 Instead of a Pydantic model you can pass a string that represents a [JSON Schema](https://json-schema.org/) specification to `generate.json`:

 ## From a function's signature
 
 Outlines can infer the structure of the output from the signature of a function. The result is a dictionary, and can be passed directly to the function using the usual dictionary expansion syntax `**`:
