New Memory Architecture Launch
On June 4, 2026, OpenAI announced the rollout of a redesigned memory synthesis system for ChatGPT, aimed at improving the accuracy and relevance of memory recalls while efficiently scaling across millions of users and years of conversations. This new architecture, referred to as Dreaming V3, builds upon the previous Dreaming framework and is designed to be more compute-efficient.
Evolution of Memory Features
ChatGPT’s memory capabilities have evolved significantly since their inception. Initially launched in April 2024, the memory system, known as “saved memories,” allowed the model to record information only when explicitly stated during conversations. This system relied heavily on specific cues to trigger memory storage, which often led to stale or irrelevant recalls.
In April 2025, OpenAI introduced Dreaming V0, a background process that enabled ChatGPT to curate memories from chat history automatically. This advancement allowed the model to incorporate context that users did not explicitly instruct it to remember, enhancing the personalization and freshness of interactions. However, Dreaming V0 was not sufficient as a standalone memory system.
The latest update, Dreaming V3, represents a significant leap forward, synthesizing a cohesive and up-to-date memory state from numerous conversations, thus improving the overall user experience.
User Interaction with Memory
OpenAI has established three key objectives for evaluating memory performance: carrying forward useful context across chats, adhering to user-stated preferences and constraints, and maintaining current information as time progresses. Users can interact with their memory through a dedicated memory summary page, which highlights what ChatGPT knows about them. This feature allows users to review, add, or update information, as well as provide instructions on which topics the model should prioritize or avoid in future interactions.
For instance, users can continue discussions on specific areas of interest, ensuring that ChatGPT remains aligned with their evolving needs and preferences.
Availability of the Update
The Dreaming V3 update is currently available to Plus and Pro users in the United States, with plans to expand access to additional countries and Free and Go users in the coming weeks.
