Describe the task, request size, and constraints that should activate a route.
Right request.
Right model.
Build an ordered policy, simulate every decision locally, enforce request budgets, recover through explicit fallbacks, and export the complete production configuration.
Choose the first appropriate model using ordered, inspectable rules.
Block estimates above the policy cost ceiling before live execution.
Attempt explicit fallbacks only when the selected route fails.
Take the complete policy into an application as JSON or TypeScript.
Define the operating limits.
Rules run from top to bottom. The first complete match selects the primary model; the fallback chain is used only when execution fails.
3 decision gates
Ordered recovery routes after a provider or model failure.
See the decision before spending a token.
Simulation is deterministic and local. It shows every rule checked, the reason for selection, the fallback chain, and an estimate based on the configured token ceiling.

Nemotron 3.5 Lightning
Run the policy, including fallbacks.
The router calls only the selected primary. A fallback is attempted only when the previous route returns an execution failure.
Take the policy with you.
Export the entire ordered policy as portable JSON or a typed TypeScript configuration.
