This is the best sort of correct, in that it’s technically correct. The thing is, We don’t need 5.3 xxhigh reasoning for everything. Giving up some intelligence, and then taking the hit on some inevitable re-runs / re-prompts at 15x ends up with, I bet, more than 37% speed improvement on a lot of tasks.

There’s two ways to run this, and I’m curious which is better (time or quality, either would be interesting) - you could run 5.3xxhigh as the coordinator, spinning up some eager beaver coders that need wrangling, or you could run spark as the coordinator and probably code drafter - where it runs into trouble it could farm out to the big brains.

Now that I think about it, corporations use both models as well. It would be nice for the user if fast coordinator worked well; that lowers turns and ultimately could let you stay in the zone while pairing with a coding agent. But I really don’t know which is better.
