AI memory

Information an AI chat stores about a user and brings into later conversations. The information is stored with the user's account, outside the AI model that writes the replies, and the chat passes it to that model alongside the user's new messages. The stored information covers details the user asked the chat to remember, material the chat drew from earlier conversations, or both. Replies then build on what the user said in earlier conversations. This stored information differs from parametric knowledge, which the model gained in training and which is the same for every user. A chat that shows ads may also use the stored information to choose them.
