Dreaming: Better memory for a more helpful ChatGPT

ChatGPT is rolling out an advanced memory synthesis system to improve user experience. This system addresses previous limitations like staleness and scalability in handling memory across millions of users and extended timeframes. The core idea is to allow ChatGPT to learn user preferences, projects, and constraints, ensuring future conversations build upon shared context rather than starting anew. This significantly enhances ChatGPT's usefulness by fostering deeper understanding and enabling it to assist users in achieving long-term goals.

This new system, built upon a concept called "dreaming," represents a substantial upgrade from earlier "saved memories" functionality. While saved memories relied on explicit user instructions and often became outdated, "dreaming" operates in the background, automatically curating memories from chat history. This allows ChatGPT to continuously synthesize and provide the freshest, most relevant context without requiring direct user input. It also facilitates the inclusion of naturally occurring conversational context, leading to more fluid and intuitive interactions.

Users can review the memories synthesized by "dreaming" through a memory summary page. This feature enables quick access to highlights of what ChatGPT knows, allows users to update their information, and provides control over topics ChatGPT should bring up. This transparent management empowers users to refine their personalized ChatGPT experience.

The update is currently available to Plus and Pro users in the US, with plans for a broader rollout to additional countries and Free and Go users in the coming weeks. This phased release ensures a smooth transition and continuous improvement of this critical feature.
