Essentially, it guarantees the output from the GPT will follow a defined structure (JSON object).\n- It uses Tailwind CSS to make it slightly nicer, but any\n\n**How it works**\n- Once active, go to the production URL and add what you'd like to build as the parameter \"query\"\n- Example: https:\/\/production_url.com?query=a%20signup%20form\n- OpenAI nodes will first output the UI as a JSON then convert it to HTML\n- Finally, the response is integrated in a HTML container and rendered to the user\n\n**Further thoughts**\n- Results are not yet amazing, it is hard to see the direct value of such an experiment\n- But it showcase the potential of the Structured Output. Being able to guarantee the output format is key to build robust AI applications."
