Runway open-sources Praxis-1 world action model, adapts to new robots in 30 minutes
graceisford · x · 2026-11-11
Runway has released Praxis-1, its first world action model, under Apache 2.0 open weights. It currently tops the RoboLab leaderboard as the leading open-weights robotics model and outperforms other world action models on the benchmark.
Key facts:
- Fast embodiment transfer: tested on 9 different robot embodiments in simulation and on real hardware with partners; reaches good performance on a new embodiment with under 30 minutes of demonstrations
- Runs on consumer hardware: a single RTX 5090 with NVFP4 quantization
- Weights, code and fine-tuning recipes are available on GitHub and Hugging Face
Runway started its robotics work about a year ago on the thesis that video pretraining from its creative models could transfer massively to physical-world interaction — a benefit now clearly materializing.
