Runway 开源机器人模型 Praxis-1，登顶 RoboLab-120 基准
Runway's open-source Praxis-1 turns video AI into a robot controller
做视频生成的 Runway 出了个机器人模型，权重和代码全开源，Apache 2.0 随便用，还在 Nvidia 的 RoboLab-120 上拿了 World Action Model 类别第一。机器人方向的研究者和创业公司可以直接下载来微调试试。
Runway 发布机器人控制模型 Praxis-1，权重与源码以 Apache 2.0 许可证开源。模型在 Nvidia 的 RoboLab-120 基准上位列 World Action Model 类别第一。
技术上，Praxis-1 的思路是把视频生成训练中积累的世界知识迁移到机器人控制，让机器人通过视觉理解来执行动作。Runway 此前以视频生成见长，这次是把视频模型能力转向具身控制场景。
局限也很明确：模型目前还无法独立规划复杂动作序列，需要配合其他系统使用。开源策略意味着开发者可以下载权重自行部署和微调，对机器人创业公司和研究者来说门槛比闭源方案低不少，也可能与 Physical Intelligence 等同类玩家形成直接竞争。
Runway's open-source Praxis-1 turns video AI into a robot controller
Runway releases its robotics model Praxis-1 with open weights and source code under the Apache 2.0 license. The model uses knowledge from video training for robot control and leads the World Action Model category on Nvidia's RoboLab-120 benchmark. It can't yet plan complex action sequences on its own, though. The article Runway's open-source Praxis-1 turns video AI into a robot controller appeared first on The Decoder .
