OpenAI's structured output feature aims to ensure that the outputs generated by the model strictly adhere to the JSON format provided by developers, enhancing output reliability. This feature first appeared at last year's Developer Day, improving the reliability of the model's ability to generate valid JSON outputs through the JSON format, but it did not ensure that the model responses conformed to a specific pattern. The new feature addresses this issue by constraining the model to match the patterns provided by developers, making it especially suitable for applications that convert unstructured input into structured data. Complex JSON

OpenAI has added structured output capabilities in its API, ensuring that generated outputs fully conform to a predefined JSON structure, significantly enhancing the reliability of the API and the accuracy of applications. This feature not only defines the structure of the JSON but also ensures the precision of the output. Additionally, the pricing has been adjusted, with input costs reduced by half and output costs decreased by one-third. The introduction of structured output addresses the limitations of the JSON mode in ensuring that outputs conform to specific structures, significantly improving the model's performance in structured output.
