The big idea
AI learned from the internet up to a certain date. Anything that happened after that date is invisible to the AI.
Some examples
- If AI's cutoff is January 2025, it does not know about June 2025 movies.
- AI may not know who won a recent sports game.
- AI may not know the newest song or app.
- You can ask 'What is your knowledge cutoff?' to find out.
Try it!
Ask AI: 'What is your knowledge cutoff date?' Then ask about something newer than that date.
