To use an AI Agent, you’ll need to register a large language model (LLM). For self-hosted
applications, you must provide your own model. If you'd prefer Sidecar CX to handle language model
management, consider using the hosted Cloud application.

## Supported Large Language Models

- OpenAI

## How to Add Your Large Language Model in the Self-Hosted Application

2. Navigate to [Account Settings](https://app.sidecarcx.com/my-account) and select
   `Language Models`.
3. Paste your OpenAI API key into the `OpenAI API Key` field and click `Save`. If successful, a
   `Language model saved` toast message will appear.
