 **How it works:**
-1. First request: System prompt, tools, and the user message "Hi, my name is Bob" are sent to the API and cached
-2. Second request: The cached content (system prompt, tools, and first message) is retrieved from cache. Only the new message "What's my name?" needs to be processed, plus the model's response from the first request
