+### Cloudflare AI Gateway
+
+Cloudflare AI Gateway lets you access models from OpenAI, Anthropic, Workers AI, and more through a unified endpoint. With [Unified Billing](https://developers.cloudflare.com/ai-gateway/features/unified-billing/) you don't need separate API keys for each provider.
+
+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 ID as environment variables.
+
+   ```bash title="~/.bash_profile"
+   export CLOUDFLARE_ACCOUNT_ID=your-32-character-account-id
+   export CLOUDFLARE_GATEWAY_ID=your-gateway-id
+   ```
+
+3. Run the `/connect` command and search for **Cloudflare AI Gateway**.
+
+   ```txt
+   /connect
+   ```
+
+4. Enter your Cloudflare API token.
+
+   ```txt
+   ┌ API key
+   │
+   │
+   └ enter
+   ```
+
+   Or set it as an environment variable.
+
+   ```bash title="~/.bash_profile"
+   export CLOUDFLARE_API_TOKEN=your-api-token
+   ```
+
+5. Run the `/models` command to select a model.
+
+   ```txt
+   /models
+   ```
+
+   You can also add models through your opencode config.
+
+   ```json title="opencode.json"
+   {
+     "$schema": "https://opencode.ai/config.json",
+     "provider": {
+       "cloudflare-ai-gateway": {
+         "models": {
+           "openai/gpt-4o": {},
+           "anthropic/claude-sonnet-4": {}
+         }
+       }
+     }
+   }
+   ```
