+              <p>
+                Pool the compute power of multiple Apple Silicon devices into a single, unified LLM inference cluster using <strong>Exo</strong>. Run large models like <code>Llama 3.1 405B</code> that don't fit on a single machine — split across your MacBook, Mac Studio, and Mac Mini over Thunderbolt or network.
+              </p>
+              <p>
+                <strong>Automatic Device Discovery:</strong> Exo detects nearby devices automatically and distributes model layers using pipeline or tensor parallelism — no manual configuration needed.
+              </p>
+              <p>
+                <strong>OpenAI-Compatible API:</strong> DevoxxGenie connects to your Exo cluster just like any other local provider. Run powerful models entirely on your own hardware with zero cloud costs and full data privacy.
