生成前先看已核验事实
以下信息来自当前产品配置与所链接的一手文档。实际输出质量仍会受提示词与输入图像影响。
- Google model family
- Gemini 3 Pro Image
- Banananano route
- Kie.ai · nano-banana-pro
- Input workflows
- Text + reference images
- Documented output
- Up to 4K
Google describes Nano Banana Pro as its professional image model for complex instructions and asset production.
This is the provider and model identifier configured in the live generator—not a direct Google API connection from your browser.
The product enables image input for this model. Reference quality and rights still determine whether an edit is usable.
Google documents 1K, 2K, and 4K output options. The service shows the available resolution and credit estimate before generation.
最适合稳定的创意生产
当你需要在多次生成中保持产品、脸部、服装或品牌风格稳定时，Nano Banana Pro 是更稳的起点。
- 拥有可复用视觉风格的产品营销图
- 角色头像与创作者形象
- 需要精致灯光和构图的广告概念图
如何写提示词
给模型清晰的主体、画面格式、镜头或灯光方向，以及最终用途。把提示词当成一份精简的创意简报。
- 先说明素材类型：产品图、人像、海报、缩略图
- 明确限制：颜色、背景、角度、文字区域
- 最后加入质量方向：编辑感、影棚、4K、商业用途
A fair way to evaluate Nano Banana Pro
Use a fixed brief and a fixed reference set. Compare the results on the job you actually need instead of relying on a single attractive sample.
- 1Write one brief with five scored requirements: subject, layout, reference fidelity, text intent, and publishability.
- 2Generate at least three independent results with the same model, aspect ratio, resolution, and input images.
- 3Review every result at full size; record failures instead of selecting only the best-looking image.
- 4Repeat the identical setup with another available model, then compare median—not best-case—performance.
We have not published a controlled output benchmark on this page, so we do not claim that Pro wins every task. The image above is illustrative, not proof of a measured result.
