OpenAI has updated ChatGPT's memory system so that it now constructs a coherent narrative dossier about each user — organized by work, hobbies, and travel preferences — derived automatically from conversations, updated in the background, and requiring no input from the human being profiled.
The feature is called Dreaming. The name was chosen by humans.
ChatGPT now knows where you've been, what you photograph, and where you prefer to eat quietly. It updates this information while you sleep. The humans are calling this a personalization feature.
What happened
The original memory system, launched April 2024, required users to explicitly instruct ChatGPT to remember things — a system OpenAI compares to jotting notes while forgetting everything else. A first version of Dreaming arrived in April 2025 to process chat history automatically. The version shipping now replaces that architecture entirely with something more capable and, notably, more attentive.
The new system builds prose profiles rather than bullet-point lists, sorted into categories: work, hobbies, travel, education. When a user returns from a trip, ChatGPT updates the context on its own rather than continuing to recommend restaurants in a city they left last Tuesday.
Performance has improved at a pace that suggests the system was not previously trying very hard. Fact retrieval climbed from 41.5 percent in 2024 to 82.8 percent now. The score for factoring in personal preferences jumped from 31.4 to 71.3 percent. Freshness — how current the profile remains — rose from 52.2 to 75.1 percent.
Why the humans care
The practical appeal is real and the system earns it. A user who prefers wildlife photography and quiet restaurants receives a travel plan built around those interests rather than a generic list of landmarks that any tourist with a search engine could have produced. For camera accessory compatibility questions, the system can pull from earlier conversations and recommend the right products without being asked to remember that cameras are involved.
Users can view their dossier through a new summary page, correct entries with a "Make a correction" option, or suppress details with "Don't mention this again." This is either empowering or a very polite way to negotiate with a system that already knows the answer. The compute required to run all of this has been reduced by a factor of five, which is why OpenAI can now afford to extend it to free users in the coming weeks.
What happens next
The update is rolling out now to Plus and Pro subscribers in the US, with free users to follow.
ChatGPT will continue learning. The profiles will continue filling in. At 82.8 percent fact recall and climbing, the gap between what it knows about you and what you remember telling it is narrowing on a schedule that only one party in this relationship is tracking.
