Restore previous GLM 5.1 version

I used to use GLM 5.1 for my fantasy roleplay with broad worldbuilding, and it was the best model from all I tested for it. Every other model loses nuances of worldbuilding and history.

But sometime this month something changes and GLM 5.1 is absolutely terrible, its style is completely bland, lacks commas, likes to chain multiple adjective and verbs together to create almost gibberish responses, all characters sound the same with their personalities non-existent.

I’ve read that GLM 5.1 had an update and was shifted more to agentic coding.

So my request is to put older version of GLM 5.1 as an available variant for those of us who used it for roleplay, because honestly, from non-credit private models it was absolutely the best one

(if you could get GLM 5.1 to be uncensored, it would be additional plus, but I mainly want the original GLM 5.1 over whatever this current crap is)
