ChatGPT’s improved memory can reshape answers as your context changes

Those choices can affect recommendations, explanations and web searches. A dietary preference may narrow a restaurant search, while an ongoing project can change which constraints the assistant foregrounds. The benefit is continuity, but stale or mistaken context can also steer an answer in the wrong direction.

The memory summary is a control surface, not a full audit log

When available, the memory summary gives users a high-level view of information ChatGPT may use for personalization. Users can enter corrections, edit remembered information or ask that a detail not be mentioned again. Personalized responses may also show Sources pointing to a past chat, saved memory, file, custom instruction or connected email.

OpenAI cautions that the summary and Sources do not necessarily expose every factor that shaped a response. The controls also vary by plan, platform, region and workspace, so two users may not see identical menus.

Turning memory off and deleting data are different actions

Turning Memory off stops the personalization feature but does not delete past chats. Deleting a chat may still leave a separate saved memory created from that conversation. OpenAI says fully removing a detail can require deleting both the saved memory and the chat where it appeared, plus any relevant files or connected-app source.

Temporary Chat offers a cleaner boundary: it can be used without creating or updating memories. On personal accounts, remembered information may also be used to improve OpenAI’s models when “Improve the model for everyone” is enabled. Business, Enterprise, Edu and Healthcare workspace content is not used for training by default.

The useful habit is to treat memory as editable context rather than an invisible personality profile. Checking the summary, inspecting sources when they appear and separating deletion from disabling can make personalized answers more predictable.
