Runway opens 27B robot brain to all
Runway releases Praxis-1, a 27-billion-parameter robotics model under Apache 2.0.
#Robotics#Open-Weight#Runway#VLA#Apache 2.0
🔥 What happened
Runway just dropped Praxis-1 with open weights under Apache 2.0. The 27B-parameter model predicts video and actions jointly, and it's live on Hugging Face, GitHub, and vLLM-Omni today.
💡 Why it matters
Praxis-1 hits 46.2% success on the RoboLab-120 leaderboard, beating FLUX 3 Action (42.9%) and π0.5 (28.0%). The kicker: fine-tuned on the never-seen RT-1 robot, it jumps to 80% success versus the original policy's 52.4%.
⚡ Our take
Open-weighting a 27B world action model is a mic drop. Runway and NVIDIA are commoditizing physical AI and putting every closed-source robotics lab on notice.
