OpenAI Introduces Structured Outputs - A Breakthrough for Developers

OpenAI has launched "Structured Outputs," a new API feature designed to solve the persistent challenge of generating reliable structured data from large language models (LLMs). This ensures that the output matches the developer's specified JSON Schemas.

Generating structured data from unstructured input is vital for many AI applications. Developers use the OpenAI API to build advanced assistants capable of data retrieval, answering complex queries, extracting structured data for seamless data entry, and enabling multi-step workflows.

Previously, developers had to use workarounds like open-source tools, complex prompting, and repeated requests to manage the limitations of LLMs in producing structured outputs. These methods, while effective, added complexity and reduced efficiency.

OpenAI’s Structured Outputs eliminate these issues by ensuring models adhere to developer-supplied schemas and better understand complex data structures. Internal tests using intricate JSON schemas show that the latest model, gpt-4o-2024-08-06, achieved a perfect 100% adherence rate, a significant improvement over the earlier gpt-4-0613 model, which scored less than 40%.

Key Implementations

• Function Calling

By setting strict: true within a function definition, developers can define the exact structure of data returned by functions. This feature is compatible with models like gpt-4-0613, gpt-3.5-turbo-0613, and newer versions.

• Response Format Parameter

Developers can provide a JSON Schema via the new json_schema option within the response_format parameter. This is useful for models responding directly to users in a structured format without invoking tools. This feature is supported by the latest GPT-4o models.

OpenAI has prioritized safety in Structured Outputs, aligning it with existing safety policies. The model can refuse unsafe requests, indicated by a new refusal string value in API responses, ensuring predictable behavior and simplified error handling.

Native support for Structured Outputs is integrated into OpenAI’s Python and Node SDKs, making it easier for developers to use. The SDKs automatically convert Pydantic or Zod objects to JSON Schema and handle the deserialization of JSON responses into typed data structures.
