Overview
- OpenAI began rolling out Dreaming V3 on Thursday to ChatGPT Plus and Pro users in the United States with a staged expansion to free and Go users set to follow over the coming weeks.
- Dreaming V3 is a new background memory architecture that synthesizes context across past conversations to reduce stale or incorrect recollections and keep remembered facts current over time.
- Engineers say recent optimizations cut the compute cost of running dreaming by about fivefold, which made it practical to extend the feature beyond subscribers and to double memory capacity for paid tiers.
- The release adds a Memory Summary page where users can review, update, delete or provide instructions about saved information and an option in settings to revert to the legacy saved-memories experience.
- The upgrade builds on April 2024’s saved memories and the April 2025 dreaming system and should make ChatGPT more personalized in daily use while making privacy controls and how memories are used matters for users to monitor.
