)

stream = client.responses.create(
    model="not-needed",
    input="Search for Python documentation",
    stream=True
)

for event in stream:
    if event.type == "response.output_text.delta":
        # Real-time thoughts and actions (contains spaces)
        if ' ' in event.delta:
            print(event.delta, end="", flush=True)
    elif event.type == "response.completed":
        # Final result
        print("\nTask completed:", event.response.output[0].content[0].text)

​
2. Screenshots

for event in stream:
    if event.type == "response.output_text.delta":
        # Screenshot data (no spaces)
        if ' ' not in event.delta:
            print("Screenshot data received:", event.delta)

3. Task Progress

    match event.type:
        case "response.created":
            print("Task created")
        case "response.in_progress":
            print("Task started")
        case "response.output_text.delta":
            # Process updates
            pass
        case "response.output_text.done":
            print("Intermediate result completed")
        case "response.completed":
