+### Cloudflare Workers AI
+
+Cloudflare Workers AI lets you run AI models on Cloudflare's global network directly via REST API, with no separate provider accounts needed for supported models.
+
+1. Head over to the [Cloudflare dashboard](https://dash.cloudflare.com/), navigate to **Workers AI**, and select **Use REST API** to get your Account ID and create an API token.
+
+2. Set your Account ID as an environment variable.
+
+   ```bash title="~/.bash_profile"
+   export CLOUDFLARE_ACCOUNT_ID=your-32-character-account-id
+   ```
+
+3. Run the `/connect` command and search for **Cloudflare Workers AI**.
+
+   ```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_KEY=your-api-token
+   ```
+
+5. Run the `/models` command to select a model.
+
+   ```txt
+   /models
+   ```
+
+---
+
 ### Cortecs
 
 1. Head over to the [Cortecs console](https://cortecs.ai/), create an account, and generate an API key.

+##### GitLab Duo Agent Platform (DAP) Workflow Models
+
+DAP workflow models provide an alternative execution path that routes tool calls
+through GitLab's Duo Workflow Service (DWS) instead of the standard agentic chat.
+When a `duo-workflow-*` model is selected, OpenCode will:
+
+1. Discover available models from your GitLab namespace
+2. Present a selection picker if multiple models are available
+3. Cache the selected model to disk for fast subsequent startups
+4. Route tool execution requests through OpenCode's permission-gated tool system
+
+Available DAP workflow models follow the `duo-workflow-*` naming convention and
+are dynamically discovered from your GitLab instance.
