Failure stays contained.
One degraded provider should never take down your product. ModelLane isolates failures to the narrowest possible scope and routes around them automatically.
Failures are contained at the narrowest scope.
ModelLane separates resilience into three layers that act independently, so a problem in one place never becomes a problem everywhere.
Provider circuit breaker
When a provider becomes unhealthy, ModelLane opens a circuit and stops sending it traffic until it recovers.
Connection cooldown
A bad credential or exhausted key cools down only that connection. Other keys for the same provider keep working.
Model lockout
A failed or rate-limited model locks out at the provider-and-model scope, leaving the rest of the model family available.
Fallback, retries, and recovery.
Health signals feed routing continuously. Requests shift away from degraded routes and canary back in as providers recover — without code changes and without an on-call page.
