Users hit ChatGPT "memory full" wall: new chats re-trigger the error after 5 messages

PK-Laharl · reddit · 2026-10-21

Reddit user PK-Laharl reports roleplay conversations repeatedly interrupted by a "Chat memory full" prompt: starting a new chat — with or without the previous context — re-triggers the error after about 5 messages, and clearing memory doesn't help either. The issue has persisted for over a day.

A screenshot shows OpenAI offering two options: continue in a new chat with an automatic summary, or upgrade to Plus for expanded memory per chat. The post asks whether others are hitting the same wall, pointing to tighter context/memory limits on the free tier.
