Smart model in charge, planning & orchestrating the dumb models doing the work.

Often dumb models from other plans & subscriptions. I like to choose whatever model is on sale on opencode-go.

YMMV drastically based on what the actual work is. Dumb models can't handle everything. And of course I have no idea how much of a backlog of work you're feeding it or anything. Some people have enough work to exceed any plan, and do the work inefficiently to boot.

Also, you can just buy as much usage as you want at API rates.
