Neurometric Task Router is an API that intelligently routes AI tasks to the optimal model based on published benchmarks and user-defined quality requirements, rather than guessing from price tags or leaderboards. Users keep their OpenAI SDK, change the base URL to taskrouter, and set quality targets while the system automatically selects and maintains fallback chains of qualified models. Pricing is free for 1,000 routing decisions monthly, then $0.15 per 1,000 decisions, plus inference costs from providers with no markup.
