FastRouter: AI Model Routing and LLM Gateway

FastRouter: AI Model Routing and LLM Gateway It is an AI infrastructure platform that helps businesses run AI applications across 200+ AI models through one OpenAI-compatible API. It automatically routes requests to suitable models and providers while helping teams control costs, improve reliability, monitor usage, and manage AI applications. FastRouter also provides features such as automatic failover, caching, guardrails, evaluations, and access control. FastRouter acts as a gateway between an AI application and different AI models or providers. Instead of creating separate integrations for every model, developers can use one API and switch between models without changing their application code. Its automatic routing can consider factors such as model quality, cost, latency, and provider performance. If a model or provider fails, FastRouter can automatically retry or use another available option.

5 Benefits of Using of FastRouter

1. Saves AI Costs – Routing and caching features can help reduce unnecessary model spending.
2. Improves Reliability – Automatic retries and fallbacks help keep applications running.
3. Simplifies Development – One API can provide access to many AI models.
4. Better Monitoring – Teams can track costs, latency, errors, and usage.
5. More Flexibility – Developers can change models and providers without major application changes.

Features of FastRouter

• AI Model Routing: FastRouter can automatically select suitable models and providers for different requests.
• Automatic Failover: If a model or provider becomes unavailable, FastRouter can retry the request or route it to another option.
• 200+ AI Models: Developers can access more than 200 models through a single OpenAI-compatible gateway.
• Cost Optimization: Features such as provider routing, response caching, prompt caching, prompt compression, and Flex pricing can help reduce AI costs.
