OpenAI has rolled out one of the biggest upgrades ever to ChatGPT, enabled the AI model to tap into your entire conversation history to provider a more customized experience.

ChatGPT is able to “remember” certain details about you, which it can use to improve interactions. In a post on X, OpenA says it is now expanding ChatGPT’s access to conversation history, making the entire history available.

The company says this will result in more relevant and useful responses.

In addition to the saved memories that were there before, it can now reference your past chats to deliver responses that feel noticeably more relevant and useful.

New conversations naturally build upon what it already knows about you, making interactions feel smoother and uniquely tailored to you.

OpenAI says users can still control what conversations are used, as well as whether memory is enabled at all.

As always, you’re in control of ChatGPT’s memory. You can opt out of referencing past chats, or memory altogether, at any time in settings.

If you’re already opted out of memory, you’ll be opted out of referencing past chats by default.

If you want to change what ChatGPT knows about you, simply ask in chat.

If you’d like to have a conversation without using or affecting memory, use temporary chat.

The new feature is rolling out today to users worldwide, with the exception of “the EEA, UK, Switzerland, Norway, Iceland, and Liechtenstein.”
