ChatGPT Memory Fixation Making It 'Borderline Unusable' — 277 Upvotes on Growing User Frustration

r/ChatGPT·medium signal

A r/ChatGPT post (277↑, 110 comments) reports that ChatGPT's persistent memory feature causes the model to fixate on past conversation topics, inserting references to prior projects and contexts into unrelated new sessions. Users describe 'memory contamination' where old preferences are applied in wrong contexts. The high comment-to-score ratio (0.40) indicates deep engagement. This follows reports of GPT-4o memory regression where cross-chat memory started failing — the opposite extreme of the current fixation problem.
