生成由 Google Gemini 驱动的 AI 图像——从快速草图到 4K 最大细节的三个模型层次,具有角色一致性的参考图像和在创建之前规划构图的思维模式
Nano Banana 是由 Google Gemini 驱动的图像生成工具。写下你想要看到的描述,AI 会生成它——人、地方、产品、场景、艺术作品,任何你能用语言描述的东西。三个模型层次让你根据需要选择速度和质量。

Nano Banana 是快速迭代和测试想法的快速选项。Nano Banana Pro 在速度和更高质量输出之间取得平衡。Nano Banana 2 是顶级选项,具有独特的思维模式——AI 实际上在开始生成之前规划构图、照明和连贯性,产生更有意图和更精致的结果。

参考图像系统使这个工具在一致的角色工作中强大。上传多达 14 张你的角色的参考照片,标记它们,并在提示中提到这些标签。AI 使用这些参考来保持每次生成中的相同面孔、身体和风格——在数百个帖子中建立可识别的 AI 人物至关重要。

分辨率从 1K(快速草图)到 4K(最大细节)——捕捉皮肤纹理、单根头发和眼中的高光。七种纵横比覆盖每个平台格式,从方形 Instagram 帖子到垂直故事和宽幅 YouTube 缩略图。每个提示生成多达 9 个变体,以探索不同的解释,然后再做决定。
✦ Best Results Tips
📝 写场景,而不是关键词
Gemini 擅长理解自然语言。写一个叙述段落描述场景——发生了什么,环境,情绪,照明。这比用逗号分隔的关键词列表产生更好的结果。
📷 使用摄影术语以增强真实感
为了获得逼真的效果,提及相机细节——使用 85mm 镜头拍摄,黄金时段照明,浅景深,可见的皮肤毛孔。这些术语告诉 AI 模拟真实摄影而不是插图。
🖼️ 为角色提供 3 到 6 张参考图像
上传 3 到 6 张清晰的角色参考照片,分辨率为 1024px 或更高。包括不同的角度和光照条件。质量在 6 张图像左右达到平台——超过这个数量很少能改善一致性。
🧠 在 Nano Banana 2 上启用思维模式
思维模式使 AI 在生成之前规划构图和照明。虽然需要稍长时间,但产生更有意图和连贯的结果——特别是对于包含多个元素的复杂场景。
🎯 最终内容使用 4K,测试时使用 1K
在迭代提示时使用 1K 分辨率——它生成更快且成本更低。只有在对构图满意并希望发布时,才切换到 4K 以获得最大细节。
💬 提供上下文和意图
告诉 AI 图像的用途。为奢侈时尚品牌拍摄的专业 Instagram 照片与一张女性照片产生非常不同的结果——上下文塑造构图、照明和整体质量。
