GLM 5.1 and 5.2 appear creatively lobotomized

I have noticed a huge difference in quality, intelligence, creativity from the higher GLMs specifically 5.2. I actually noticed it with 5.2 first. Someone recommended going to 5.1 but it is also is creatively poor. Writing quality is like amateur fanfiction. It also loses itself way faster and forgets.

I know GLM 5.3 just came out but why do they have to lobotomize the earlier versions? Just to sell people to go to the more expensive 5.3? Why would I do that after they just did this? What are other people going to now that 5.2 and 5.1 are toast? Prefer cheaper or free obviously. I cannot afford stuff like the mid or upper tier Claude Opus and Fables.
