Runway describes Praxis-1 as a world action model that uses video pretraining to produce controls for physical robots (@runwayml). Its weights are released under Apache 2.0.
In a separate post, @agermanidis says Praxis-1 currently leads the open-weights robotics models on the RoboLab leaderboard. The author points readers to GitHub and Hugging Face for the model weights, code, and fine-tuning methods, and says Praxis-1 runs with NVFP4 on one RTX 5090. These are the author's statements.
The @vllm_project account reports Day-0 support for Praxis-1 in vLLM-Omni and says it was validated on one H100 with 80 GB, a third-party follow-up.
