February 13, 2026 — Beijing‑primarily based 3D AI inference chip firm Suanmiao Expertise (SUNMMIO) has closed two consecutive funding rounds totaling practically RMB 1 billion, based on a number of sources.
The Pre-A spherical was co‑led by Supply Code Capital and Shi Xi Capital, with participation from Lenovo Capital and different semiconductor business funds. The Pre-A1 spherical was led by Xianghe Capital, joined by state‑backed buyers together with CDB Capital and Beijing Shunxi.
Proceeds will fund the R&D and mass manufacturing of 100% domestically produced 3D AI inference chips.
Based in November 2022, Suanmiao Tech focuses on 3D customized‑chips for big mannequin inference, aiming to interrupt the “reminiscence wall” — a bottleneck the place compute models idle whereas ready for information. Its resolution combines architectural innovation with a home 3D IC provide chain cultivated over years.
Suanmiao’s origins hint again to 2009, when founder Wang Fuquan — a former researcher on the Chinese language Academy of Sciences and a key participant within the Loongson (Godson) CPU venture — launched Shengsheng Expertise. There, he led the event of the JASMINER X4, an Ethereum mining chip that used 40nm course of to attain 20x the power effectivity of Nvidia’s 7nm flagship GPUs, producing RMB 800 million in income from a single product line.
The present crew of practically 150 contains Liu Ming (CTO, ex‑Loongson, 6+ years 3D IC expertise) and Lou Jianguang (chief scientist, former Microsoft Analysis principal who collaborated with OpenAI on Excel NLP options, joined in September 2025).
Suanmiao’s in‑improvement chip, A4, adopts a 3D TokenPU structure. Pre‑silicon simulation information reveals inference throughput 1.26x to 2.19x that of Nvidia H200 on Llama and Mixtral fashions.
