The article “Introducing Structured Outputs” on the OpenAI Developer Forum announces the launch of Structured Outputs 2 in the API. This feature allows model outputs to adhere reliably to developer-provided JSON Schemas, addressing a long-standing request from users.

Key features include:

  1. Function Calling: Developers can set strict: true in function definitions to ensure that model outputs match the exact schema specified.
  2. JSON Schema as Response Format: Developers can supply a json_schema under the response_format option, with the ability to enforce strict adherence to the schema.

Structured Outputs are supported across all models that allow function calling and introduce new cost-saving efficiencies with the latest model, gpt-4o-2024-08-06. This model offers reduced pricing compared to previous versions.

The announcement encourages developers to explore these new capabilities in their projects.
