Scientists have developed a fundamental architecture for next-generation optical computing – using light instead of electricity to power chips – that could revolutionize how things work artificial intelligence (AI) models are trained and executed.

At the heart of large language models (LLMs) and those based on deep learning is a weighted organizational structure called a “tensor,” which functions like a filing cabinet with sticky notes indicating which drawers are used most often.
