# ATLAS > ATLAS is ilionx's AI gateway and monitoring platform. Teams call one OpenAI- or Anthropic-compatible gateway, and ATLAS routes each request to the right model provider with budgets and an audit trail. ## Overview - [ATLAS](https://docs.atlas.ilionx.dev/index.md): ATLAS is ilionx's AI gateway and monitoring platform. Your teams call one gateway through an OpenAI-compatible or Anthropic-compatible address. ATLAS routes… ## Getting started - [Getting started](https://docs.atlas.ilionx.dev/getting-started.md): Pick the path that matches your part: call models as a user, or set up an organisation as an Admin. - [Quickstart](https://docs.atlas.ilionx.dev/getting-started/quickstart.md): In about five minutes, you'll sign in, create an API key and make your first model call through the ATLAS gateway. - [Set up your first organisation](https://docs.atlas.ilionx.dev/getting-started/first-organisation.md): Go from an empty organisation to a first model request made with a project API key, and learn where each building block lives. ## Concepts - [Concepts](https://docs.atlas.ilionx.dev/concepts.md): Understand how ATLAS works before you follow a guide.
