GLM-5.3 tops the open-model rankings and undercuts rivals on price, but its release is delayed

Chinese startup Z.ai has introduced GLM-5.3, which ties for the top position among open-source models on the Artificial Analysis Intelligence Index. The model offers improved performance over its predecessor while undercutting competitors on pricing, signaling a shift in the domestic AI landscape. Although its public release is currently delayed, analysts suggest the upgrade strengthens the market position of Zhipu AI. This development is driving financial institutions to increase their target prices for major Chinese AI firms as competition intensifies.
