Version: 1.1.5 or gpt 4.1 one of them is ill

Describe the Bug

just updated, been working smoothly with gpt 4.1 for weeks, love it.
until today, and its hopeless. hours of silly basic mistakes in really simple stuff.
almost endlessly ■■■■■■■■ things up.

replicating code. not fully reading short files. not being able to understand the most basic things. and 4.1 was by far the best model for me before this. now I want to strangle it.

Steps to Reproduce

try doing anything you would normally do easily using gpt 4.1

Operating System

MacOS

Current Cursor Version (Menu → About Cursor → Copy)
