OpenAI's Dreaming V3 makes ChatGPT memory fully automatic, extending it to free-tier users
Dreaming V3, rolling out to US Plus and Pro users since June 4, replaces ChatGPT's manual saved-memories list with a background process that synthesizes a user profile across years of past conversations and updates it over time — no user action required. The 5x compute reduction enabling the free-tier expansion comes with a structural consequence: synthesized memories live in a separate data layer, survive conversation deletion, and are injected into every new session's system prompt — the same architecture Tenable Research identified in 2025 as a prompt-injection exfiltration channel that OpenAI has not confirmed Dreaming V3 addresses. The rollout lands eight weeks before EU AI Act chatbot transparency obligations take effect on August 2, 2026.

a maliciously crafted prompt injected through a third-party source can instruct ChatGPT to update persistent memory, creating an exfiltration channel that survives across sessions.
Why this matters
- → Automatic memory synthesis now reaches 500M+ free users, expanding behavioral profiling at scale.
- → Separated memory layer survives conversation deletion and creates prompt-injection exfiltration risk OpenAI ha
- → Launch precedes EU AI Act transparency deadlines by 8 weeks, raising compliance timing questions.
