<p></p><h2>背景</h2><p><font size="3">Google Gemini 2.5 Nano Banana(官方名称为 <strong>Gemini 2.5 Flash Image</strong>)是谷歌于 2025 年 8 月推出的革命性 AI 图像生成与编辑模型,凭借其多模态架构、角色一致性和实时协作能力,重新定义了 AI 视觉内容创作的标准。采用统一的 Transformer 架构,原生支持文本与图像的无缝融合,无需中间转换步骤。例如,用户可直接通过自然语言指令(如 “将这张照片改为复古港风,背景换成 80 年代香港街头”)实现复杂编辑,模型能精准对齐语义与视觉元素,避免传统模型的信息丢失问题。内置 Gemini 家族的全球知识库,可理解物理原理(如光影反射、透视关系)和文化语境。例如,生成 “巴黎铁塔夜景中的产品图” 时,模型会自动匹配环境光色温与产品表面反光效果,确保物理真实性。</font></p><p><font size="3"><strong>99% 面部特征保留</strong>突破性的 “全局外观 Token + 局部细节 Token” 双重约束机制,可在不同场景、光线和服装变化中保持人物、宠物甚至产品的外观一致性。</font></p><p><font size="3">支持连续多轮修改,用户可逐步细化需求(如先模糊背景,再调整姿势,最后添加道具),模型全程保持上下文记忆,避免传统工具的 “断层式” 修改。<br>提供 Gemini API、Google AI Studio 等接入方式,支持 Python、JavaScript 等主流语言,开发者可快速集成到电商平台、教育工具或设计软件中。例如,电商网站可通过 API 自动生成多场景产品图。</font></p><p></p><h2>提示词</h2><blockquote><p>{<br>   "style": "High-key studio portrait, direct flash aesthetic, East Asian social media style (e.g., Ulzzang, Douyin), stylized beauty retouching.",<br>   "output": {<br>     "color_profile": "sRGB",<br>     "render_intent": "photo"<br>   },<br>   "subject": {<br>     "category": "human",<br>     "gender_presentation": "female",<br>     "ethnicity": "East Asian (e.g., Korean, Chinese)",<br>     "age_bracket": "young_adult",<br>     "body": {<br>       "build": "slim",<br>       "proportions": "natural human anatomy",<br>       "posture": "relaxed on sofa, seated casually",<br>       "pose": "seated, legs crossed and tucked close to body",<br>       "gesture": "Right hand raised, fingers loosely curled, back of fingers/knuckles gently supporting the chin and lower cheek.",<br>       "head_tilt_deg": 5<br>     },<br>     "face": {<br>       "expression": "Playful, alluring",<br>       "gaze": "right eye direct to camera",<br>       "eye_action": "winking with the left eye",<br>       "skin_tone": "Very pale porcelain (lightened aesthetic)",<br>       "makeup": "Stylized K-Beauty/Douyin look: flawless matte base, strong pink blush high on cheeks, pink gradient lips, defined brows, light eyeliner, emphasized Aegyo-sal",<br>       "features": "small beauty mark/mole under the left eye"<br>     },<br>     "hair": {<br>       "length": "long",<br>       "style": "messy high updo/bun with loose strands and curtain bangs",<br>       "color": "dark brown"<br>     },<br>     "wardrobe": {<br>       "top": "white fitted cropped camisole",<br>       "outerwear": "light gray zip hoodie, worn open and slightly slipping off both shoulders",<br>       "bottom": "white lounge shorts with drawstring",<br>       "footwear": "barefoot"<br>     }<br>   },<br>   "environment": {<br>     "location": "studio or minimalist interior",<br>     "set": "black leather sofa against a plain white or light gray wall",<br>     "props": "Silver laptop (Apple MacBook, logo visible) placed on the cushion to the subject's right (camera left)"<br>   },<br>   "lighting": {<br>     "key": {<br>       "source": "strobe/flash",<br>       "modifier": "Bare reflector or direct flash (hard source)",<br>       "position": "Near camera axis, slightly camera-right and above eye line",<br>       "effect": "Crisp, dark, well-defined cast shadows on the wall directly behind subject;
