The problem
You ask Claude to research 20 prospects, and the frontier model reads all 20 pages itself, writes up all 20 summaries itself, and burns through your usage limit before lunch. It's the same brain doing the planning and the busywork, at the busywork's expense. So you either slow down to stretch the tokens, or you pay for a bigger plan to keep doing the same wasteful thing faster.
The outcome
We set up your Claude so the frontier model runs the show instead of doing every task itself. Say you need those same 20 prospects researched: Fable plans the search and decides what a good result looks like, twenty Sonnet subagents each read one prospect and report back, and Opus handles the two writeups that need real judgment. Fable only touches a few thousand tokens instead of doing all twenty reads itself. You get the research done, at the quality you'd expect, without watching the meter run out.
