What changed
Runway's November 11 update makes Praxis-1's weights, inference code, and fine-tuning code publicly available under Apache 2.0, including commercial use. Runway says the model is a 27B-parameter mixture-of-experts diffusion transformer that predicts video and actions together. This is a new access milestone for the model Runway first introduced in September.
Access and availability
Download weights and code from the linked GitHub and Hugging Face repositories, or use hosted inference through vLLM-Omni and Reactor. Runway also says it can be tried on Runway Dev.
Official access documentationWhat you can build
Start with a controlled simulation or supervised robot setup, and validate safety and task performance on the target hardware before deployment.
Limitations
Praxis-1 is a robotics world-action model and requires compatible hardware or an inference environment. Runway's RoboLab-120 results and performance comparisons are provider-reported and are not independent testing.
