WeRide Unveils WITT Physical AI Cognitive Foundation Model with Atomic Physical Facts

WeRide has unveiled WITT (World Intelligence Toward Truth), a Physical AI Cognitive Foundation Model that builds AI cognition of the physical world through trusted facts extracted from real-world experience. Inspired by philosopher Ludwig Wittgenstein's idea that 'the world is the totality of facts,' WITT introduces Atomic Physical Facts (APFs) as the smallest verifiable units of information. The model uses visual-language model capabilities to decompose real-world environments into verifiable facts, enabling more accurate reasoning and decision-making for autonomous driving.

Within WeRide’s Physical AI architecture, WITT serves as the understanding and evaluation layer, working with the GENESIS simulation model to form a Physical AI flywheel. WITT extracts facts from real-world data, GENESIS generates high-fidelity simulations and long-tail scenarios, and together they continuously improve vehicle-side models. This flywheel has enabled WeRide to become the world’s only company with large-scale commercial deployment of both L4 autonomous driving and L2++ intelligent driving systems.

WeRide has obtained autonomous driving permits in eight countries and operates over 3,000 autonomous vehicles across 40+ cities. Its L4 Robotaxi services run fully driverless in Guangzhou, Beijing, Abu Dhabi and Dubai. The L2++ solution WRD 3.0 has won six consecutive China Urban Intelligent Driving Competitions and been selected for nearly 30 vehicle programs, including models from Chery Exeed and GAC Aion, with testing expansion into Germany, France and Japan.
