同一条提示词，真实出图——不挑图
我们用入门档位（1K / Basic）在两个模型上各跑了一次每条提示词，保留第一次的结果。下面就是原样返回的图。
第一回合——海报排版
提示词: A retro travel poster with the headline "VISIT KYOTO" in large elegant serif type at the top and the tagline "Old streets, new stories" below it, a torii gate at sunset, warm oranges and deep reds, clean vintage print style
两个模型每个单词都拼对了。Nano Banana Pro 选择了扁平复古印刷插画风；Seedream 5 Pro 则是照片底加文字的写实海报。这是风格差异，不是质量差距。
第二回合——写实人像
提示词: A photorealistic close-up portrait of an elderly fisherman with weathered skin and a gray beard, golden hour light on his face, shallow depth of field, visible skin texture and fabric detail on his wool sweater
两张都能以假乱真。Nano Banana Pro 近看皮肤纹理和毛孔级细节更重；Seedream 5 Pro 更偏温暖的电影感日落色调。
第三回合——热闹市集
提示词: A busy Saturday farmers market from a slightly elevated angle: at least eight distinct stalls with fruit, flowers, bread, and cheese, dozens of people browsing, string lights overhead, every stall sign readable, rich detail everywhere
有点意外：Nano Banana Pro 把每个摊位招牌都画得清晰可读，Seedream 5 Pro 人群更密，但有个别招牌文字发抖。密集场景的差距比参数表暗示的更小。
第四回合——带标注的信息图
提示词: A product infographic for a smartwatch on a clean white background: the watch centered, four labeled callout lines pointing to the screen, strap, sensor, and button, each label short and readable, minimal tech aesthetic
Nano Banana Pro 一字不差地执行了四个标注的版式计划；Seedream 5 Pro 给出了更简约、带图标的排版。两张都清楚——按口味选。
