What is AI Gateway?
A proxy layer between your application and LLM providers that handles routing, caching, failover, and observability.
An AI gateway sits between your application and AI model providers like OpenAI and Anthropic. It intercepts every API call, applies optimizations like caching and intelligent routing, and forwards requests to the best available provider. Unlike traditional API gateways, AI gateways understand token-based pricing, prompt semantics, and LLM-specific rate limits.
Examples
- → Routing requests to GPT-4 for complex tasks and GPT-4o-mini for simple ones
- → Automatically failing over to Claude when OpenAI is down
- → Caching similar prompts to reduce costs
