Praxis-1 is a 27B-parameter mixture-of-experts diffusion transformer that predicts video and actions together. Built on thousands of LeRobot community datasets, it runs on a single RTX 5090 with NVFP4. The checkpoint and setup instructions are on GitHub at runwayml/praxis-1-oss under Apache 2.0, along with a technical report.
