The GLM-4.7 model isn't that great. I was on their $200/month plan for a while. It was really hard to keep up with how fast it works. Going back to Claude seems like everything takes forever. GLM got much better in 5.1 but Cerebras still doesn't offer that yet (it's a bit heavier). I have a year of Z.ai that I got as a bargain and I use GLM-5.1 for some open source stuff but I am a bit nervous about sending data into their API.
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).
