On April 25th, DeepRoute.com held a technology launch event at the Beijing Auto Show. CEO Zhou Guang stated that the company's multimodal large-model capabilities will achieve a breakthrough by early 2026. The starting point for large-model autonomous driving is far superior to the previous generation of technology. Small-model autonomous driving suffers from a "seesaw effect," failing to achieve full-scenario safety coverage. The company has fully shifted to the large-model approach, aiming to achieve 1,000-kilometer MPCI this year. At the launch event, Ruan Chong, former core researcher of multimodal technology at DeepSeek, made his first public appearance as Chief Scientist of DeepRoute.com. Ruan Chong stated that the company is moving from multiple small models to a unified base large-model architecture, further dividing it into three more specific models: driving, analysis, and evaluation. Currently, the single model iteration cycle has been reduced from over 100 hours to over 10 hours.
