Introducing Structured Outputs
Key point
OpenAI has launched a Structured Outputs feature that ensures model outputs comply 100% with a specified JSON schema.
Details
Existing LLM outputs had unstable formatting, forcing developers to spend significant costs handling JSON parsing errors. OpenAI has introduced Structured Outputs, a feature that ensures the model complies 100% with a JSON schema defined by the user.
This feature uses a method that constrains the model, as it generates tokens, from producing tokens that deviate from the schema. This allows developers to obtain reliable structured data without complex prompt engineering.
Key features:
- 100% schema compliance: Perfectly follows the specified JSON format
- Development convenience: Reduces additional logic needed for handling parsing errors
- API support: Immediately applicable via the
json_schemaresponse format
