ChatGPT Temporary Chat: History, Memory, Training and Deletion Explained

4 min read
An enormous black-and-white photograph of an open ring-binder stands upright in the middle of the frame, scaled as though it were a wall.

Quick answer: ChatGPT Temporary Chat stays out of your chat history unless you choose to save it. While it remains temporary, OpenAI says it is not used to improve its models and does not create or update memories. OpenAI may retain a copy for up to 30 days for safety. Temporary does not mean that no data is processed or that every feature has the same privacy boundary.

Temporary Chat now has a detail many older guides miss: you can choose Personalized or Unpersonalized before sending the first message. A personalized temporary chat can use existing memories, custom instructions and plugins. An unpersonalized one does not use those features. Neither option creates new memories while the conversation remains temporary. These distinctions come from OpenAI's current Temporary Chat guide.

How do you start a Temporary Chat?

  1. Open a new chat in ChatGPT.
  2. Select Temporary.
  3. Choose Personalized or Unpersonalized before your first message.
  4. Enter your prompt only after reviewing that choice.

The precise button placement can vary by app and device. The important step is to check the mode before sharing information, since OpenAI says the personalization choice cannot be changed after that chat begins. Account and workspace restrictions still take priority over an individual chat's choice.

What happens to history and memory?

An unsaved Temporary Chat does not appear in normal chat history, and you cannot reopen it from history after leaving it. That makes it useful for a one-off question you do not want to keep in your sidebar. A personalized temporary chat may read existing memories to tailor its answer, but does not add new memories while temporary. If you want the least personalization, choose Unpersonalized before starting.

OpenAI also notes a narrow safety exception: safety systems may use limited relevant context from prior conversations in rare, high-risk situations. For that reason, “Unpersonalized” should be read as a setting for normal personalization features, not as an absolute promise that no earlier context can ever be consulted.

Are Temporary Chats used for training?

OpenAI says a chat is not used to improve models while it remains temporary, whether personalized or unpersonalized. If you save it to your history, it becomes a regular chat. From that point, your account's model-improvement setting and workspace policy apply. The distinction is especially important if you routinely save conversations after working through a problem.

If your goal is to keep normal history but disable model training, Temporary Chat is not the only option. OpenAI says personal-workspace users can go to Settings, Data Controls, then turn off “Improve the model for everyone” for new chats. Business, Enterprise and Edu defaults differ; consult your workspace policy rather than assuming a personal-account setting applies to a team.

How long is a Temporary Chat kept?

OpenAI's retention guide says it may keep a copy of a temporary chat for up to 30 days for safety. Saving the chat changes it into a regular one, with regular retention rules. Deleting a saved chat removes it from the account view immediately, but OpenAI schedules permanent deletion within 30 days, subject to stated exceptions such as legal or security obligations.

Files deserve separate attention. OpenAI says eligible uploaded files may also be saved to Library when you save a Temporary Chat, where Library is available. Deleting a chat does not necessarily delete a separate Library copy. If you need a file gone from both places, review Library as well as the conversation.

When is it useful, and when is it insufficient?

Use Temporary Chat for a quick brainstorming or explanation task that you do not intend to revisit. Choose Unpersonalized when you do not want existing memories or instructions to shape the answer. For confidential customer records, employee files or trade secrets, first follow your organization's approved tools and data policy. A temporary user interface does not replace permission to share that data with a service.

If you use a GPT that sends data to an external action, OpenAI says the third-party recipient's privacy policy governs data sent to it and may allow longer retention. That is a separate boundary from ChatGPT's temporary-history setting. Look at the action before providing sensitive content.

Frequently asked questions

Does Temporary Chat use my memories?

It can use existing memories if you choose Personalized. Choose Unpersonalized before the first message to avoid normal memory-based personalization.

Can I save a Temporary Chat later?

Yes. Saving converts it to a regular chat and changes which account data settings apply from that point on.

Is Temporary Chat immediately deleted?

No. OpenAI says it may retain a copy for up to 30 days for safety.
