GLM-5.3-Flash will likely handle 45% of your AI workloads

GLM-5.3-Flash, identified as the mystery “Ox Alpha” model, is hosted by Z.ai on Chinese chips and priced at $0.15-$0.50 per million tokens (promo 7.5-25 cents). Its open-weight MIT license and strong performance place it at 57 on Artificial Analysis’s intelligence-vs-cost index, offering roughly one-tenth the cost of comparable U.S. mid-tier models. Enterprises such as Uber are already feeling budget strain, prompting a shift toward cheaper Chinese inference providers.
