Lumai develops optical computing systems designed to accelerate AI inference for large language models with increased performance and efficiency.

Lumai specializes in optical computing technology, offering the Lumai Iris, which is presented as the world's first optical computing system capable of running billion-parameter Large Language Models (LLMs) in real time. The company claims its processor significantly outperforms traditional transistor-only accelerators, with a roadmap aiming for a 50x increase in AI performance. The technology utilizes 3D optical components, which Lumai states leads to a 90% reduction in power consumption and a 10% reduction in total cost of ownership compared to silicon-only solutions. The system is designed for datacenter-scale AI inference, supporting ultra-efficient operations without the need for liquid cooling and eliminating throughput constraints at scale. It features massive spatial parallelism and a three-tier memory architecture optimized for AI workloads, including efficient KV Cache.
