About

Fabless GPU design selling training (曦云 C), inference (曦思 N), graphics (曦彩 G) and science-AI (曦索 X) GPU lines plus the MXMACA software stack into data centers, telecom-operator procurements and intelligent-computing centers.

Founded 2020

Why it matters

MetaX is the second domestic GPU maker to reach the public market (after Moore Threads) and one of the few with volume training-GPU revenue; operator procurement wins and a fully domestic supply chain for the C600 make it a central beneficiary of China's AI compute localization.
