About Gemini 3.1 Flash Lite Image

换一种颜色、去掉一件道具、做一个贴纸,这些小任务不需要每次重做复杂设计。Gemini 3.1 Flash Lite Image,也叫 Nano Banana 2 Lite,侧重低延迟的图片生成与多轮局部编辑,适合把图片工具嵌入日常沟通和轻量创作中。

上传现有图片后,可以明确指定某个物体换色、简化背景或调整局部;从文字开始,也能制作简单插画、装饰图和贴纸方向。把任务限定在一个清楚的目标上,更容易快速判断效果,例如只比较手机壳的颜色,或者只调整人物身后的背景。

这个版本专注 1024px 的 1K 输出,不提供 2K、4K。它适合小尺寸展示、创意草图与交互式修改;如果素材要用于大幅海报或高细节成片,应选择更适合高分辨率交付的图像模型。生成内容也没有搜索辅助,真实标识、产品信息和文案需由你提供。

Use cases and prompting

给手机壳试三种配色

保留参考图中手机壳的形状、摄像头开孔和表面纹理,只把壳体颜色改成浅紫色。保持原来的白色背景、角度和阴影,不添加图案、文字或配件。

下一轮再只改成薄荷绿,逐张比较哪种颜色更适合产品。

适合哪类改图? 配色、背景和少量局部元素的快速调整,目标越清楚越容易比较。

能直接做 4K 成片吗? 这个版本只提供 1K,清晰细节和大尺寸输出需选择其他模型。

改色后产品轮廓也变了怎么办? 限定只改颜色,重新使用原图,并仔细检查开孔、边缘和阴影。
