Believe it or not, this is not the first robotaxi-assisted theft.

OpenAI is rolling out some significant enhancements to ChatGPT’s memory feature, particularly if you’ve been using the chatbot through a free account. Before getting to those improvements, a quick recap will help set the stage for what to expect: OpenAI shipped its first memory feature in April 2024. By the company’s own admission, this early implementation, then known as saved memories, was basic. It depended on strong cues from user, such as a direct prompt telling ChatGPT to remember a fact. People also found the chatbot’s memories became less relevant over time. So over the next year, OpenAI began working on the first version of a feature it would end up calling dreaming. 

Dreaming runs in the background, allowing ChatGPT to synthesize information from many different conversations without it relying on explicit instructions to remember something. “Over the last year, dreaming supplemented saved memories to create a step-function improvement in ChatGPT’s ability to personalize responses and offset the staleness of saved memories,” OpenAI explains. “However, it historically was never sufficient as a standalone memory system.”

That brings us to today’s release, which sees OpenAI rolling out what it describes as a new memory architecture that builds on the dreaming process to offer something that is “significantly” more capable and compute-efficient. Now, as ChatGPT synthesizes information about you, it will write a “memory summary” you can read at any time. From there, you can add and update information about yourself, as well as tell ChatGPT when it should reference what it knows about you and your preferences. “If you want to drill down into a particular area to learn more, just chat with the model,” says OpenAI. The new summary is designed to complement the memory sources feature OpenAI released alongside GPT-5.5 Instant. Sources allow you to see the information ChatGPT used to personalize an answer, and edit or delete that context as desired. You can see both features pictured above.

Besides offering greater visibility to the user, OpenAI says the new dreaming architecture is better at carrying forward context. For example, if you’ve talked to ChatGPT about photography in the past and mentioned the camera you currently use, the chatbot will know to generate tailored results the next time you ask for product recommendations that are compatible with your photography setup.

Similarly, OpenAI says the new architecture is better at following preferences. Say you’re planning a trip, ChatGPT will use things it has learned from past travel conversations to inform its responses. Using photography as example again, it might suggest a Singapore itinerary that includes suggestions on spots where you can do street photography. To bring everything together, ChatGPT will automatically revise its memories as time passes, so that it doesn’t do something like reference a trip you took in the past as if it were coming up.

OpenAI is beginning to roll out the new memory architecture to Plus and Pro users in the US starting today. Thanks to behind-the-scenes efficiency improvements, ChatGPT will, for the first time, soon start recording memories through the dreaming process for free accounts. As a Plus or Pro user, those enhancements will translate to ChatGPT offering greater memory capacity. The new architecture will roll out to users in other countries in the coming weeks.

Mira Murati isn’t a natural creature of the conference stage. As the CTO of OpenAI, she was present but rarely the public face of the company. As CEO of her own company, Thinking Machines Lab, she has been even harder to find. So when she sat down with Bloomberg in San Francisco on Thursday — her first major media appearance in roughly 18 months — it was worth paying attention, even if she was careful not to say too much.

The timing makes sense. Thinking Machines has spent the better part of a year and a half operating largely in the background: raising capital, hiring researchers, and shipping one product, Tinker, an API for fine-tuning open-source AI models.

In the meantime, the companies competing for the same talent, customers, and headlines have only grown more omnipresent. OpenAI, where Murati spent six years as CTO, is constantly in the news cycle. Anthropic’s momentum is all that anyone can talk about right now. And xAI, Elon Musk’s AI venture, has been folded into SpaceX ahead of what is expected to be its massive public offering, generating its own gravitational pull on attention and investment. In that environment, staying heads down has diminishing returns; at some point, you have to make some noise just to remind the market you exist.

Murati used the Bloomberg appearance to do exactly that and not much more. She previewed what Thinking Machines is calling “interaction models,” which she described as a fundamentally different kind of AI interface. Rather than the turn-based, prompt-and-response dynamic that defines most AI products today, she told interviewer Emily Chang, the company’s models are designed to process continuous streams of audio, text, and video in 200-millisecond intervals. The idea is that they can pick up on the texture of human communication — the interruptions, the mid-thought corrections, even pauses to think — in something closer to real time. But Murati was careful to frame it as a first step, not a finished product, and she declined to put a specific release date on anything.

She also answered questions about the episode that first put her more squarely in the public eye: the chaotic week in November 2023 when OpenAI’s board fired Sam Altman and she became interim CEO. Inside OpenAI it came to be called “the blip.” Murati said she felt clear about her decisions in each moment — that protecting the mission and the team was the through-line that made the choices feel obvious even as the situation appeared to be falling apart from the outside. She said the company would have “imploded” if not for her involvement through that strange five-day stretch and its immediate aftermath. But she acknowledged that clarity of intent is not the same thing as clarity about consequences. In retrospect, she said, she would have pushed harder for more information, a better transition plan, and more transparency. What she did not say, at least not directly, is whether she thinks things turned out well.

Asked whether she still trusts her former boss, she sidestepped the question, steering the conversation toward a larger concern that she returned to several times: the concentration of consequential decisions in too few hands — not just at OpenAI but across the industry. Her worry, she said, is less about the character of any individual leader (though she acknowledged that matters) and more about the absence of structural checks. Good people make bad calls. Well-intentioned organizations drift. Too much attention has been paid to virtue and too little to governance, she suggested.

Chang also politely pressed her on the departures of several high-profile researchers from Thinking Machines in recent months , a subject Murati has largely avoided in public and that she downplayed on Thursday. First, she said, building a frontier AI lab from scratch compresses years of normal organizational volatility into months. She also acknowledged that compensation — the nine-figure packages that have become standard currency in the war for AI talent — captures people’s imaginations, but she suggested it isn’t usually the whole story. To some audience laughter, she said of her own competitive instincts, “When I wake up in the morning, I am not thinking about how to kill the competitor.”

Naturally, Chang asked about what comes next for AI broadly, including for the humans who AI companies once said would be empowered by AI but who’ve more recently grown scared by talk of mass job displacement, not to mention a future where AI is used to create chemical weapons.

Murati, who was born in Albania and speaks with a slight Eastern European accent, was measured in her response. She pushed back on the framing of inevitable dystopia or inevitable utopia, arguing that neither outcome is predetermined and that the period we’re in right now is the one that will determine which way things go. Still, she said — and not for the first time during the interview — that if humans take their hands off the wheel too soon, the future will look very different, and not better.
