-Enable and customize your gateway cache to serve requests directly from Cloudflare's cache, instead of the original model provider, for faster requests and cost savings.
+AI Gateway can cache responses from your AI model providers, serving them directly from Cloudflare's cache for identical requests.
+
+## Benefits of Using Caching
+
+- **Reduced Latency:** Serve responses faster to your users by avoiding a round trip to the origin AI provider for repeated requests.
+- **Cost Savings:** Minimize the number of paid requests made to your AI provider, especially for frequently accessed or non-dynamic content.
+- **Increased Throughput:** Offload repetitive requests from your AI provider, allowing it to handle unique requests more efficiently.

+To address these needs, AI Gateway allows you to override default cache behaviors on a per-request basis using specific HTTP headers. This gives you the precision to optimize caching for individual API calls, ensuring the right balance of performance, cost-efficiency, and data accuracy.
+
+The following headers allow you to define this per-request cache behavior:
