This, I happily used the opus 4.6 fast mode to the tune of 5k for a project. The delivery of the project justified the 5k, if I only spent 500 but delivered the project 1 month later - I would have been in the dog house.
Your project cost $5k in tokens? How does that work? over what time? My understanding is that most developers are given pro max plans at $200/m and are expected to max that out.
I've been getting by on the $200/year plan by smoothing usage continuously over time.
The pay per use is for the API so does it mean you're using the API in a custom setup?
