# GitHub Copilot

> Use Kyma models with GitHub Copilot in VS Code.

GitHub Copilot supports custom OpenAI-compatible endpoints. You can route Copilot through Kyma to access Kyma's active open models.

## Configuration

In VS Code, open Settings (`Cmd+,`) and search for `github.copilot`:

1. Set **Copilot: Advanced** → **API URL** to:

```
https://kymaapi.com/v1
```

2. Set your Kyma API key in the authentication field.

Alternatively, set environment variables:

```bash theme={null}
export OPENAI_API_KEY="ky-your-api-key"
export OPENAI_BASE_URL="https://kymaapi.com/v1"
```

## Recommended Models

| Model               | Alias   | Best For                                                              |
| ------------------- | ------- | --------------------------------------------------------------------- |
| `qwen-3-32b`        | `fast`  | **Recommended** — fast code completion                                |
| `qwen-3.6-plus`     | `best`  | Highest quality                                                       |
| `qwen-3-coder`      | `code`  | Best alias for code-focused tasks                                     |
| `kimi-k2.6`         | `agent` | Best tool calling                                                     |
| `deepseek-v4-pro`   | —       | 1M context, top reasoning. Complex refactors and long-codebase tasks. |
| `deepseek-v4-flash` | —       | 1M context, value tier. Everyday completions where speed matters.     |

See all [model aliases](/guides/model-aliases) for shortcuts.

## Notes

* Kyma is OpenAI-compatible, so any Copilot setup that supports custom OpenAI endpoints will work.
* For inline completions, use a fast model like `qwen-3-32b` or alias `fast`.

## Prompt Caching

Prompt caching is automatic. Your system prompt and tool definitions are cached for 5 minutes, reducing costs by up to 90% on subsequent requests. No code changes needed. See [Prompt Caching](/guides/prompt-caching) for details.
