How we count
Each kind of search both sell is a row, each side at its cheapest product of that kind, because a Google results page and a written answer are not the same purchase. Each price is per 1,000 searches when you make 1,000 or 100,000 searches a month and buy them the cheapest way that provider sells: pay as you go, the plan that covers them with its overage, or a pack spread over the months it lasts. A free allowance is not subtracted; free tiers are listed on their own.
A model's search tool bills the model's tokens on top of each search, so it is compared only with other model tools.
