Runway launches Praxis-1, an open robot model 15.6x faster than rivals

US video AI company Runway has launched Praxis-1, a robot model that applies what video models learn about motion and human hands to control real robots. The open-weight model uses an Apache 2.0 license, so developers can run and fine-tune it on their own hardware.

Built on a 27-billion-parameter video foundation model, Praxis-1 runs locally and offers a quantized version for NVIDIA's RTX 5090 GPU. The weights are on Hugging Face and the code is on GitHub.

In tests, Praxis-1 completed 555 of 1,200 scenes on the RoboLab-120 benchmark, a 46.2% success rate, leading in the open robot foundation model category. Runway says it finishes tasks 15.6 times faster than a robotic arm powered by GPT-6 Astra, at about one-51st of the cost per task.
