Notes

Key features
Positions itself as an omni-bodied model controlling quadrupeds·humanoids·tabletop arms·mobile manipulators in one. The company stresses that the model is not 'a VLM in disguise'.
Notes
Type is Other since VA/VLA status is not disclosed. General-purpose model including locomotion, so only the manipulation part is compared. Announced 2025-07-29 (blog·press release). Blog has no statements on parameters·data hours·compute.
Verification
Confirmed
