OpenAI is introducing a significantly upgraded memory system for ChatGPT called Dreaming, starting with Plus and Pro users in the United States.
The update enhances how ChatGPT remembers context between conversations, follows user preferences, and updates its memories over time. Free and Go users will gain access over the next few weeks as the rollout continues internationally.
The update is the third major version of ChatGPT’s memory feature since its initial launch in April 2024.
How ChatGPT’s Memory Has Changed From Saved Memories to Dreaming V3
The original Saved Memories system, launched in April 2024, required users to explicitly instruct 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 states that recent improvements have reduced the compute needed to serve Dreaming to free-tier users by about five times, enabling a broader rollout.
What Dreaming V3 Improves
OpenAI evaluates memory quality across three key areas and reports the following success rates across different memory versions:
Factual recall, which involves remembering specific information shared by the user:
- 2024 saved memories: 41.5%
- 2025 Dreaming V0: 67.9%
- 2026 Dreaming V3: 82.8%
Preference adherence, meaning the system’s ability to follow dietary, behavioral, and personal constraints:
- 2024: 31.4%
- 2025: 55.3%
- 2026: 71.3%
Staying current by updating memories as circumstances change:
- 2024: 9.4%
- 2025: 52.2%
- 2026: 75.1%
The most notable progress is in time awareness. Earlier memory systems could become outdated, such as continuing to treat a past trip as ongoing after the user returned home. Dreaming V3 automatically refreshes memories to reflect the passage of time.
Memory Summary Page, User Controls, And Privacy Settings
Users can now view what ChatGPT has stored about them on a new memory summary page. This page offers a simple overview of retained information, including work, hobbies, travel, and preferences.
Users have the option to add or correct details directly or give ChatGPT instructions on which topics to focus on or avoid. Individual memories can be deleted at any time, and users can choose to disable memory entirely through the settings.
ChatGPT’s memory system offers several controls:
- Users can view all generated memories from the memory summary page.
- Individual memories can be deleted on demand.
- Memory can be turned off completely in the settings.
- Temporary chats do not use or update memory.
OpenAI also notes that conversations involving connected financial accounts, part of the recently introduced Finances feature, follow separate memory rules and can be managed independently.
Dreaming V3 is now available to Plus and Pro users in the United States. Over the next few weeks, it will be expanded to other countries and made available to Free and Go users. OpenAI hasn’t provided specific dates for the wider rollout.
