Changed

  • Your Year with ChatGPT
  • Today we’re rolling out Your Year with ChatGPT, an optional, personalized end-of-year experience that reflects on how you interacted with ChatGPT in 2025. It highlights high-level themes from your conversations and includes summary statistics about your usage over the year.
  • To see Your Year with ChatGPT, Memory and Reference Chat History must be turned on, and you must meet a minimum activity threshold. If you have very limited activity, you’ll only see basic chat statistics.
