Overview
- OpenAI began a staged rollout to Plus and Pro users in the United States on June 4, 2026, replacing explicit saved notes with a more capable dreaming-based memory system.
- Paid users gain twice the prior memory capacity as the system automatically synthesizes and preserves relevant details from past chats.
- A new memory summary page lets users view highlights of what ChatGPT knows, edit or add details, and give instructions about when the assistant should use stored information.
- OpenAI says it cut the compute cost of serving dreaming by roughly 5x, which it plans to use to bring a compute-optimized version of dreaming to Free users over the coming weeks.
- The update responds to past problems with memory—staleness, incorrect recall, and poor scalability—and builds on the April 2024 saved-memories feature and earlier dreaming experiments to evaluate memory by usefulness, preference-following, and timeliness.
