OpenAI is introducing a significant updated memory system for ChatGPT called Dreaming, starting with Plus and Pro users in the United States.
The update improves how ChatGPT It remembers context between conversations, follows user preferences, and updates its memories over time. Free and Go users will gain access over the coming weeks as the rollout continues internationally.
The update is the third major release of ChatGPT’s memory feature since its initial release in April 2024.
How ChatGPT memory has changed from saved memories to Dreaming V3
The original Saved Memories system, released in April 2024, required users to explicitly tell ChatGPT to remember information.
In April 2025, the first version of Dreaming was introduced, which added a background process that automatically synthesized memories from chat history instead of relying on explicit save commands.
The latest Dreaming V3 is a more capable and efficient architecture built on that foundation. OpenAI says recent improvements have reduced the compute required to offer Dreaming to free users by approximately five times, allowing for broader deployment.
What Dreaming V3 improves
OpenAI evaluates memory quality in three key areas and reports the following success rates across different memory versions:
Fact recall, which involves remembering specific information shared by the user:
- 2024 memories saved: 41.5%
- 2025 Dreaming V0: 67.9%
- 2026 Dreaming V3: 82.8%
Preference compliance, that is, the system’s ability to follow dietary, behavioral and personal restrictions:
- 2024: 31.4%
- 2025: 55.3%
- 2026: 71.3%
Stay current by updating memories as circumstances change:
- 2024: 9.4%
- 2025: 52.2%
- 2026: 75.1%
The most notable progress occurs in time awareness. Previous memory systems could become obsolete, such as continuing to treat a past trip as continuous after the user returned home. Dreaming V3 automatically updates memories to reflect the passage of time.
Memory summary page, user controls and privacy settings
Users can now see what ChatGPT has stored about them on a new memory summary page. This page provides a simple overview of the information held, including work, hobbies, travel, and preferences.
Users have the option to add or correct details directly or instruct ChatGPT on which topics to focus on or avoid. Individual memories can be deleted at any time and users can choose to disable the memory completely through settings.
ChatGPT’s memory system offers several controls:
- Users can view all generated memories from the memory summary page.
- Individual memories can be removed upon request.
- Memory can be completely disabled in settings.
- Temporary chats do not use or refresh memory.
OpenAI also notes that conversations involving connected financial accounts, part of the recently introduced Finance feature, follow separate memory rules and can be managed independently.
Dreaming V3 is now available for Plus and Pro users in the United States. Over the next few weeks, it will expand to other countries and will be available to Free and Go users. OpenAI has not provided specific dates for the broader release.
