> best frontier models at effectively unlimited usage.
It would've been easy to spend $5k on Fable in the short week it was available. If that's the direction things are going (we can assume GPT-6 to be if similar class) $5k's not going to get you "best frontier models at effectively unlimited usage".
I know some orgs that are already spending more on tokens than developer salary. That's what unlimited use leads to. Teams of agents running on expensive models, agents designing and running test suites with barely any oversight.
