ChatGPT Rolls Out Dreaming V3 Memory to Plus, Pro Users as 5X Cheaper Profiling Raises Concerns

Summary
Dreaming V3 is now live for ChatGPT Plus and Pro users, with a broader rollout to free users planned in coming weeks; the upgrade builds a synthesized profile from past chats, preferences and inferred behavior.
OpenAI says the system is 5X cheaper to run and has sharply improved recall metrics, with factual task recall rising to 82% in 2026 from 41% in 2024 and long-term correctness to 75% from 9%.
The feature also raises accuracy concerns because it can infer details not explicitly stored and get them wrong; ZDNET showed ChatGPT claiming experience with Home Assistant that the user said never happened.
Memory controls appear limited: turning memory off does not remove stored memories or chat history, and fully purging some information may require deleting the underlying chats, while safety-related context can still be retained.
The rollout expands a memory system introduced in 2024 from saved facts into ongoing background synthesis, intensifying privacy worries that old or irrelevant conversations could skew future answers and create a persistent user dossier.
