Coverage keeps confirming the real story behind the reveal: GLM-5.3-Flash runs on 100% domestic Chinese chips, matches top models at a fraction of the cost without Nvidia hardware, and a retrospective says that chip build went unnoticed for weeks before the reveal made it public.
Zhipu quietly built out a 50,000+ Chinese-chip inference base in mid-August while releasing GLM-5.3 with a claimed 50% coding jump, as a mysterious "Ox Alpha" model surfaced in benchmarks rivaling DeepSeek with no confirmed maker. Z.ai then confirmed Ox Alpha was its own model and open-sourced it as GLM-5.3-Flash, a 320B-A18B natively multimodal MoE with a 1M-token context.
State over time
TechNode reports Zhipu's API user base nears 7 million as it quietly adds over 50,000 Chinese AI chips — weeks before that chip choice becomes the Ox Alpha story.
Zhipu releases GLM-5.3, claiming a 50% coding-capability jump and promising open-source weights within two weeks.
