ChatGPT Dreaming

Dreaming is the memory architecture in ChatGPT that learns from many past conversations in a background process and synthesizes a current memory state, rather than relying only on notes saved during a chat. OpenAI says a first version appeared in April 2025 alongside saved memories (introduced April 2024). The June 2026 update, described as Dreaming V3, is presented as a more capable and compute-efficient system built to address staleness, correctness and scalability problems at large user scale and over multi-year histories.

Dreaming lets ChatGPT pick up context that occurs naturally in conversation without an explicit "remember this" request, and it accounts for the passage of time (for example, a planned event that has since passed). Synthesized memories can be reviewed through a memory summary page, where users can see highlights, add or update information, and give instructions on which topics ChatGPT should bring up and when.

It is a feature inside the ChatGPT app, not a separate product. At announcement on 4 June 2026 it was available to Plus and Pro users in the US, with rollout to additional countries and to Free and Go users planned over the following weeks. Creators noted larger memory for paid tiers. Details of limits and EU rollout timing are not given in the provided material.
