A production LLM routing gateway
A routing gateway that directs every model call by cost, quality, and provider health — and degrades gracefully when a provider does not.

Problem
Applications had grown dependent on multiple model providers with different cost, quality, and failure profiles — and no way to route a single request to the right model deterministically.

Engineering decisions
Cost-aware routing
Requests route to the model that meets the quality bar at the lowest cost, with budgets enforced per tenant.
Circuit-breaker-induced model selection
When a provider degrades, its circuit breaker opens and the router selects an alternate model — selection is driven by health, not fixed mappings.
Quality-aware routing
Routing accounts for the capability a request actually needs, matching hard tasks to stronger models and easy ones to fast, cheap ones.
Declarative routing
Routing policy is expressed as data — not code — so it can be changed, audited, and versioned without a deploy.
