Humanoid teleoperation system H2 SONIC reaches current quality after 2 days on 4 L40 GPUs
Scobleizer · x · 2026-07-28
The team says H2 SONIC is now live for whole-body teleoperation on full-size humanoid robots. They claim the new version reached this quality after just two days of training on 4× L40 GPUs.
That is a major reduction from the original G1 SONIC, which required 64 GPUs. The post also notes remaining failure modes—wrong URDFs, motor short circuits, and other robotics pitfalls—while the method continues to improve.
