Core Viewpoint - The article discusses the development of a novel all-optical chip named LightGen, which addresses the significant computational power shortage faced by large-scale generative artificial intelligence, particularly in visual generation tasks [1][4]. Group 1: Research Development - A research team led by Assistant Professor Chen Yitong from Shanghai Jiao Tong University published a paper in the journal Science on December 18, 2025, detailing their work on the LightGen chip [2]. - The LightGen chip is designed for large-scale intelligent semantic vision generation and integrates millions of photonic neurons to achieve high-resolution image generation, denoising, style transfer, and 3D generation and manipulation [3][4]. Group 2: Performance and Efficiency - Experimental results indicate that the LightGen chip's end-to-end computational speed and energy efficiency exceed that of the most advanced electronic chips by more than two orders of magnitude, paving the way for the advancement of large visual generative models [4].
