Seat-based pricing just includes a certain amount of token usage at a discount for buying in "bulk" (and risking not using all your usage). You can still pay the API token-based rates if you really want to; they won't stop you from doing that.
Can you elaborate?
Everyone is talking about the outcome economy and how SaaS should be priced by outcomes and not by seat anymore.
So why aren't the frontier models not working that way yet?
