      \x3CChatComponent />
    \x3C/AINativeProvider>
  );
}

function ChatComponent() {

    model: 'claude-3-5-sonnet-20241022',
    systemPrompt: 'You are a helpful assistant.',
  });

  const handleSend = () => sendMessage('Hello!');

  return (
    \x3Cdiv>
      {messages.map((msg, i) => (
        \x3Cdiv key={i}>\x3Cb>{msg.role}:\x3C/b> {msg.content}\x3C/div>
      ))}
      \x3Cbutton onClick={handleSend} disabled={isLoading}>
