OpenAI has rolled out its most significant memory upgrade since ChatGPT’s original launch. The new system, called Dreaming V3, began reaching ChatGPT Plus and Pro users in the United States on June 4, 2026, and is expected to expand to Free and Go users in the coming weeks.
Unlike the old system, which required users to manually tell ChatGPT what to remember, Dreaming V3 works silently in the background — automatically synthesizing context from many past conversations without any user prompting. The upgrade focuses on three key areas: factual recall, preference adherence, and time-awareness. Notably, the system can now automatically update outdated memories, for example revising a reminder about an upcoming trip to reflect that the trip has already occurred.
A new Memory Summary Page gives users a transparent view of everything ChatGPT has retained about them, with the ability to edit, delete, or add memories at any time. Users who want complete privacy can disable memory entirely or use Temporary Chats, which leave no trace.
Powering the broader rollout is a roughly 5x reduction in compute costs, which makes it possible for OpenAI to extend the feature to free-tier users for the first time. The upgrade affects hundreds of millions of ChatGPT users worldwide and marks a fundamental shift in how AI assistants retain and apply personal context over time.
