科技媒体 testingcatalog 昨日（11 月 19 日）发布博文，报道称谷歌计划本周在其 Gemini 平台，面向设计师、营销人员及教育工作者，推出名为 Nano Banana Pro 的创意升级功能。

用户可以通过 Gemini 应用中的“Thinking”模型直接访问该功能。这项升级的核心在于提供强大的布局控制能力，支持用户生成最高 4K 分辨率的图像，并自由设定从 16:9（适用于演示和印刷品）到 9:16（适用于社交媒体帖子）的多种纵横比，确保输出内容直接满足不同发布渠道的规格要求。

提示词：A cinematic, wide-angle view of Istanbul during the golden hour. In the foreground, intricate Ottoman tile patterns on a balcony railing are in sharp focus. In the background, the Hagia Sophia and the Blue Mosque dominate the skyline across the Bosporus, silhouetted against a warm, hazy orange and purple sunset. Seagulls are flying in the distance. Photorealistic, 8k resolution. —ar 2:1

提示词：A professional studio product shot of a futuristic, transparent smart-watch resting on a piece of dark slate. The watch interface is glowing holographic green. Soft dramatic lighting, 8k resolution, macro photography style, shallow depth of field. —ar 4:3

提示词：A vintage travel poster for "MARS COLONY." The main visual is a retro-futuristic biodome on a red landscape. Large, bold Art Deco typography at the top says "VISIT MARS," and smaller text at the bottom says "The Red Planet Awaits You - Est. 2050." Texture of worn paper. —ar 2:3

（上图为优化阅读，经过裁剪，实际比例为 1:1）提示词：A sophisticated, minimalist logo centered on a white background. The word "FRESH" is spelled out using realistic, glistening slices of kiwi and strawberry. High contrast, sharp focus, professional food photography style. —ar 1:1

提示词：A high-resolution, professional infographic map of Europe. The map should be topographical, showing mountain ranges in relief. Clear, sharp text labels should identify major capitals: "Paris", "Berlin", "Rome", "Madrid", and "Warsaw". The ocean should be a deep matte blue, and the land should be in natural earth tones. Clean, modern typography suitable for a textbook. —ar 4:3

新功能的一大突破是引入了“高级文本渲染”技术。该技术大幅提升了图像中文字和拼写的精准度，能够清晰地生成包含复杂文本的海报、菜单、邀请函甚至数据密集型信息图。

提示词：Create a wide infographic titled "How Solar Power Works" with a clean flat design. Include: a sun icon, solar panel diagram, arrows showing energy flow to a house and battery, four numbered steps with short captions, and a comparison bar chart of "Day vs Night usage". —ar 16:9

同时，Nano Banana Pro 还优化了概念设计流程，用户只需上传一张二维草图，即可通过提示词让 Gemini 将其渲染为具有照片级真实感的三维产品图像，便于探索不同材质和光影效果。

提示词：“A clean, 3D isometric visual explainer of a "Smart Home Ecosystem." Show a cross-section of a house with icons connecting different devices: a thermostat, a smart fridge, and security cameras. Use a pastel color palette with soft lighting. —ar 16:9

在图像编辑与合成方面，Nano Banana Pro 也实现了显著增强。它支持用户同时上传多达六张图片进行场景融合或元素提取，极大地丰富了创作的可能性。

IT之家援引博文介绍，其中，“风格迁移”功能可以将参考图像的调色板或整体视觉风格应用到另一张照片上。更具创新性的是“画布引导”功能，允许用户直接在上传的图片上通过涂鸦、画圈或注释等方式下达视觉指令，让 AI 更直观地理解并执行修改意图。

与早前发布的版本相比，Nano Banana Pro 的核心价值在于将多图像合成、高可靠性排版以及纵横比控制等关键功能整合进单一工作流中。这一集成化设计有效减少了创作者在不同专业软件之间来回切换的繁琐操作，显著提升了工作效率。
