Horizon Robotics releases fourth-generation architecture compiler

At the Horizon Robotics Technology Ecosystem Conference 2025, Horizon Robotics released its fourth-generation architecture compiler—the Riemann architecture and the Tiangong Kaiwu compiler. After four iterations, Horizon Robotics' compiler technology has achieved a compilation speed improvement from hours to minutes, while simultaneously improving model performance by 20%. Since 2016, Horizon Robotics' BPU architecture has also undergone four generations of development. Compared to the third-generation architecture, the Riemann architecture will achieve a 10x increase in computing power and a 5x increase in efficiency.
