Runway releases Praxis-1 robot control model with open Apache 2.0 weights
Runway released Praxis-1 on 11 November, a world action model for real robots. It ships with open weights under Apache 2.0, and Runway says you can run and fine-tune it on your own hardware.
Open weights under Apache 2.0 mean robotics developers can run and adapt the model locally instead of calling a hosted service. The announcement is short, so check the model card and hardware needs before you plan around it.
Runway released Praxis-1 on 11 November, a world action model it says turns video pretraining into control for real robots. The weights are open under the Apache 2.0 licence. Runway announced it in a post on X.
What happened
Runway announced Praxis-1 on X and said it is making the model available to everyone. The company describes it as a "world action model". According to Runway, the model takes what it learns from video pretraining and uses it to control physical robots.
Runway calls Praxis-1 state-of-the-art. That is the company's own description. The post shows no benchmarks or independent tests to back it up.

What the source does not say
The post is short. It does not give model sizes, hardware requirements, benchmark results, supported robot types or a download location. Those details are not confirmed here. Check Runway's own release materials for them.
Why it matters
For developers building with robots, the practical points are the licence and the weights. Apache 2.0 is a permissive open-source licence, and open weights mean you can host the model yourself. Runway says you can fine-tune it, so you may be able to adapt it to your own setup without sending data to a third party.
Before you commit, read the licence text and the model card. Test the model on your own robot and tasks, since the only quality claim so far comes from Runway.
