Recent discussions have emerged regarding the capabilities of ChatGPT, particularly its memory function. Users have noted that if memory is not activated, ChatGPT does not retain past interactions, leading to misconceptions about its ability to recall personal information. Some users suggested a playful activity where individuals ask ChatGPT to create a portrait based on their interactions. However, experts clarified that this only works if the memory feature is enabled and contains accurate data. Without memory, ChatGPT generates responses without any personal context, effectively making up information. This has raised concerns about the understanding of how large language models (LLMs) operate in relation to user data.
