At CES 2026, Nvidia unveiled Alpamayo, a 10-billion parameter open-source AI model for self-driving cars. The first production vehicle to use it is the Mercedes-Benz CLA, launching in Q1 2026 with point-to-point city navigation. Jensen Huang called it the ChatGPT moment for physical AI. Nvidia is offering 1,000 TOPS of compute power, five times more than competitors, and releasing the model weights on HuggingFace for anyone to use. Partners include Mercedes, JLR, Lucid, Uber, Bosch, and ZF. This is the first time a production-grade autonomous driving stack has been open-sourced.
