Z.ai's GLM-5.3-Flash: 320B Model, 7x Cheaper, Runs on Chinese Chips
Z.ai released GLM-5.3-Flash, an open-source model with 320 billion parameters that scores just three points behind its larger sibling GLM-5.3 on Artificial Analysis's Intelligence Index, while costing a seventh as much to run. Notably, all inference traffic for GLM-5.3-Flash ran on Chinese AI chips rather than Nvidia hardware, marking a significant milestone in AI hardware diversification. This cost-performance breakthrough could pressure Western AI labs to optimize for efficiency and alternative chip architectures.
