my ai cookbook models openai 04 structured output at main

When working with the OpenAI API directly, you have two main options for obtaining structured output responses from GPT models: JSON mode and Function calling. While both are powerful tools, they also have their limitations. Understanding when to use each can enhance your workflow and give you more control over the output. After learning about these two methods, we'll dive into Instructor to gain even greater control over the output from OpenAI's models. Instructor was covered in this great "Pydantic is all you need" talk by Jason Liu. Using JSON output in your LLM applications provides more control and validation over the generated responses.

It ensures that the output is always a valid JSON string, making it easier to parse and process the data in your application. In JSON mode, the model generates outputs exclusively formatted as valid JSON strings. However, you need to explicitly specify the desired JSON structure within the system prompt to guide the model towards the expected format. It's important to note that OpenAI does not guarantee that the output text will have your specified JSON format. It only ensures that the output will be a valid string that can be parsed to JSON. Important: When using JSON mode, you must also instruct the model to produce JSON yourself via a system or user message.

Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request. Also note that the message content may be partially cut off if finish_reason="length", which indicates the generation exceeded max_tokens or the conversation exceeded the max context length. Structured Outputs is a new capability in the Chat Completions API and Assistants API that guarantees the model will always generate responses that adhere to your supplied JSON Schema. In this cookbook, we will illustrate this capability with a few examples. Structured Outputs can be enabled by setting the parameter strict: true in an API call with either a defined response format or function definitions. Previously, the response_format parameter was only available to specify that the model should return a valid JSON.

In addition to this, we are introducing a new way of specifying which JSON schema to follow. Function calling remains similar, but with the new parameter strict: true, you can now ensure that the schema provided for the functions is strictly followed. In the realm of AI-driven applications, ensuring consistent and predictable outputs is paramount. OpenAI’s introduction of Structured Outputs addresses this need by allowing developers to define the exact format of the model’s responses, ensuring they adhere to specified schemas. Structured Outputs enable developers to constrain the model’s responses to a predefined structure, typically defined using JSON Schema. This ensures that the outputs are not only valid JSON but also match the expected format, reducing the need for post-processing and error handling.

OpenAI’s new Structured Outputs feature is designed to ensure that model-generated outputs exactly match JSON schemas that you provide. This feature is particularly beneficial for developers who need consistent and structured data formats, whether for API integration, data processing or application development. This document details techniques for obtaining typed, structured data from Large Language Models (LLMs) using Pydantic models with the OpenAI SDK.

Structured output serves as a foundational pattern in the AI Cookbook for transforming natural language into validated, programmatically accessible data structures. For information about integrating structured output with knowledge base retrieval, see Knowledge Retrieval Patterns. The structured output pattern leverages Pydantic models to define data schemas and instructs LLMs to conform to these schemas using OpenAI's parse method.

Some benefits of Structured Outputs include: In addition to supporting JSON Schema in the REST API, the OpenAI SDKs for Python and JavaScript also make it easy to define object schemas using Pydantic and Zod respectively. Below, you can see how to extract information from unstructured text that conforms to a schema defined in code. Structured Outputs is available in our latest large language models, starting with GPT-4o. Older models like gpt-4-turbo and earlier may use JSON mode instead.
