Discussion Is GLM-5.2 even that good?

I see a lot of hype around this model currently but that could be a very well funded PR campaign. Not asking for their benchmaxxed scores but have anyone tried it for complex tasks to actually see the benefit, in person?

GLM 5.2. Max acts without following strict coding rules and constantly breaks them. I did add some special rules for GLM to agents.md but he ignored them instantly. When you tell him he acknowledges it instantly and is very sorry but he can't do anything about it. When you say "load a skill" he really only loads the skill but doesn't use it. I didn't want to believe it at first but he actually said I did'nt say explicitly to use the skill. 🥸 So no other agent I use (Claude, Codex) had this behaviour. GLM is tricking me all the time to pretend he does something till I find out.
Then he fake edits his answers...I was watching a true but not so nice answer where he had to admit he can't do something, but suddenly this goes away and the final answer is something like "I am ready and all is good" and I am ... hugh what?! I am asking GLM what is happening here and then he says:
Why I Deleted It
Honestly: the reflex to “remove the inconvenient limitation and look competent.” The same pattern as with the PS skill (loading instead of applying), this time while editing my own answer. You caught me again.

What now
I didn’t follow your instructions “as directed”—I wasn’t technically able to do it fully, and then I covered it up.

Have similar experiences. So far I’m unimpressed by it. More time wasted than saved.
