What's the story

In a major breakthrough, a team of Chinese scientists has unveiled an optical computing chip that is more than 100 times faster and energy-efficient than NVIDIA's leading AI hardware. The LightGen chip, developed by researchers from Shanghai Jiao Tong University and Tsinghua University, uses the speed of light to perform complex artificial intelligence tasks. The research was led by Professor Chen Yitong and published in the journal Science.

Advanced features

LightGen chip's capabilities and future potential

The LightGen chip packs over two million photonic neurons into a tiny package, enabling it to generate high-resolution images and videos, including 3D scenes. Professor Yitong said that the technology behind LightGen could be "further scaled up." He added that it offers a new way to connect advanced chip architectures with complex AI tasks without compromising performance, at speeds and efficiencies "orders of magnitude greater," paving the way for sustainable AI.

Performance boost

LightGen chip's impact on generative AI tasks

The LightGen chip has shown remarkable performance in generative tasks such as video generation and image synthesis. It is a major step forward in the field of artificial intelligence, especially considering that generative AI models today require massive computing power and consume a lot of energy. The new chip could potentially change this by providing a faster and more efficient way to handle these complex tasks.
