它不仅仅是一个画图工具，更是一个能思考、会搜索、且能原生渲染4K 画质的智能助手。 无论是对于专业创作者还是技术发烧友，这都是一把趁手的利器。

使用 Gemini（又称 Nano Banana 和 Nano Banana Pro）生成图片

import { GoogleGenAI } from "@google/genai";
import * as fs from "node:fs";
 
async function main() {
 
  const ai = new GoogleGenAI({});
 
  const prompt =
    "Create a picture of a nano banana dish in a fancy restaurant with a Gemini theme";
 
  const response = await ai.models.generateContent({
    model: "gemini-2.5-flash-image",
    contents: prompt,
  });
  for (const part of response.candidates[0].content.parts) {
    if (part.text) {
      console.log(part.text);
    } else if (part.inlineData) {
      const imageData = part.inlineData.data;
      const buffer = Buffer.from(imageData, "base64");
      fs.writeFileSync("gemini-native-image.png", buffer);
      console.log("Image saved as gemini-native-image.png");
    }
  }
}
 
main();

城市渲染数字艺术海报 (来源 @op7418) 模型：Nano banana

提示词：一张针对 [城市名称] 的城市渲染数字艺术海报。

画面核心主体是一个漂浮在白云上方、形状像所选城市的并且占据画面大部分内容的微型岛屿。岛屿的形状与城市在地图上的形状相似，无缝融合城市独特的标志性地标、自然景观及文化元素。加入城市特有的鸟类、电影般的光影、鲜艳色彩、航拍视角和阳光反射效果，建筑不宜太多太密集。

岛屿展现历史与现代的无缝融合。一部分是该城市最具代表性的古代历史建筑；另一部分平滑过渡为城市的地标建筑和天际线景观。

岛屿漂浮浩瀚云海之上。云海采用该城市所在文化圈的传统艺术风格进行表现。

立体城市拼音或英文名的 3D 文字漂浮在微型岛屿的上方，这组文字像一个生态与文化共生的微缩生态装置。

在画面四周和主体周围，叠加一层极简、高雅、具有博物馆展板质感的信息排版层。主要检索相关的城市信息，主要信息使用经典的衬线字体，辅助数据可使用极细的极简无衬线体。在画面的角落，以类似古典地图集或高级杂志扉页的方式排版。用衬线体标注城市的地理坐标、别称或建城年份，以及当前的天气，作为装饰性的背景信息，整体排版留白极多，排版克制、干净、平衡，如同在欣赏一件珍贵的艺术品。

风格要求： Octane Render, C4D, Isometric City, Micro World, Living Ecosystem, 8k Resolution. DreamWorks style, 3D modeling, delicate, soft light projection.

与手机原图同框的铅笔肖像 (来源 @94vanAI) 模型：Nano banana pro

Perfect composition, highest quality, 8K resolution, soft atmosphere, professional level, award-winning style, delicate artistry.

Create an extremely detailed Japanese watercolor illustration (透明水彩) depicting a Chinese idol girl with gentle, dreamy aesthetic. The artwork features: soft transparent color washes with visible water blooms, delicate color bleeding and gradients (wet-on-wet technique), pastel color palette (soft pinks, mint greens, lavender, peachy tones), light and airy feeling with plenty of white paper showing through, subtle color layering creating luminous skin tones, loose expressive brushwork in hair with flowing strands.

The painting is rendered on high-quality cold-pressed watercolor paper (300gsm texture visible), with natural paper buckling, authentic watercolor medium characteristics including backruns, cauliflower effects, and granulation. Delicate floral elements scattered around (cherry blossoms, hydrangeas) painted in transparent washes.

In the top right corner, the date "2026.01.04" is written in soft gray watercolor with delicate brush calligraphy. The watercolor painting is placed on a clean white surface with watercolor supplies nearby (paint palette with mixed colors, brushes, water cup). An iPhone displays the reference photograph with soft natural reflections. The facial features are perfectly identical to the photo - same gentle expression, same proportions, rendered in soft watercolor style.

Soft pastel color palette: blush pink, sky blue, mint green, lavender, peach, warm beige, with lots of white paper. Romantic, gentle, fresh atmosphere with Japanese aesthetic sensibility (wabi-sabi, ma - negative space). No artist signature. 3:4 portrait orientation.
