 Generate a typed, structured object for a given prompt and [Zod](https://zod.dev/) schema using a language model.
 
 You can use `generateObject` to force the language model to return structured data, e.g. for information extraction,
 synthetic data generation, or classification tasks.
 
 ```ts
-import { experimental_generateObject } from 'ai';
