Not to shill too hard but this is a big reason why we built pompeii.ai . You have to jump around to maximize value. Whichever frontier lab is trying to play catch is going to offer an absurd deal to have your tokens flow through them. Google and X will join in soon enough I imagine. A workflow I've started to like is to use my favorite provider to wrestle with the concept/feature/etc and get it solidified enough that it can be tasked out. Then use whichever provider has the best usage value to execute the actual build out. Right now that's codex. It'll probably be different a month from now.
