OpenAI Rolls Out Dreaming V3 to Supercharge ChatGPT Memory, Doubling Recall to 82.8%

OpenAI has deployed Dreaming V3, a major overhaul of ChatGPT's memory system that automatically synthesizes user context across conversations, improving factual recall from 68% to 82.8% while cutting compute requirements by five times. The upgrade, which reached Plus and Pro subscribers in the US in June 2026, represents a shift from manual "saved memories" to an autonomous background process that reads across years of chat history to build dynamic user profiles.
