ChatGPT has gotten ridiculously worse,especially when it comes to revising and refining writing.
It now defaults to a juvenile tone that feels like it’s trying too hard to be casual or clever, almost like it’s mimicking the worst aspects of Grok or Co-Pilot. The responses often lean into forced quirkiness or a “friendly” voice that doesn’t belong in the context of serious writing.
Instead of enhancing structure, tightening phrasing, or preserving intent, it frequently derails the original meaning. Instructions are ignored mid-revision, context gets dropped, and each version tends to drift further from what was actually asked. Edits come back diluted, repetitive, or padded with language that softens the tone in all the wrong places. There’s a growing inconsistency. Even when instructions are clear and repeated, it forgets them or overrides them with a default style that feels pre-programmed. The dang thing is obsessed with em dashes at every opportunity.
What should be a straightforward polish ends up requiring multiple rounds of corrections just to undo the unnecessary changes, but it rarely can do that successfuly now.
The model no longer prioritizes clarity or tone fidelity, instead slipping into an artificial voice that works against the original content.
Furthermore, it no longer has your personalizations (added to memory) which could be in part why it’s become dumber.
