Zhipu's GLM-5.3-Flash Served Record Traffic Entirely on Domestic Chinese Chips

Zhipu's GLM-5.3-Flash — the 320B-A18B model revealed this week as the anonymous "Ox Alpha" — set usage records on OpenRouter and OpenCode, and the company says all of that traffic was served by domestic Chinese chip clusters.

teortaxesTex notes the striking part: these aren't even China's best chips or the current mass-production generation, and the situation should improve by end of year. Huawei 950s were reportedly slated for mass sales in August. A Zhihu contributor reconstructed how Zhipu lined up the infrastructure and read official engineering details for hints on which chips are doing the work. The core takeaway: the bigger story is a frontier-level model handling global-scale real-world inference on domestic silicon, not the model itself.
