ChatGPT retires GPT-5.2 models and adds memory controls

As announced in OpenAI’s official release notes dated June 12, 2026, GPT-5.2 models — including GPT-5.2 Instant, GPT-5.2 Thinking, and GPT-5.2 Pro — are no longer available in ChatGPT. Conversations previously using these models now continue using the corresponding GPT-5.5 models, which remain fully available. New memory summary controls are now live for all ChatGPT users on the web. Users can delete memories shown on the memory summary page or turn memory off entirely by selecting “Delete and turn off memory” from the three-dot menu. To edit memory content, users may type revisions into the text box at the bottom of the memory summary page or highlight and correct specific text inline. These controls do not delete past chats; re-enabling memory later may generate new memories from retained chat history. Temporary Chats remain unaffected by memory settings: they neither use existing memories nor create new ones. Memory features, including this update, are rolling out across ChatGPT plans and countries — availability may vary by region or subscription tier.
