Instructor is a Python library that bridges OpenAI responses with structured data validation using Pydantic models. It lets developers specify expected output schemas and ensures that the responses from OpenAI APIs are automatically parsed and validated against those models. This makes integrating LLMs into structured workflows safer and more predictable, especially in production applications.

Features

  • Validates LLM output using Pydantic models
  • Supports OpenAI function calling and raw responses
  • Reduces hallucinations and malformed data
  • Easy integration with structured apps and APIs
  • Provides decorators for minimal boilerplate
  • Compatible with OpenAI’s ChatCompletion interface
