According to Foresight News, OpenAI tweeted that the memory function is now available to all ChatGPT Plus users. Users can start using it by simply starting a new chat window and telling ChatGPT anything they want it to remember. The memory function can be turned on or off in the settings. Currently, this feature is not available in the European and Korean markets. It is expected to be open to teams, enterprises, and GPTs users in the next step.
