The new one is quite a bit heavier!

GLM 4.7 is 358B parameters: https://huggingface.co/zai-org/GLM-4.7

GLM 5.1 is 754B parameters: https://huggingface.co/zai-org/GLM-5.1

That said, 5.1 is indeed a bunch better and I could definitely see myself using it for some tasks! Sadly all of the stuff I can actually run locally is still trash (I appreciate the effort behind Qwen 3.6, Gemma 4 and Mistral Small 4 though, alongside others).
