英伟达研究团队近日发布了Cosmos 3，这是一系列全模态世界模型，旨在为物理AI提供一个统一的框架。物理AI指的是能够感知、理解和与物理世界交互的人工智能系统，例如机器人和自动驾驶汽车。Cosmos 3采用混合Transformer架构，能够同时处理和生成语言、图像、视频、音频和动作序列，从而将视觉语言模型、视频生成器、世界模拟器和世界动作模型整合到一个系统中。
该模型支持高度灵活的输入输出配置，使其能够处理多种模态的组合。例如，输入可以是文本和图像的组合，输出可以是动作序列或视频。研究团队表示，Cosmos 3在多种理解和生成任务上达到了新的最先进水平，证明了全模态世界模型可以作为具身代理的可扩展通用骨干网络。在技术报告撰写时，经过后训练的Cosmos 3模型被Artificial Analysis评为最佳开源文生图和图生视频模型，并被RoboArena评为最佳策略模型。
为了推动物理AI领域的研究和部署，英伟达已经开源了Cosmos 3的代码、模型检查点、精选合成数据集以及评估基准。这些资源遵循Linux基金会的OpenMDW-1.1许可证，可通过GitHub和Hugging Face等平台获取。项目网站也提供了更多详细信息。该模型的发布有望加速物理AI领域的创新，降低研究门槛，并为相关应用提供强大的基础模型。
