"Like it's 12 years old": users report sudden ChatGPT quality drop, even voice accent changed

Jurgenlklopp · reddit · 2026-10-21

Reddit user Jurgenlklopp reports an overnight quality drop in ChatGPT: it forgets key project details constantly, ignores instructions with an "ahh yes, you're right, my fault" reflex, and only corrects course after being pressed. A fresh chat got worse within 5 minutes.

The most tangible anomaly is voice: it always spoke Swiss German but now talks in standard German with an American or British accent. The user, who says they know how to prompt and configure settings properly, suspects something broke server-side — a typical user-side signal of silent model/config changes.
