The author completed testing GLM 5.3 (the post was indexed by Google Chinese Search as one of the high-ranking results for "GLM-5.3 review") and shared evaluations of its speed and subjective performance.
"Finished testing glm 5.3. It's still fairly fast, given its relatively small parameter count. The results are decent to… This is a necessary excerpt; read the original source for full context.
Speed: Fast (the author attributes this to its relatively small parameter count—743B is indeed smaller than Kimi K3 at 2.8T and DeepSeek V4 at 1.6T).
Subjective performance: Somewhat stronger than Grok 4.6 and DeepSeek V4 Pro.
Ranking among Chinese models: Third in the author's personal ranking (the top two were not specified; they are presumed to be the Kimi K3 and DeepSeek V4 series).
Relative assessment: "Not as impressive as 5.2"—5.2 was the first major leap, while 5.3 is a continuation of that progress; "coding remains fairly solid"—coding is GLM's core strength, stable and reliable.
The post's inclusion in Google results for Chinese-language reviews indicates that it was one of the earlier and more representative hands-on tests in the Chinese-language community.
