Cirrus runs a managed inference layer that routes each request to the cheapest model and hardware combination able to meet a declared quality bar.

Routing quality rather than raw speed is the differentiator. The interesting claim is that most production traffic is easy, and paying frontier prices for all of it is simply waste.
A serving layer that sends each request to the cheapest model meeting a declared quality threshold rather than defaulting to the largest available model.
