ChatGPT Dreaming V3: OpenAI's New Memory System Explained

OpenAI is rolling out a new ChatGPT memory system called Dreaming V3. This update replaces the old way of saving memories with an automatic background process. It reads past conversations and updates what the system remembers about a user without any prompting. This new system began reaching Plus and Pro subscribers in the United States on June 4th. Free, Go, and international users will get it in the coming weeks. Previously, memory relied on a list of saved facts and an older background process. Dreaming V3 combines these into one system that synthesizes memory from many conversations at once. It automatically captures context and updates existing memories. For example, a memory about an upcoming trip to Singapore will update after the trip occurs. This memory state is stored separately from conversation logs. It's injected into the system prompt for every new conversation. This means deleting a conversation does not remove memories derived from it. To fully remove a detail, users must delete both the memory entry and the original conversation. Even then, logs of deleted memories may be kept for up to 30 days. This change means ChatGPT will know more about its users, and managing this knowledge requires more attention than before.
