About Gemini 3.1 Flash Image Preview
设计讨论里的一句“再轻快一点”，往往需要几次看图才能找到共识。Gemini 3.1 Flash Image Preview 是 Nano Banana 2 家族的预览版图像模型，适合快速生成和对话式编辑，让文字想法、参考素材与实际画面之间的往返更顺畅。
它既可以从文字开始创作，也可以理解参考图并修改背景、物体、色彩与布局。比如给线下市集做视觉，可以先生成整体气氛，再调整摊位、人物与标题；有真实商品时，则提供商品图，围绕既定外观尝试新的展示场景。每轮说明已满意的部分，以及本次只要改动的内容，便于延续同一个设计方向。
图片里的短标题、说明卡片与图文关系，也可以一起安排。明确写出文字原文和位置，控制好视觉层级，能让结果更接近真正要发布的素材。长文本、中文小字和品牌标识，仍需人工检查；如果主要目的是精确排版，可先让模型完成背景与主体，后续再添加正文。
多种画幅让同一创意能够面向封面、活动卡片或社交图片继续变化。它适合探索新的图片工作流和日常创意试验；由于是预览版本，重要的系列素材应先小范围试用，确认主体保持与修改效果，再决定是否延展整套设计。
Use cases and prompting
做一张周末市集活动图
竖版插画海报：树荫下的周末市集，三四个简洁摊位，路人轻松逛街，浅绿与奶油黄配色。顶部只写“周末逛一逛”，下方留出时间地点的位置。画面轻快，人物不过度拥挤，不添加其他招牌文字。
第一版满意后，再要求“保持构图和标题，只把插画改得更像剪纸拼贴”，比较表达方式。
修改时要重新描述整张图吗？ 不必，指出需要变动的位置，同时说明保留哪些内容。
适合连续做角色图吗？ 可以用同一参考图持续约束角色，但面部、服装和配件仍要逐张比较。
预览版适合整套活动物料吗？ 先验证一两张关键版式，再扩展，会更容易发现需要人工处理的部分。
