typesafe/jev-router: cache-aware model router by Jev and @typesafeai
A router that tunes model choice and reasoning effort per request shifts the cost-quality decision from manual selection to automated policy, which can cut token bills without per-app configuration. Developers building multi-model applications can adopt it to benchmark cache-aware routing against static model pickers. Teams serving high-volume chat or agent traffic stand to gain the most.
