# Stream Object

Object generation can sometimes take a long time to complete,
especially when you're generating a large schema.

In Generative UI use cases, it is useful to stream the object to the client in real-time
to render UIs as the object is being generated.
You can use the [`streamObject`](/docs/reference/ai-sdk-core/stream-object) function to generate partial object streams.

```ts file='index.ts'
import { streamObject } from 'ai';
import { z } from 'zod';

const { partialObjectStream } = streamObject({
  model: 'openai/gpt-4.1',
  schema: z.object({
    recipe: z.object({
      name: z.string(),
      ingredients: z.array(z.string()),
      steps: z.array(z.string()),
    }),
  }),
  prompt: 'Generate a lasagna recipe.',
});

for await (const partialObject of partialObjectStream) {
  console.clear();
  console.log(partialObject);
}
```
