李飞飞世界模型公司一年估值暴涨5倍，正洽谈新一轮5亿美元融资

Core Insights - World Labs, founded by Fei-Fei Li, is seeking to raise up to $500 million at a valuation of approximately $5 billion, significantly increasing its valuation from $1 billion in just over a year [2][3]. Funding and Valuation - World Labs has previously raised a total of $230 million, achieving a valuation of $1 billion after its initial funding round in April 2024, which started at around $200 million [3][6]. - The first round of investors included Andreessen Horowitz and Radical Ventures, with subsequent funding rounds attracting major players like NVIDIA and Temasek [6][10]. Product Development - The company launched its first 3D world generation model, Marble, in November of the previous year, which allows users to create explorable 3D worlds based on text or image prompts [7][9]. - Marble utilizes 3D Gaussian Splatting technology to efficiently render scenes while also providing collision meshes for physical simulations [9]. Strategic Vision - Fei-Fei Li emphasizes that world models are crucial for achieving spatial intelligence and are considered the next core focus of AI after large language models [10][12]. - The world model is expected to have broad applications across various fields, including AIGC, robotics, and real-world task execution [12][13]. Competitive Landscape - Another venture, AMI Labs, founded by Yann LeCun, is also attracting investment, with a potential valuation of $3.5 billion, focusing on implicit world models [15][18]. - The landscape of world models is categorized into three layers, with LeCun's approach positioned at the highest abstract level, contrasting with Li's explicit and generative model [18].
