FAQ

A background process (first introduced April 2025) that automatically curates ChatGPT's memory by referencing your chat history — synthesizing fresh, relevant context without you saying “remember this.” The June 2026 release is its most capable version, Dreaming V3.

June 4 2026 for Plus and Pro users in the US, rolling out to additional countries and to Free and Go users over the coming weeks.

Three things: carry forward useful context, follow your preferences and constraints, and stay current as time passes. It evaluates each across 2024 (saved memories), 2025 (+ Dreaming V0) and 2026 (Dreaming V3).

A background process learns from many conversations at once and synthesizes a memory state, rather than only writing notes during a single chat. You can review the result in the memory summary page.

OpenAI reports improvements as charts and doesn't publish citable percentage figures in the announcement, so this site doesn't quote any. The one concrete number given is a ~5× reduction in the compute needed to serve dreaming to Free users.

Use the memory summary page to view, add, update and set topic instructions; manage or clear memory in Settings → Personalization → Memory; or use a Temporary Chat that doesn't use or update memory. See OpenAI's Memory FAQ for exact steps.

Memory persists separately from individual chats, so deleting one conversation may not erase what was learned. Treat the Privacy & risks page as general context — for exact policy, rely on OpenAI's Memory FAQ and your regional settings.
