On December 8, 2025, during the 2025 Horizon Robotics Technology Ecosystem Conference, Yu Kai, the visionary founder and CEO of Horizon Robotics, made a grand announcement. He officially introduced the company's fourth - generation Brain Processing Unit (BPU) architecture, which has been christened "Riemann".

In the realm of artificial intelligence and computing, data often exists in high - dimensional forms. However, dealing with high - dimensional data can be computationally intensive and may lead to inefficiencies. The Riemann architecture addresses this challenge by employing a sophisticated technique of reducing high - dimensional data to lower dimensions. This process not only streamlines the data but also optimizes the algorithms and the overall architecture.

The Riemann architecture comes with a host of core advantages that set it apart in the competitive landscape. It offers significantly stronger computing power, enabling it to handle complex tasks with greater speed and precision. Its higher efficiency means that it can achieve more with less computational resources, reducing both time and energy consumption. The architecture also features a richer set of operators, which provides developers with more tools and flexibility to design and implement advanced AI models. Moreover, it exhibits superior energy efficiency, making it an ideal choice for applications where power consumption is a critical factor.

Looking ahead, the Riemann architecture is set to be seamlessly integrated into the Journey 7 series chips. This integration is expected to unlock new possibilities in various fields, ranging from autonomous driving to intelligent edge computing, and further solidify Horizon Robotics' position as a leader in the AI chip industry.
