# OpenAI introduces Structured Outputs in the API

> OpenAI introduced Structured Outputs, allowing developers to supply JSON Schema constraints for model responses and function-call arguments. The announcement described support in the Chat Completions API and positioned strict schema adherence as a way to reduce parsing failures, while application validation and business rules remain necessary.
