What is Model Router?
Model Router is an OpenAI-compatible AI API gateway that forwards chat and embeddings requests to multiple model providers. Instead of hard-coding a specific model name, clients can specify a capability tier (economy, standard, premium, or auto) and an optimization preference (cheap, fast, balanced, quality, coding). The router selects an eligible model and adapts when providers are unavailable or when cheaper options appear, without requiring code changes. It includes a context-window guard to avoid routing to models that cannot handle the input size, and circuit breakers that reroute around outages. Responses include headers identifying the chosen provider and model, plus a request ID for tracing. Accounts use email-code login, prepaid credits with a deposit fee, and billing at provider market rates. Additional controls include blocking specific providers, auto-recharge, daily spend limits, streaming and tool call support, and exporting traces to any OTLP observability backend.
Problem this tool solves
Apps must integrate many LLM APIs and handle outages, pricing, and model changes.
How it solves the problem
OpenAI-compatible gateway routes requests across providers by tier/preference automatically.
Target Audience
Developers using multiple LLM providers via an OpenAI-style API.
