Using Instructor Elixir Library to Handle Sum Types with Ecto

The article by Samrat Man Singh discusses how to utilize the Instructor Elixir library to retrieve structured responses from large language models (LLMs) like GPT models. It focuses on handling sum types in Ecto schemas, which Ecto doesn’t natively support. The author provides detailed examples, including defining Ecto schemas for multiple choice and slider questions, creating custom Ecto types, and generating JSON schemas to handle these types effectively. The article highlights the challenges and solutions for making sum types work within the Elixir ecosystem using Ecto and the Instructor library.
