OpenAI introduced a dreamy memory update for ChatGPT: "a significantly more capable and compute-efficient memory architecture built on top of dreaming"

"In contrast to saved memories, dreaming leverages a background process that allows ChatGPT to learn from many conversations and synthesize ChatGPT’s memory state in order to always provide the freshest, most relevant context to your conversations. Dreaming also makes it easier for memory to include context that occurs naturally in conversation, without relying on explicit requests to remember something."

Rolling out to Plus and Pro users in the U.S. Free, Go & more countries will get the memory upgrade over the next several weeks.
