Praxis-1

An AI model: a world action model learns to predict how a scene will change and which actions lead there, so that a robot can plan its movements from what it expects to see. This page describes the software, not a robot.

How to read the figures
50HzA
The letter in the grey square after a figure points to the source the figure came from. Pages with several sources carry several letters.
Versions and notes in the key figures (3)

Model type

Developer wording: "our first open-weight world action model".

Access

Runway: "We're actively testing Praxis-1 with early partners across a variety of embodiments"

Base model

Note Runway: "It's built on the same large-scale video pretraining behind our general world models."

The letter points to the source at the foot of the page. Fields without a figure are dashed: the developer does not state them — that is not the same as zero, and not the same as no.

The developer’s own claims
Works across robotsyesA

Developer claim: Praxis-1 "a generalist policy model for robotics developers and researchers that works across any embodiment or environment". The early partners Noble Machines, Standard Bots and Ultra are "each running the model on their own hardware".

Yes only if the developer itself says the model runs on different robot models, for example robots from two manufacturers or two of one manufacturer’s models. Several units of the same robot do not count.

Notes

  • Runway describes Praxis-1 as a world action model.
  • Runway published the Praxis-1 research page in September 2026.
  • Runway's terms of use name the courts in New York County, New York.
