### Step 1. Open Cursor Settings

In Cursor, open **Settings** and go to the **Models** tab. Scroll down to the **API Keys** section.

### Step 2. Add Your Sunrise API Key

Paste your Sunrise API Key into the **OpenAI API Key** field, then set **Override OpenAI Base URL** to:

```
https://maas.ai.sunrise.ch/v1
```

Make sure both toggles are enabled (green).

### Step 3. Add Your Model

At the bottom of the model list click on "Add a model". Get the exact model name from the Sunrise Active Models list. For example:

```
inference-apertus-70b
inference-gpt-oss-120b
inference-glm5
```

> **Recommended:** Use `inference-glm5` for the best Cursor experience. GLM 5 is optimized for agentic engineering and long-horizon coding, and is the only model that fully supports **Agent**, **Chat**, and **Plan** modes in Cursor.

Paste the name into Cursor and enable the toggle for the newly added model.

### Step 4. Test It

Open **Ask** mode with `Cmd+L` / `Ctrl+L` and select your model.

## Troubleshooting

| Issue | Solution |
|-------|----------|
| Model not responding | Check base URL ends with `/v1` and key has model access |
| Auth errors | Regenerate key; ensure it starts with `sk-` |
| Agent mode not working | Use `inference-glm5`; other models only support Ask and Plan modes |
