Imagen 4 常見問題
What is the maximum output resolution?
Up to 2K resolution natively. The ultra variant pushes quality further for brand and marketing use.
How do the fast, standard, and ultra variants differ?
Fast generates in ~2.7 seconds for drafts. Standard balances quality and cost. Ultra delivers maximum photorealism for final production assets.
How accurate is text rendering in Imagen 4?
Imagen 4 has strong typography support — it reliably renders short text like brand names, labels, and headlines within images.
What is the pro remix image variant for?
It takes source images as style or content seeds and generates a new image guided by both the sources and your text prompt.
Does Imagen 4 support transparent backgrounds?
Not natively. For transparent backgrounds, generate the image and then use a background removal tool like Recraft.
我應該先用邊個版本？
先選最平而且符合你質素要求的版本。大多數團隊會先用快速版本，之後再升級到 pro 用於正式生產。
