GLM Quality via Subscription or PAYGO

Ok babes,

my pattern recognition is going berserk.
Here's what I see.

Calls to 4.7 or 5 via coding plan seem somewhat ... dumb. It feels like they run a quantization for that.

When I make calls via OpenRouter, they are good. The quality I was used to get from Z.AI until recently.

Calls via Chutes... well... no. It's chutes. Not even trying that one.

So, what's your experience?

You see the same?
