OpenAI introduces Structured Outputs in the API
OpenAI released Structured Outputs, which guarantees model responses match a developer-supplied JSON schema, and made the feature available across GPT-4o and its smaller models at no extra cost.
Why it matters
Reliable JSON-schema compliance is the foundation for production agent systems, tool calls, and database writes, and Structured Outputs removes the biggest source of brittleness in production LLM code.
