+## Overview
+
+This guide explains how to integrate LiteLLM with Fireworks AI. You can connect to Fireworks AI in three main ways:
+
+1. <b> Using Fireworks AI serverless models </b> – Easy connection to Fireworks-managed models.
+2. <b> Connecting to a model in your own Fireworks account </b> – Access models that are hosted within your Fireworks account.
+3. <b> Connecting via a direct-route deployment </b> – A more flexible, customizable connection to a specific Fireworks instance.
