## Where it stands

- Newer robotics models in the registry since its release: 5:
  - Praxis-1 (2026-09-30) https://postcutoff.com/m/praxis-1/
  - Helix 2.5 (2026-09-17) https://postcutoff.com/m/figure-helix-2-5/
  - UnifoLM-WLA-1.0 (2026-09-10) https://postcutoff.com/m/unifolm-wla-1-0/

  - Generalist GEN-1.5 (2026-08-19) https://postcutoff.com/m/generalist-gen-1-5/
- Closed weights.

## What stands out

- Human-to-robot scaling law (first): Pretrained on 1M+ hours of egocentric human video (~170 years); on-robot normalized score rose from 20% to 53% across 14 tasks as pretraining scaled from 1k to 1M hours. Dyna calls it the first scaling law demonstrated across the embodiment gap. Source: https://www.dyna.co/dyna-2
- World-action model: One video-diffusion (mixture-of-transformers, flow matching) model that denoises future video and an action chunk jointly or separately; one-step distilled video generation 90x faster than the teacher. Source: https://www.dyna.co/dyna-2
- Production quality gains: 87% zero-shot customer-quality pass rate at a customer deployment vs 46% for DYNA-1; 1.55x more task completions than DYNA-1; bottle-cap opening learned with 10 minutes of robot data.

## Notes

Predecessor DYNA-1 (2025) runs in production in hotels, restaurants and laundromats (towel folding etc.). No API or weights; adapts to arms, humanoid prototypes and dexterous hands with hours of local fine-tuning. Figure (Helix 2.5), Generalist (GEN-1) and Dyna all reported human-video scaling in 2026, so 'first' claims overlap. Company-reported.
