 The Ollama API does not call the function directly; instead, the model generates JSON that you can use to call the function in your code and return the result back to the model to complete the conversation.
 Spring AI provides flexible and user-friendly ways to register and call custom functions.
-In general, the custom functions need to provide a function `name`,  `description`, and the function call `signature` (as JSON schema) to let the model know what arguments the function expects.

 The `description` helps the model to understand when to call the function.

 Your function can in turn invoke other 3rd party services to provide the results.
 
 Spring AI makes this as easy as defining a `@Bean` definition that returns a `java.util.Function` and supplying the bean name as an option when invoking the `ChatModel`.
