Drop in. Route smart. Cut costs.

Most agent loops pin one expensive model across every step, from planning to retrieval to tool calls to synthesis to verification, and pay frontier prices throughout. IQ Routing classifies each step and sends it to the cheapest model that still holds quality, then serves repeats from cache instead of billing you twice. The same session carries an audit trail of every model call, a capability resolver so you name intent instead of pinning models, and a cost envelope that caps spend before a runaway loop blows the budget.
