How to use this hub

Use this OpenAI buyer hub to decide whether OpenAI direct API, OpenRouter, Azure, GitHub, or an app-platform route should be your first test path across 56 cataloged OpenAI model entries.

Choose OpenAI direct API when official model IDs, native API behavior, account-level billing, and first-party feature rollout matter more than router flexibility.

Choose OpenRouter when you want fast price comparison, fallback options, and one API surface for testing OpenAI models against other providers before committing.

Choose Azure or GitHub routes when procurement, enterprise controls, cloud locality, or developer-seat workflow is more important than the lowest visible token price.
