OpenAI Launches Dreaming V3 for ChatGPT Memory — Background Synthesis Replaces the Saved-Memories List, Internal Factual-Recall Eval Jumps From 41.5% to 82.8%, and a 5× Compute Cut Opens the Door to Free-Tier Rollout
OpenAI's new memory system runs background synthesis after each chat to build and update user profiles without 'remember this' prompts. About 5x less compute per user lets it reach Plus and Pro in the US today, free users in the coming weeks.
ChatGPT's memory finally runs in the background — no more 'remember this' prompts, with free-tier rollout queued behind a 5x compute cut.
Key specs
| Factual recall 2024 | 41.5% |
|---|---|
| Factual recall 2025 | 67.9% |
| Factual recall 2026 | 82.8% |
| Preference adherence | 71.3% |
| Currency over time | 75.1% |
| Compute reduction | 5x |
| Paid memory capacity | 2x |
What is it?
Dreaming V3 is OpenAI's third-generation memory architecture for ChatGPT. It replaces the old saved-memories list with an automatic background process that synthesizes preferences and facts from every conversation, surfaces them in an editable summary, and updates them as time passes.
How does it work?
After each chat, a background pipeline pulls salient context into a structured memory state — preferences, ongoing projects, time-sensitive facts. The system rewrites stale entries ('going to Singapore in July' becomes 'went to Singapore in July 2026') instead of accumulating them. Plus and Pro users get 2x the prior memory capacity. OpenAI says compute per user dropped roughly 5x, which is what made the free-tier rollout feasible.
Why does it matter?
ChatGPT's earlier memory was opt-in and shallow — it stored what you explicitly told it to store and little else. Dreaming V3 makes long-running personalization the default, so chats from months ago can shape today's answers without manual bookkeeping. OpenAI's internal evals show factual recall climbing from 41.5% in 2024 to 82.8% in 2026, preference adherence at 71.3%, and currency over time at 75.1%.
Who is it for?
