+Or connect your repository to Vercel for automatic deployments:
+
+1. Push your code to GitHub
+2. Connect your repository to [Vercel](https://vercel.com)
+3. Configure your environment variables in the Vercel dashboard
+4. Deploy automatically on every push

 > [!NOTE]
-> NuxtHub will automatically spawn a D1 database and apply the database migrations when deploying your project.
+> Make sure to configure your PostgreSQL database connection and run migrations in your production environment.
+
+The application is configured to use [Vercel AI Gateway](https://vercel.com/docs/ai-gateway) which provides:
+
+- **Unified API**: Access hundreds of AI models through a single endpoint
+- **High Reliability**: Automatic retries and fallbacks between providers
+- **Spend Monitoring**: Track usage and set budgets across all providers
+- **Load Balancing**: Distribute requests for optimal performance
+
+Simply configure your `AI_GATEWAY_API_KEY` in your Vercel environment variables for production use.
+
+## AI Gateway Setup
+
+1. Create a Vercel account at [vercel.com](https://vercel.com)
+2. Navigate to your [AI Gateway settings](https://vercel.com/dashboard/ai-gateway)
+3. Generate an API key for your project
+4. Add the key to your environment variables as `AI_GATEWAY_API_KEY`
 
-Optionally, you can create a [Cloudflare AI Gateway](https://developers.cloudflare.com/ai-gateway/) to have usage analytics and the ability to cache response to reduce costs. Once created, you can add the `NUXT_CLOUDFLARE_GATEWAY_ID` environment variable with the named of your gateway.
+The AI Gateway automatically handles authentication with all supported AI providers including OpenAI, Anthropic, Google, xAI, and many others.
