Jev Engineering: use a tiny model as your agent's brain to slash token bills
blaizedsouza · x · 2026-09-24
The author argues that most of an AI agent's spend goes to trivial orchestration decisions—picking the next worker, judging urgency, deciding whether to keep looping—all billed at frontier-model rates. The proposed fix: put a near-zero-cost small model (the "brain") in charge of these millisecond-level routing decisions. The article walks through building your first agent orchestration layer from scratch and claims you can cut most of the agent bill without hurting quality.
