+### Cloudflare AI Gateway
+
+Cloudflare AI Gateway lets you proxy requests to AI providers through Cloudflare's infrastructure with caching, rate limiting, and analytics.
+
+1. Head over to the [Cloudflare dashboard](https://dash.cloudflare.com/), navigate to **AI** > **AI Gateway**, and create a new gateway.
+
+2. Set your Account ID and Gateway name as environment variables:
+
+   ```bash
+   CLOUDFLARE_ACCOUNT_ID=your-account-id CLOUDFLARE_GATEWAY_NAME=your-gateway-name opencode
+   ```
+
+   Or add them to your bash profile:
+
+   ```bash title="~/.bash_profile"
+   export CLOUDFLARE_ACCOUNT_ID=your-account-id
+   export CLOUDFLARE_GATEWAY_NAME=your-gateway-name
+   ```
+
+3. If your gateway has authentication enabled, also set your API token:
+
+   ```bash title="~/.bash_profile"
+   export CLOUDFLARE_API_TOKEN=your-api-token
+   ```
+
+4. Many Cloudflare AI Gateway models are preloaded by default, run the `/models` command to select the one you want.
+
+   ```txt
+   /models
+   ```
+
+   You can also add additional models through your opencode config.
+
+   ```json title="opencode.json" {6}
+   {
+     "$schema": "https://opencode.ai/config.json",
+     "provider": {
+       "cloudflare-ai-gateway": {
+         "models": {
+           "some-other-model": {}
+         }
+       }
+     }
+   }
+   ```
