Streaming Semantic Events

You're building a weather assistant that provides real-time forecasts. The OpenAI client has been initialized and configured to work with the Responses API. You'll stream semantic events to track when the response starts, when text blocks finish, and when the full response is complete. This creates a more engaging user experience by showing progress as the model generates the forecast.
