Router.

Cut spend without cutting outcomes.

Router is the optimizer. It watches what Observe knows about quality per model per task, then routes each call to the cheapest model that holds the outcome bar. Spend drops, outcomes stay, and every reroute is logged and reversible.

The controls

What it controls.

Routes to cheaper models only where measured quality holds. Outcomes set the bar, not vibes.

02
Spend simulation

Preview the savings before enabling. Per task type, per team, per model.
