专题命中 机器人基础模型 ：为具身智能体提供通用骨干网络
AI总结 提出基于统一混合Transformer架构的全模态世界模型Cosmos 3，联合处理语言、图像、视频、音频和动作序列，在理解和生成任务上达到新最优，为具身智能体提供可扩展的通用骨干。

我们介绍了Cosmos 3，一个全模态世界模型家族，设计用于在统一的混合Transformer架构中联合处理和生成语言、图像、视频、音频和动作序列。通过支持高度灵活的输入输出配置，Cosmos 3无缝统一了物理AI的关键模态——有效地将视觉语言模型、视频生成器、世界模拟器和世界动作模型整合到一个框架中。我们的评估表明，Cosmos 3在一系列多样化的理解和生成任务中确立了新的最优水平，展示了全模态世界模型作为具身智能体可扩展、通用骨干的能力。我们的后训练Cosmos 3模型在技术报告撰写时被Artificial Analysis评为最佳开源文本到图像和图像到视频模型，并被RoboArena评为最佳策略模型。为了加速物理AI领域的开放研究和部署，我们在Linux基金会的OpenMDW-1.1许可证下提供我们的代码、模型检查点、策划的合成数据集和评估基准，网址为https://this https URL License at this https URL }{ this http URL and this https URL。项目网站位于https://this https URL。
We introduce Cosmos 3, a family of omnimodal world models designed to jointly process and generate language, image, video, audio, and action sequences within a unified mixture-of-transformers architecture. By supporting highly flexible input-output configurations, Cosmos 3 seamlessly unifies critical modalities for Physical AI -- effectively subsuming vision-language models, video generators, world simulators, and world-action models into a single framework. Our evaluation demonstrates that Cosmos 3 establishes a new state-of-the-art across a diverse suite of understanding and generation tasks, demonstrating omnimodal world models as scalable, general-purpose backbones for embodied agents. Our post-trained Cosmos 3 models were ranked as the best open-source Text-to-Image and Image-to-Video models by Artificial Analysis, and the best policy model by RoboArena at the time the technical report was written. To accelerate open research and deployment in Physical AI, we make our code, model checkpoints, curated synthetic datasets, and evaluation benchmark available under the Linux Foundation's OpenMDW-1.1 License at https://github.com/nvidia/cosmos and https://huggingface.co/collections/nvidia/cosmos3.
