Xuanzhi says optical computing is entering a real commercial validation phase

智东西 · wechat · 2026-07-27

A long WAIC 2026 report says optical computing is moving from proving feasibility to proving business value.

• Xuanzhi Technology showcased Tianshu · Guanglifu, described as the world’s first optical-electrical AI computing appliance, and used it in a real-time visual perception demo.
• Its latest PACE3 chip reportedly came back from tape-out in June, with a photonic matrix larger than 256×256, aimed at low-latency LLM inference.
• The article argues the main bottleneck is no longer the demo itself, but the lack of software stack, deployment experience, and repeatable commercial scenarios.
• The company is now focusing on concrete workloads such as low-latency inference, vision AI, finance, AI for science, and even space computing.
• The piece frames the next 2–3 years as the key commercialization window for optical computing in China.
