## Where it stands

- Newer robotics models in the registry since its release: 1:
  - Praxis-1 (2026-09-30) https://postcutoff.com/m/praxis-1/
- Before it from Figure AI: Helix 02 (2026-01-27) https://postcutoff.com/m/figure-helix-02/
- Closed weights.

## What stands out

- Zero-shot whole-body generalization to unseen homes (first): 56% success (237/420 trials) tidying, towel folding and bed making in 30 never-seen Bay Area homes with no data from those homes; matched Helix 02's success with half the adaptation data. Source: https://www.figure.ai/news/helix-2-5-zero-shot-30-home-generalization
- Pretrained from scratch on human video (Index): Pretrained from random initialization on Figure's Index human-video dataset (not a VLM); without it the same model scored 9%. Source: https://www.figure.ai/news/helix-2-5-zero-shot-30-home-generalization
- Human-to-robot transfer scaling law (first): Predictable scaling of robot performance with human-video data (forecast error 0.54% over an 8x data range). Source: https://www.figure.ai/news/helix-2-5-zero-shot-30-home-generalization

## Notes

'first' flags are Figure's 'to our knowledge' claims (first zero-shot whole-body generalization at this scope; first human-to-robot transfer scaling law measured on a humanoid). Company-reported results. Architecture/parameter counts not disclosed.
