Every AI answer is paid for in tokens.
DailyTech.ai explains AI news, models and tools with the numbers that decide them: tokens, context, price and speed.
An estimate for English text: real tokenizers differ by model, often by 10 to 20 percent. A page here means about 500 words.

How we check
Numbers come with a source
Prices, context sizes and benchmark scores link to the provider's own page, with the date we read it.
We say what we did not test
When a result comes from someone else's test, we name them. We do not present other people's work as ours.
Corrections stay visible
When a fact changes or we get one wrong, the article says what changed and when.
