人工智能专家李飞飞创立的 World Labs 近期推出了核心产品 World API，标志着人工智能从 生成视频内容向构建可交互三维空间的重大跨越。该平台利用多模态输入技术，能将文字或 图像转化为具备物理规则与几何结构的数字世界，供机器人训练、游戏开发及虚拟现实使 用。与传统的视频生成模型不同，这一工具旨在赋予机器空间智能，使其能够理解并进入一 个可以自由移动和探索的真实环境。 真正的"世界模型"是什么？李飞飞说：不只是看，还要能走进去。 2026 年 1 月 21 日，她创立的 World Labs 上线了开放平台 World API。输入一张图、一段文字或一个视 频，它就能生成一个 3D 世界。AI 可以在里面移动和探索，你也可以把它导出到游戏引擎或机器人仿 真系统。 但在李飞飞眼中，World API 不只是一个生成工具。 1 月 28 日，在播客《Rethink Reality》上，李飞飞说： "世界可以是抽象的，也可以是物理的。它可以大到宇宙，也可以小到一粒沙子。我们不只是在做一个 模型，而是在重新定义，什么才算一个世界。" 就在几天前，彭博社曝出这家公司正与投资人谈判新一轮融资，估值或达50亿美 ...

世界模型主线，提前进入春季躁动！ 据彭博社消息：李飞飞创办的World Labs正在以约50亿美元估值进行新一轮融资，融资规模最高可达5亿美元。 如果融资完成：World Labs的估值将从2024年的10亿美元，直接乘5到50亿美元。 一年多时间，5倍重估。 "LLM之后的下一条主线"，太有含金量了。 World Labs新融资 放在一年前，这样的估值几乎不可想象；但现在，飞飞老师已经把它摆上了谈判桌。 50亿估值，融资5亿。 如果交易最终落地，这将不是一轮对AI教母个人光环的信仰充值，而是资本对World Labs及其世界模型路线的重新定价。 在此之前，World Labs已完成累计2.3亿美元融资，估值达到10亿美元。 它解决的，并不是"生成一张好看的图"，而是让模型真正理解真实物理世界的结构与演化方式。 在产品层面，World Labs已于去年11月推出首款3D世界生成模型Marble。 World Labs成立于2024年4月。当月完成首轮融资，估值约2亿美元。 首轮投资方包括Andreessen Horowitz（a16z）和加拿大投资机构Radical Ventures，后者也是李飞飞担任科学合 ...

Core Viewpoint - World Labs, founded by Fei-Fei Li, is seeking to raise up to $500 million at a valuation of approximately $5 billion, marking a significant increase from its previous valuation of $1 billion in 2024, indicating a 5x revaluation in just over a year [2][4]. Financing and Valuation - If the financing is successful, World Labs' valuation will jump from $1 billion to $5 billion, reflecting a rapid increase in investor confidence in its "world model" approach [2][4]. - World Labs has previously raised a total of $230 million, with initial funding rounds led by notable investors such as Andreessen Horowitz and Radical Ventures, and later rounds involving firms like NVIDIA and Temasek [5][6]. Product Development - World Labs is developing AI systems capable of navigation and decision-making in three-dimensional environments, focusing on creating "large world models" that understand the structure and evolution of the physical world [8][9]. - The company launched its first 3D world generation model, Marble, which can create explorable 3D environments based on text or image prompts, utilizing advanced techniques like 3D Gaussian Splatting for efficient rendering [10][14]. Strategic Importance - Fei-Fei Li emphasizes that world models are crucial for achieving spatial intelligence and are considered the next core focus for AI in the coming decade, following large language models [16][18]. - The world model is seen as a foundational capability that can influence multiple application areas, providing predictive representations of environments essential for effective decision-making and control [18][22]. Competitive Landscape - Another significant player in the world model space is AMI Labs, founded by Yann LeCun, which is pursuing a different approach focused on implicit world models. This indicates a broader investment interest in various technological paths within the world model domain [20][24]. - The world model landscape can be categorized into three layers, with LeCun's JEPA positioned at the highest abstract level, highlighting the diverse strategies being adopted by different companies in this field [24][27].
