RealtimeResource class

Resource for Realtime API operations.

The Realtime API enables real-time audio conversations with the model using WebSockets.

Access this resource through OpenAIClient.realtime.

Example

// Connect to a realtime session
final session = await client.realtime.connect(
  model: 'gpt-realtime-2',
);

// Listen for events
session.events.listen((event) {
  if (event is ResponseTextDeltaEvent) {
    stdout.write(event.delta);
  }
});

// Send a user text message and let the model respond
session.sendUserMessage('Say hello');

// Or stream audio bytes (24 kHz PCM16 mono for realtime sessions)
session.appendAudioBytes(audioBytes);

// Close when done
await session.close();
