[Kilo Code](https://kilo.ai) is an open-source AI coding agent extension for VS Code that works with any OpenAI-compatible provider (BYOK mode). Point it at CrossModel and you can use the whole catalog inside VS Code.

## Quickstart

### 1. Install Kilo Code

Search for **Kilo Code** in the VS Code Extensions panel, or install it from the [Visual Studio Marketplace](https://marketplace.visualstudio.com/items?itemName=kilocode.kilo-code).

### 2. Create an API key

Sign in to the [Console](/console/api-keys) and create a key that starts with `cm-` on the **API Keys** page. The key is shown only once, so copy it somewhere safe.

### 3. Point Kilo Code at CrossModel

Click the Kilo Code icon in the VS Code sidebar, open the settings panel, and fill in:

| Field | Value |
|-------|-------|
| **API Provider** | `OpenAI Compatible` |
| **Base URL** | `https://api.crossmodel.ai/v1` |
| **API Key** | your `cm-` key |
| **Model** | Kilo Code fetches the available models once the URL is set |

Once you enter the base URL, Kilo Code pulls the model list from that endpoint automatically — just pick the one you want.

### 4. Start using it

Send a message in the Kilo Code chat panel and your requests will route through CrossModel to the model you picked.

## Choosing models

Model IDs follow the `vendor/short_name` format, e.g. `openai/gpt-5.5`, `anthropic/claude-sonnet-4.6`, or `deepseek/deepseek-v4-flash`. See the full list in the [model catalog](/models).

## Troubleshooting

| Symptom | What to check |
|---------|---------------|
| Empty model list | Make sure the base URL ends with `/v1` and the key starts with `cm-` and is valid. |
| Auth failure | Re-check the API key. It's shown only once, so create a new one in the Console if you've lost it. |
| "Model not found" | Check the model ID format; casing must match exactly. |
| Insufficient balance | Top up in the [Console](/console/billing). |
