AI doesn't know yesterday's news
Ask AI about yesterday's news and it answers wrong while sounding very sure. The culprit is called the knowledge cutoff.
CUTOFF DATE
The data cutoff
It's the date the training data stops: the last point the model, the AI's brain, learned from.
WHY
Trained first, released later
After training, a model still has to be tested before release, so the cutoff is usually a few months old.
WHAT TO DO
Turn on web search or paste the news
For recent news, turn on web search or paste the article for AI to read, then check the publication date.
This article is based on the video Knowledge cutoff from the Mark học AI channel. Watch the video (in Vietnamese) to see the animations.
