Runway released Praxis-1, an open-weight robotics control model built on a 27B-parameter video foundation model under Apache 2.0, runnable and fine-tunable on local hardware. Runway claims it completes robotic arm tasks 15.6x faster than a GPT-6 Astra-driven setup at 1/51 the per-task cost, leading the world-action-model category on the RoboLab-120 benchmark.
