# Welcome to the Corti API

> The AI platform for industry developers

The Corti API brings AI into any application: speech to text, text generation, agentic workflows, medical coding, and an embeddable assistant. It's a single platform built for industry use, so you can add production-grade AI to your product without building the models, infrastructure, or compliance yourself.

## Corti Models

Corti Models gives you access to cutting-edge LLMs, embedding models, and more through an OpenAI API-compatible platform. EU projects can deploy on a sovereign EU cluster with no external dependencies, with GDPR compliance built in by default. US projects reach Corti Models through Azure-hosted OpenAI models instead, under the same model IDs. See [Regions](/models/regions) for the full breakdown. [**Get started with Corti Models**](/models/welcome).
