```jsx CopilotRuntime Example
const copilotKit = new CopilotRuntime();
return copilotKit.response(req, new OpenAIAdapter());
```

You can easily set the model to use by passing it to the constructor.
```jsx
const copilotKit = new CopilotRuntime();
return copilotKit.response(
  req,
  new OpenAIAdapter({ model: "gpt-4o" }),
);
```
 
To use your custom OpenAI instance, pass the `openai` property.
```jsx
const openai = new OpenAI({
  organization: "your-organization-id",
  apiKey: "your-api-key"
});
 
const copilotKit = new CopilotRuntime();
return copilotKit.response(
  req,
  new OpenAIAdapter({ openai }),
);
```
