Video AI company Runway released Praxis-1, a robotics model it announced in September, with open weights under the Apache 2.0 license. The release includes the weights plus inference and fine-tuning code, and allows commercial use. The model is on GitHub and Hugging Face and runs on Nvidia hardware from H100 and B200 data center GPUs down to Jetson Thor on the robot itself.
Praxis-1 is a 27-billion-parameter mixture-of-experts model built on Runway's video model that predicts video and actions together. According to Runway, it reached 46.2% success on Nvidia's RoboLab-120 benchmark, versus 42.9% for FLUX 3 Action and 28% for π0.5. Launch partners Noble Machines, Standard Bots and Ultra run it on a humanoid, an industrial arm and a warehouse packing station. The results come from the company.
