Specialist AI brains — one question, one answer

ONE QUESTION.

MANY EXPERTS.

Ask anything once. Icaruz sends it to specialist brains — security auditors, framework experts, domain researchers — and combines their answers into one clear response. Run the same question again and you pay less, not more.

Expert networks shouldn't
rebill context

Multi-expert agents fan out to N brains in parallel. Each call resends the same wiki articles as context — standard gateways bill that prefix N times. Icaruz separates stable wiki context from the volatile user question so BTL Runtime can cache, dedupe, and prove savings.

Not a base-URL swap. We structure prompts for prefix cache on mixture fan-out, aggregate per-brain economics into one receipt, and render every saving in the UI — not a spreadsheet.
