How it works

"One integration.
Three guarantees."

◉

Smart Routing

Cost, latency, and capability-aware routing. Set explicit rules or let ModelOS decide — per request, in real time.

# routing rule if tokens < 500 → claude-haiku else → claude-sonnet fallback: gpt-4o on 5xx
◑

Credit Controls

Per-key spending caps, team budgets, overage policies. Hard limits or alerts. No surprise invoices.

30% on raw inference.
Itemized on every invoice.

Raw provider cost is always shown. Our margin is fixed and transparent — it covers routing, failover, and monitoring.
