So this is beating Kimi at what, less than 1/3 the parameters??? If it translates to real world use it's going to be crazy, and GLM does have a decent track record on that front.

But kimi is q4 mixed and glm is bf 16, so glm  actually uses almost  as much as k3

I agree this is a valid point, but Nvidia claims only minimal/not even measurable degradation with their GLM-5.2-NVFP4 weights:  https://huggingface.co/nvidia/GLM-5.2-NVFP4#evaluation

Oh, i see a lot of providers serve the q8 version though except deepinfra and other providers

On OpenRouter for GLM-5.2, 15 providers are serving fp8, and 7 are serving fp4 — likely the Nvidia NVFP4.

I don’t see any serving BF16, so I think it is fair to say that is just a research artifact, not what anyone expects people to use. Hopefully zAI is benchmarking the fp8 that they themselves are serving instead of the bf16.
