    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "fal-ai/flux/srpo",
    arguments={
        "prompt": "Mountain guide, sturdy build, wilderness wisdom, alert gaze, technical outdoor gear with rope coils, snow-capped peaks background, crisp mountain lighting, leading pose, wind-swept hair with full beard, weather-worn face with quiet confidence, alpine expert presence"
    },
