--- title: "Output Format" description: "The default is text. But you can define a structured output format to make post-processing easier." icon: "code" --- ## Custom output format With [this example](https://github.com/browser-use/browser-use/blob/main/examples/features/custom_output.py) you can define what output format the agent should return to you. ```python from pydantic import BaseModel # Define the output format as a Pydantic model class Post(BaseModel): post_title: str post_url: str num_comments: int hours_since_post: int class Posts(BaseModel): posts: List[Post] controller = Controller(output_model=Posts) async def main(): task = 'Go to hackernews show hn and give me the first 5 posts' model = ChatOpenAI(model='gpt-4o') agent = Agent(task=task, llm=model, controller=controller) history = await agent.run() result = history.final_result() if result: parsed: Posts = Posts.model_validate_json(result) for post in parsed.posts: print('\n--------------------------------') print(f'Title: {post.post_title}') print(f'URL: {post.post_url}') print(f'Comments: {post.num_comments}') print(f'Hours since post: {post.hours_since_post}') else: print('No result') if __name__ == '__main__': asyncio.run(main()) ```
