Latest update (11-12 02:26): Runway releases open-weight Praxis-1 robotics model trained from video

Overview: Runway makes its Praxis-1 world action model available on November 11, 2026, with open weights under the Apache 2.0 license so users can run and fine-tune it on their own hardware. Runway describes the model as turning video pretraining into control for real robots. IT之家 reports that Praxis-1 is built on a 27-billion-parameter Runway video foundation model and includes an NVFP4 quantized version for the RTX 5090.

Runway says Praxis-1 ranks #1 on NVIDIA's RoboLab-120 leaderboard and leads every open-weight VLA on the board, including π0.5 and GR00T N1.6. The report does not include leaderboard scores, so the ranking rests on Runway's claim.

vLLM says it added day-0 support for Praxis-1 in vLLM-Omni, covering offline inference and OpenPI / Positronic serving. vLLM says it qualified the integration on a single NVIDIA H100 80GB.
