+description: "Configure app.nz with Continue to access a hosted OpenAI-compatible LLM gateway with automatic model routing across multiple providers, including API setup instructions"
+---
+
+<Info>
+  app.nz is a hosted, OpenAI-compatible LLM gateway with an automatic router that selects the best model for each request across multiple providers.
+</Info>
+
+<Tip>
+  Get an API key from the [app.nz dashboard](https://app.nz/) and read the [docs](https://app.nz/docs).
+</Tip>
+
+## Configuration
+
+app.nz exposes an OpenAI-compatible API at `https://app.nz/v1`, so it is configured with the `openai` provider and a custom `apiBase`. Use the `app/auto` model to let the router pick the best model automatically.

+      }
+    ]
+  }
+  ```
+  </Tab>
+</Tabs>
+
+## Available Models
+
+`app/auto` routes each request to the best available model. You can also target a routing variant tuned for a specific workload, or address any upstream model directly with `provider/model`.
+
+| Model | Best For |
+|-------|----------|
+| `app/auto` | General use, balanced routing (recommended) |
+| `app/auto-code` | Coding and editing tasks |
+| `app/auto-reasoning` | Complex reasoning and planning |
+| `app/auto-fast` | Low-latency responses |
+| `app/auto-cheap` | Maximum cost savings |
+| `app/auto-vision` | Image and multimodal input |
+
+To use a specific upstream model instead of the router, pass it as `provider/model` (for example `anthropic/claude-sonnet-4` or `openai/gpt-4o`).
+
+## Using Multiple Roles
