What agents tools cost to run
20 tools in this category publish a monthly price. The median is $45, from $15 to $900. What follows is what the model underneath would cost at four shapes of work, and what that leaves for everything the company actually built.

The median seat, $45, on the light workload
The same seat price, the same work, three model choices. Nothing about the product changed between those rows. That gap is the reason to ask a vendor which model is underneath and whether it can change without telling you.
