A Practical Guide to OpenAI's New Decisions API

OpenAI's new Decisions API provides a dedicated endpoint for fast, structured decision-making tasks like classification, routing, or scoring. It is designed to be a faster and more efficient alternative to using general-purpose LLMs for these specific jobs, returning typed answers with probabilities. The API, which is based on the gpt-6-luna model, can process both text and images. The guide provides practical Python code examples for use cases such as routing support requests and checking documents for missing information, comparing its functionality to a rival product called JEV.
