Route every LLM call to the best model by cost and complexity
Optimize AI spend with Intelligent Routing
Why Rerout?
Smart infrastructure for production AI applications
Cost-aware routing
Automatically route simple requests to cheaper models. Save 30-50% on your LLM costs without sacrificing quality where it matters.
Complexity-based selection
Analyze request complexity in real-time. Route to capable models only when needed: simple queries get fast, cheap responses.
Resilience + fallback
When a provider goes down, your app keeps running. Automatic failover to backup models with configurable retry policies.
One line change
Switch your base URL. That's it.
const client = new OpenAI({
baseURL: 'https://api.openai.com/v1'
});const client = new OpenAI({
baseURL: 'https://api.rerout.com/v1'
});Your existing code works unchanged. Rerout handles routing, fallbacks, and cost optimization.
How it works
Simple architecture, powerful routing logic
Each request is analyzed for complexity, enriched with memory context, matched against your routing policies, and sent to the optimal model.
