ChatGPT's memory just got a major architectural overhaul. OpenAI is rolling out a new system called Dreaming V3, which replaces the old approach of jotting down facts you explicitly asked it to remember with a background process that synthesizes context from your conversations and keeps that context fresh as time passes.

The goal is to tackle the staleness, correctness, and scalability challenges that show up when memory is applied to hundreds of millions of users and multi-year time horizons in ChatGPT. In practice, that means ChatGPT should stop forgetting things you mentioned offhand months ago, and stop confidently telling you about your trip to Singapore weeks after you got home.

Who gets it and when

The update is available to Plus and Pro users in the US today, and will roll out to additional countries and Free and Go users over the coming weeks. Plus and Pro users get 2x more memory as part of the rollout. To turn it on, update the ChatGPT app on iOS or Android. If you prefer the legacy saved memories experience, you can switch back in settings.

From sticky notes to a living profile

To understand why this matters, it helps to know how ChatGPT memory has evolved. Memory first launched in April 2024 as saved memories, which required explicit user instructions to store information. OpenAI introduced the first version of dreaming in April 2025, allowing ChatGPT to reference chat context beyond the saved memories list.
