How usage units work
Usage units measure AI activity during an active service pass.
Every AI request uses usage units based on how much work the AI performs.
Ask shorter questions when you want your usage units to last longer.
Every time you ask AI to do something, a small number of usage units are used.
Simple questions use fewer usage units.
Bigger tasks like writing long documents, analysing files, coding help, or image generation use more usage units.
You'll always see how many usage units were used and how many remain in your active service pass after each request.
