**A Chinese physical AI start-up, Fysics AI, has launched a new world model that embeds real-world physics directly into its code, challenging the data-driven approaches of OpenAI and Meta.** The Shanghai-based firm, founded by former Nvidia senior manager Zhang Lihua, unveiled the Fysiverse model on Wednesday, claiming it solves common issues like physical illusions and reasoning failures. This paradigm shift aims to simulate reality with computable, controllable dynamics rather than relying on massive video datasets or black-box learning.</p><p class="summary-lead">**The world model sector currently follows three dominant paradigms: video-based generation (OpenAI's Sora), self-supervised black-box learning (Meta's V-JEPA), and 3D modeling (World Labs' Marble).** Fysics AI argues these methods all have critical flaws—video models learn correlation, not causation; black-box knowledge is hard to validate; and 3D models struggle with real-world material and contact properties. By contrast, Fysiverse first reconstructs a scene's 3D geometry, then uses a physics simulator to calculate movements and interactions before rendering lifelike outputs.</p><p class="summary-lead">**The implications are significant for robotics, autonomous driving, and content creation, as Fysiverse offers a more reliable foundation for training AI in physical tasks.** The start-up's demos, including cabinets falling like dominoes and a bouncing teddy bear, show more natural and realistic scenes than nine unnamed competitors. Founded in 2024 by Zhang Lihua—a key contributor to Nvidia's PhysX engine and now a vice-dean at Fudan University—Fysics AI has backing from investors including MPC and MetaX.</p><p class="summary-lead">**This new paradigm could accelerate the development of general-purpose physical simulators, bypassing the scaling limitations of video-based models.** By embedding laws of physics directly into code, Fysiverse reduces the need for massive, curated datasets and offers greater interpretability. However, the approach may face challenges in scaling to highly complex or unpredictable real-world environments.</p><p class="summary-lead">**What to watch next:** Whether Fysiverse can attract major industry partnerships and prove its physics-first approach outperforms data-driven models in real-world robotics and autonomous vehicle deployments.
