OpenAI has introduced Structured Outputs for its API, enabling models to reliably adhere to developer-provided JSON Schemas. This new feature enhances the accuracy of AI-generated structured data, a common use case for applications like data extraction and agentic workflows. The system achieves 100% reliability in evaluations with its latest GPT-4o model, significantly outperforming previous versions. Structured Outputs can be integrated via function calling with "strict: true" or through a new "json_schema" option in the "response_format" parameter for GPT-4o models. AI
RANK_REASON This is a product update to an existing API, not a new model release or a paradigm-shifting capability.
