OpenAI is rolling out a major upgrade to ChatGPT's memory architecture. The new system, built on a technique called 'dreaming,' improves how the AI recalls and applies user preferences over time. A new memory summary page lets users review, update, or correct what ChatGPT remembers.
New memory summary page gives users control
The upgrade is available to ChatGPT Plus and Pro subscribers in the US starting today. A wider rollout across other regions is expected in the coming weeks. The update is designed for users who depend on ChatGPT for tasks that require ongoing context and consistency.
OpenAI's internal evaluations show significant gains. Factual recall jumped from 67.9% in 2025 to 82.8% in 2026. Preference adherence improved from 55.3% to 71.3%. Accuracy over time rose from 52.2% to 75.1%.
Dreaming architecture boosts accuracy over time
The memory summary page is a key addition. Users can see a list of facts and preferences ChatGPT has stored. They can delete incorrect entries or add new ones directly. This provides users with greater control over the AI's long-term behavior.
The upgrade builds on earlier memory features introduced in 2025. Earlier capabilities let ChatGPT remember details across sessions but provided limited transparency. The new architecture aims to make memory more reliable and editable.
OpenAI says the improvements come from a redesigned memory system that uses 'dreaming' to consolidate information. The company has not detailed how dreaming works technically. The feature is being deployed as a server-side update, so no app download is needed.
For now, the upgrade is limited to US users on paid plans. OpenAI has not announced pricing changes or a timeline for free-tier access. The company says wider availability will follow in the coming weeks.
