圖生圖 核心技術亮點
專為高精準度、迅捷回應與創意自由度深度打造。
The photo leads
The reference carries identity and composition. The prompt carries the change.
One change at a time
Background, clothing, or style. Stacking many changes in one prompt makes the subject drift.
A cheaper edit on Nano Banana 2
That route is 4 credits, less than a Pro still and less than a 4K 2.5 generation.
Multi-reference on 2.5
Use up to three images when identity, style, and layout come from different sources.

If you have no photo
Use Text to Image first
Image to image is the edit path. You upload a reference and write the change in ordinary language: a new background, a different outfit, a tighter crop, or another medium. The subject should remain recognizable because the picture, not only the prompt, is the starting point.
Credit cost follows the route. Attaching a reference to Nano Banana 2 uses the edit route at 4 credits. Nano Banana Edit and Nano Banana 2 Lite stay at 6 credits. Nano Banana 2.5 accepts up to three references when one image should guide identity, another the style, and a third the layout.
如何使用 圖生圖
- 01
Upload a clear reference
Use a photo where the subject is large enough to see. JPEG, PNG, and WebP are accepted.
- 02
Say what stays
Name the face, product, or layout that must survive, then name the one change you want.
- 03
Add references only when they do a job
A second image can carry style or setting. Do not upload extras that contradict the first.
圖生圖 適合做什麼
Outfit and prop changes
Describe the new clothing or object while asking the face or product shape to stay.
Style transfer
Turn a photo into ink, clay, or an editorial still without redrawing the pose.
Campaign continuity
Feed a previous generation back in so the next frame shares the same subject.

Edit
New background
Keep the person’s face, hair, and pose. Replace the background with a bright concrete studio and a soft shadow on the floor. Do not change the outfit.
Product
Product in a room
Keep the product shape and label. Place it on a walnut table beside a window, morning light from the left, no extra objects.
Style
Style only
Keep the composition and the subject’s identity. Render the same scene as a colored pencil illustration on warm paper.
關於 圖生圖 的常見問題
You upload a picture and describe how it should change. The model uses that picture as the starting point instead of inventing the subject from text alone.
