Artificial Analysis coding benchmark shows GLM5.1 on high pretty close to GPT5.5 xhigh in cost to run, with GPT5.5 on medium significantly less expensive. Compared to GPT5.5 medium GLM5.1xhigh is twice the cost and half the intelligence. They don't have GLM5.2 on there yet, but that'd a big gap to bridge. https://artificialanalysis.ai/agents/coding-agents?coding-ag... I thought I was "holding it wrong" until DeepSWE…
It got 46.2 on DeepSWE in Z.ai's own run[1]. That would put it between Opus 4.7 xhigh and Opus 4.8 medium. [1] https://z.ai/blog/glm-5.2
I'm not accusing anyone specifically, but I've noticed Chinese bots swamping certain YouTube channels that, for example, cover US defense industry news. They'll downplay any and all technical advances, play up China's dominance, US cowardice, etc. All very transparent. I suspect some of the online conversation about open Chinese models is driven by that. How often do you see people talking about Mistral or Trinity? Never. Because they don't play that game.
