· Updated

OpenAI is rolling out an enhanced memory system for ChatGPT that automatically synthesizes and updates user preferences, constraints, and conversational context. This new architecture, built on "dreaming," allows ChatGPT to provide more personalized and continuous interactions, with users able to review and manage what it remembers.

ChatGPT is rolling out a more capable ChatGPT memory system, built on its "dreaming" architecture, to enhance personalization and continuity. This update moves beyond explicit "saved memories" (April 2024) by automatically curating and updating context from chat history, addressing staleness and scalability.

Still wondering? A few quick answers below.

The new memory system for ChatGPT is built on a "dreaming" architecture that automatically curates and updates memories from your chat history. It enhances personalization and continuity by learning your preferences and context over time, moving beyond older "saved memories."

ChatGPT's memory evolved from "saved memories" in April 2024, which required explicit instructions. In April 2025, the first version of "dreaming" was introduced to automatically curate memories. Today's update is a significantly more capable and compute-efficient "dreaming" V3 architecture.

You can control ChatGPT's memory through a new memory summary page. This page allows you to review the highlights of what ChatGPT knows about you, add or update information, and provide instructions on what topics it should bring up.

The update improves ChatGPT's ability to carry forward useful context, follow your preferences and constraints, and stay current as time passes. It leads to more personalized responses and reduces the need to reintroduce yourself or your ongoing projects.

The new memory system is rolling out starting today for Plus and Pro users in the US. It will expand to all users, including Free and Go tiers, and additional countries over the coming weeks.
