Structured Response

This function allows you to request GPT to answer in a specific format defined with zod

const response = await useGPT('How high is Mt. Everest?')
.toStructured(
    z.object({
        meters: z.number()
    })
)

// Output:
{ meters: 8849 }

`.toStructured(zodType)`

Sends the message but requests GPT to return the provided type. Use ZOD to define the return type.

Here is some information I stumbled upon while developing this:

OpenAI's API is very selective about zod's types. It really only supports basic structures but nothing like e.g. z.array(...).length() or .optional().
For nullable types there is a workaround with union: z.union([z.<your-type>(), z.null()])
