OpenAI rolls out advanced 'dreaming' memory system to Plus and Pro users

OpenAI has begun rolling out a significantly more capable and compute-efficient memory architecture—built on a technique called 'dreaming'—to ChatGPT Plus and Pro subscribers in the US. The update promises a more scalable system for synthesizing conversation memory, including a new memory summary feature for users.

According to TestingCatalog, OpenAI is launching a new memory system that it claims is both more capable and more compute-efficient than its predecessor. The feature, described as being "built on top of dreaming," is being rolled out to ChatGPT Plus and Pro subscribers in the United States.

The company says the new architecture provides a "significantly more capable and scalable system for synthesizing memory." Users will reportedly be able to access a memory summary, suggesting a more transparent or structured approach to how the model retains context across conversations.

The update marks a notable product enhancement for paying subscribers, though OpenAI has not yet disclosed detailed technical documentation on how the underlying "dreaming" mechanism functions under the hood.
