If your account shows a memory summary, open Settings → Personalization → Memory, then open the summary’s ••• menu and select Delete and turn off memory. This deletes the remembered information shown in the summary and turns Memory off; it does not delete your chats. (OpenAI Help Center: Memory in ChatGPT)
Delete memories in ChatGPT
If you see a memory summary
- Open Settings.
- Select Personalization, then Memory.
- Open the memory summary and select its ••• menu.
- Select Delete and turn off memory.
- If ChatGPT presents a confirmation prompt, follow it. Then check the Memory settings to see whether Memory is off.
OpenAI describes this action as deleting the remembered information shown in the summary and turning Memory off. The summary is a high-level view; it may not include every detail or source Memory can reference. (OpenAI Help Center: Memory in ChatGPT)
If you see a saved-memories list
Open Settings → Personalization → Memory and look for Manage or Saved memories. OpenAI’s guidance says the available controls can differ by memory experience. The source material available for this guide does not establish the exact delete-one or clear-all button labels for this list, or whether switching off Reference saved memories preserves existing entries. So don’t assume that turning the setting off deletes stored entries: use the delete controls shown in your account for an individual memory, and follow any confirmation shown. If you cannot identify a clear-all control, consult the Memory settings guidance linked above rather than assuming that turning Memory off clears the list.
Correct one detail instead
If you use the summary interface and want to correct a detail rather than clear all the information shown, OpenAI’s guidance describes entering a correction or highlighting text in the summary and providing a correction. The summary may not show every detail or source Memory can reference. (OpenAI Help Center: Memory in ChatGPT)
What deleting Memory does—and does not—remove
Deleting the remembered information shown in the summary does not delete past chats. If Memory is turned on again, ChatGPT may create new remembered information from chats that remain in your history, including older chats. (OpenAI Help Center: Memory FAQ)
If you want to remove a detail from the sources where it appears, OpenAI’s guidance is to delete each relevant source. Depending on where the detail is stored, that may mean deleting the relevant chat (including an archived chat), removing the detail from Memory, or disconnecting a connected app that contains it. (OpenAI Help Center: Memory FAQ)
Files can be stored separately from chats. Deleting a chat does not delete a separately saved file; delete that file from Library or Space if you also want to remove that copy. (OpenAI Help Center: Chat and file retention in ChatGPT)
Does this apply to a production model API?
No—not as a way to delete consumer ChatGPT memories. The steps above are for ChatGPT’s product settings. The OpenAI API has separate conversation-state resources for developers, including a Conversations API delete operation; its reference says deleting a conversation does not delete the items in it. That API operation is not documented as a control for a person’s ChatGPT memory summary or saved memories. (OpenAI API: Delete a conversation; OpenAI API: Conversation state)
