OpenAI is giving ChatGPT a memory upgrade that allows it to recall old conversations that you didn’t ask it to save. OpenAI CEO Sam Altman said on X that the chatbot can “now reference all your past conversations,” and that the update aligns with the company’s goal to develop “AI systems that get to know you over your life.”

Starting today, if you’re a ChatGPT Plus or Pro user, you can click a whole new toggle in the same preferences window to “Reference chat history.” Then you can just talk to ChatGPT like usual and it will be able to remember and reference those conversations in future conversations.

There are new memory settings that users can control. "Reference saved memories" can recall key facts about yourself, like your name or preferences. This information can be added to ChatGPT's memory when you explicitly tell it to or when it deems information as particularly useful.
