Runway Releases Praxis-1 Robot Model With Open Weights

Runway released Praxis-1, an open-weight robot control model published under the Apache 2.0 license along with its code, moving the controller beyond partner-only testing. The permissive license lets developers use, modify and redistribute the model commercially, a shift from the gated access typical of earlier robotics foundation models. Runway framed the release as a step toward broader adoption, though it cautioned that deploying Praxis-1 on new hardware still requires substantial adaptation work. The move matters because open weights lower the cost of entry for robotics startups and give researchers a reproducible baseline to build on. What to watch next is how quickly third parties port the model to their own robot platforms and whether Runway publishes benchmarks showing how much fine-tuning that adaptation demands.
