谷歌在其地球网页版中推出了基于Nano Banana 2模型的图像生成功能，但这项新功能在发布不到一天后被紧急撤回1。该功能允许用户通过点击"Create image"按钮，在真实地理位置上根据文本提示生成AI定制化图像1。
Nano Banana 2采用了"地理空间约束"技术，融合了Gemini多模态能力与搜索增强功能1。生成单张图像需耗时长达两分钟1。该模型在Arena排行榜上排名第五，落后于OpenAI的GPT-image-21。谷歌利用二十年积累的卫星影像、航拍照片及覆盖40多国的3D地形建模作为差异化优势1。
功能的技术底层由三部分组成：物理底图实时捕捉、世界知识库实时检索，以及高保真细节与精确文本渲染1。原计划中，这一功能支持历史重现、虚拟导游、房地产规划和建筑可视化等应用场景1。谷歌承诺在加强防护措施后重新发布该功能1。
Google has withdrawn an artificial intelligence image generation capability from Google Earth's web version shortly after its introduction 1. The feature, which integrated the Nano Banana 2 model, allowed users to generate customized images at real geographic locations by clicking a "Create image" button and entering text prompts 1.
The technology leveraged Google's proprietary "geospatial constraint" system, which combined real-time physical base maps, live world knowledge retrieval, and high-fidelity detail rendering with precise text generation 1. Each image could take up to two minutes to produce 1. The feature promised applications ranging from historical recreation and virtual tours to real estate planning and architectural visualization 1. Google's competitive advantage stemmed from two decades of accumulated satellite imagery, aerial photography, and 3D terrain modeling covering over 40 countries 1.
The function was removed less than a day after launch 1. Google has committed to implementing enhanced safeguards before reintroducing the capability 1. At the time of withdrawal, Nano Banana 2 ranked fifth on the Arena leaderboard, behind OpenAI's GPT-image-2 1.
