# AI Gateway

AI Gateway nodes let you call AI providers from the Flow Editor using a consistent input/output format. These nodes work with [AI Routes](/documentation-and-resources/components-and-data/ai-routes.md) and [AI Connections](/documentation-and-resources/components-and-data/connections/types-of-connections/ai-connections.md) to manage providers, models, and failover.

## Where to Find These Nodes

In the Flow Editor, within the left palette under **AI Gateway** category.

## Node Reference

* [AI Generate](/documentation-and-resources/components-and-data/flows/node-reference/ai-gateway/ai-generate.md) - Send requests to AI Gateway and receive structured responses.
