beats SONIC's benchmark return after three hours on one GPU

Qiayuan Liao and the SuperMimic team report that their humanoid motion tracker exceeded SONIC's released checkpoint in normalized return across 129,514 motions after three hours on one H100. They calculate more than 1,000 times fewer GPU-hours than SONIC's seven-day run on 128 L40s. The runs used different hardware and amounts of training data, and the benchmark measures coverage of training motions, not generalization.
