Google Gemini 2.5 Flash efficient image generation model (Nano banana)
Use model parameter to select gemini-2.5-flash-image-preview model
Supports text-to-image generation
Async task management, query results by task ID

Important Change: For better performance and cost control, we no longer support passing base64 image data directly in image_urls. Please use the Upload 画像API first to upload images and get URLs, then call this endpoint.
