Old information.
WHY
Models are trained to a point in time. Anything after that is unknown.
WHAT THIS AFFECTS
Current prices and specifications Recent events Who holds a position Software versions Anything that changes
WHAT IT DOES INSTEAD OF SAYING IT DOES NOT KNOW
Generates something plausible from what it learned.
That is more dangerous than an admission of ignorance.
WHAT TO DO
Assume anything time-sensitive may be outdated Supply current information yourself Use a tool with search, where available, for current questions Verify anything specific
WHAT TO ASK
"What is your knowledge cutoff?" gives you a rough sense, and treat the answer with the same scepticism as anything else.
FOR SOFTWARE AND TECHNICAL WORK
Version-specific behaviour changes. Generated code may use removed methods.
Check the current documentation.
