openai-structured-output (OpenAI Structured Output Example)

This example demonstrates how to define JSON schemas for OpenAI's Structured Output feature in two different ways:

Inline schema definition - defined directly in the config file
External schema file - stored in a separate JSON or YAML file and referenced with file://

Usage

You can run this example with:

bash

npx promptfoo@latest init --example openai-structured-output
cd openai-structured-output

This example requires:

This example includes several files that demonstrate different approaches:

File	Description
`promptfooconfig.chat.yaml`	Chat API config using both inline and external schemas
`promptfooconfig.responses.yaml`	Responses API config using both inline and external schemas
`schema.responses.yaml`	External schema file for Responses API
`schema.chat.json`	External schema file for Chat API

bash

cd openai-structured-output
promptfoo eval -c promptfooconfig.chat.yaml
promptfoo eval -c promptfooconfig.responses.yaml
