GLM-4.7

Zhipu, which will IPO on January 8th, dropped a really capable model just before Christmas with 4.7. GLM-4.7 is not close to (API model) SOTA performance on the usual academic benchmarks like GPQA or SWE-bench Verified, but manages to hold its performance beyond that in a broader suite of tasks like GPVal-AA or DesignArena.

I (Florian) have tested this model extensively the last days by using the Z.ai API (and the corresponding coding subscription at $28/yr) in the OpenCode as the CLI (which also offers the model for free at the time of writing) and was more than impressed by the quality of this model. In certain areas (especially in UI generation for websites), I preferred its outputs over Opus, while in other areas, it was more or less on the level of Sonnet 4.5, which was released a mere 4 months ago. However, the model is quite slow (the cheapest coding plan is slower compared to their other offerings) and its long-context performance is worse than other closed models, especially after 100K tokens. Furthermore, it is text-only, which I "fixed" by adding Gemini 3.0 Flash as a subagent in OpenCode. But again, this is an open model, dirt cheap and self-hostable on a node of H100s!
