Lever guide
What one lever does, its risk control, and how a policy enables it.
Lever 9
Host arbitrage
For an open-weight model, pick the cheapest healthy host.
PlannedLever 9
Risk control
Health, latency and region policy still apply.
This lever is not a silent model switch.
How a policy turns it on
Planned. Routing policies are designed to be per route. You would tag the route with X-Parezen-Route, then enable the lever on that route in the dashboard. Ignore is recorded. Nothing quality-affecting is enabled without a passed shadow test.
