I also use it this way and I'm overall pretty happy with it, but it feels like they really
want us to use it in "autopilot" mode. It's like they have two conflicting priorities of "make people use more tokens so we can bill them more" and "people are using more tokens than expected, our pricing structure is no longer sustainable"
(but I guess they're not really conflicting, if the "solution" involves upgrading to a higher plan)
