-Earlier functions like `generateText` and `streamText` gave us the ability to generate unstructured text. However, if you want to generate structured data like JSON, you can provide a schema that describes the structure of your desired object to the `generateObject` function.
-
-The function requires you to provide a schema using [zod](https://zod.dev), a library for defining schemas for JavaScript objects. By using zod, you can also use it to validate the generated object and ensure that it conforms to the specified structure.

-## Client
-
-Let's create a simple React component that will make a POST request to the `/api/completion` endpoint when a button is clicked. The endpoint will return the generated object based on the input prompt and we'll display it.
-
-```tsx filename='pages/index.tsx'
-import { useState } from 'react';
-
-export default function Page() {
-  const [generation, setGeneration] = useState();
-  const [isLoading, setIsLoading] = useState(false);
-
-  return (
-    <div>
-      <div
-        onClick={async () => {
-          setIsLoading(true);
-
-          await fetch('/api/completion', {
-            method: 'POST',
-            body: JSON.stringify({
-              prompt: 'Messages during finals week.',
-            }),
-          }).then(response => {
-            response.json().then(json => {
-              setGeneration(json.object);
-              setIsLoading(false);
-            });
-          });
-        }}
-      >
-        Generate
-      </div>
-
-      {isLoading ? 'Loading...' : <pre>{JSON.stringify(generation)}</pre>}
-    </div>
-  );
-}
-```
-
-## Server
-
-Let's create a route handler for `/api/completion` that will generate an object based on the input prompt. The route will call the `generateObject` function from the `ai` module, which will then generate an object based on the input prompt and return it.
-
-```typescript filename='app/api/completion/route.ts'
-import { generateObject } from 'ai';
-import { openai } from '@ai-sdk/openai';
-import { z } from 'zod';
-
-export async function POST(req: Request) {
-  const { prompt }: { prompt: string } = await req.json();
-
-  const result = await generateObject({
-    model: openai('gpt-4'),
-    system: 'You generate three notifications for a messages app.',
-    prompt,
-    schema: z.object({
-      notifications: z.array(
-        z.object({
-          name: z.string().describe('Name of a fictional person.'),
-          message: z.string().describe('Do not use emojis or links.'),
-          minutesAgo: z.number(),
-        }),
-      ),
-    }),
-  });
-
-  return result.toJsonResponse();
-}
-```
