On August 26, Zhipu launched and open-sourced GLM-5.3-Flash (320B-A18B), the first native multimodal model in the GLM-5 series. It has a total of 320 billion parameters and surpasses GLM-5.2, achieving a score of 57 in the globally recognized Artificial Analysis Intelligence Index (AA Comprehensive Intelligence Index), placing it among the leading models worldwide, on par with Anthropic's popular model Claude Opus 4.8. In the self-developed Z.ai Code Bench evaluation, its programming performance is comparable to that of Claude Opus 4.8. Meanwhile, GLM-5.3-Flash is priced at 1/10 of GLM-5.3, and during a limited-time discount, it is available for 1/20 of GLM-5.3's price, which is 1/40 of Opus 4.8's price. The same intelligence, at 1/40 the cost, provides cutting-edge capabilities without the need to hold back.
