OpenAI is rolling out a more capable memory system for ChatGPT that automatically curates and updates context across conversations. This new system, built on "dreaming" architecture, helps ChatGPT remember user preferences and adapt to the passage of time, making interactions more personalized and relevant.

OpenAI is rolling out a more capable memory system for ChatGPT, built on a "dreaming" architecture (V3) that automatically synthesizes and updates memories from chat history. This new system provides fresher, more relevant context by learning from many conversations, evolving beyond earlier memory approaches to be a standalone system.
Initial Availability
Plus and Pro users in the US
Memory Capacity
2x more for Plus and Pro users
Compute Efficiency
5x reduction for Free users
Previous Memory System
Saved memories (April 2024)
User Control
Memory summary page

This update addresses challenges of memory staleness, correctness, and scalability for ChatGPT's hundreds of millions of users. It allows the model to carry forward useful context, follow user preferences (like travel or response preferences), and adapt to the passage of time, reducing the need to re-introduce information.

Users can review and steer what ChatGPT remembers through a memory summary page, where they can add, update, or provide instructions on specific topics. The system is rolling out to Plus and Pro users in the US today, with 2x more memory. It will expand to additional countries and Free and Go users in the coming weeks, with iOS and Android users needing to update their app.

Still wondering? A few quick answers below.

The new ChatGPT memory system is an advanced architecture, called "dreaming V3," that automatically learns and updates information from your conversations. It synthesizes memories in the background to provide fresh and relevant context across all your chats, making interactions more personalized.

Previously, ChatGPT used "saved memories" that required explicit instructions to remember details. An earlier "dreaming V0" supplemented this by curating memories automatically. The new system is a standalone, significantly more capable and compute-efficient architecture that handles memory synthesis autonomously.

The new memory system is rolling out today to Plus and Pro users in the US. It will expand to additional countries and Free and Go users over the coming weeks. Users on iOS or Android need to update their ChatGPT app to the latest version.

You can review and steer what ChatGPT remembers through a dedicated memory summary page. From there, you can see highlights of what the model knows about you, add or update information, and provide instructions on how and when ChatGPT should use specific details.

The term "dreaming" refers to the background process where ChatGPT automatically curates and synthesizes its memory state by referencing chat history. This allows the model to continuously learn and update its understanding of your preferences and context without explicit prompts.
