NVIDIA 发布 Cosmos 3 四个开放世界模型
原标题：New NVIDIA Cosmos 3 Open Models for Interactive World Simulation
AI 摘要
NVIDIA 在 Hugging Face 发布 Cosmos 3 世界模型家族的四个新开放权重检查点，均基于 Cosmos 3 Nano 后训练，拥有 160 亿可训练参数，采用 OpenMDW1.1 许可，允许商用与非商用。四个模型分别面向自动驾驶多视角数据生成、相机与 LiDAR 同步流式仿真、物理模拟器控制转逼真视频，以及双臂机器人动作预测。NVIDIA 称这些开放权重与后训练配方为世界模型研究提供共享起点，但模型在忠实支持策略学习与评估方面仍存挑战。
