要说近期AI圈里最红的，应该就是来自谷歌的Gemini-2.0-flash-exp-image-generation。我们可以简单理解它为是一个图像编辑模型，gemini-2.0-flash-exp-image-generation可以结合了多模态输入、增强版推理以及自然语言理解来进行图像生成，还能够通过自然语言对话直接对图像进行修改。
这种把传统的语言大模型和图像生成模型结合的方式，让用户无需掌握复杂的图像处理软件，只需简单几句提示词即可完成对图片的修改，还能保持角色和图像场景的一致性。
但其实更早之前，国内就出现了类似的产品，那就是由 Doubao 团队开发doubao-seededit。doubao-seededit可以根据用户的文字指令直接对图像进行修改，包括更换图像内容、调整风格、光照或角度等，且操作简单易用。
而在近期 ，302.AI 引入了 gemini-2.0-flash-exp-image-generation 和 doubao-seededit 两个模型，并改造成了OpenAI兼容的API格式。这样用户不仅能够通过302.AI聊天机器人直接生成使用，还可以通过API接入到第三方程序里。
接下来就带大家实测对比看看哪一模型的效果更优！
Gemini-2.0-flash vs. Doubao-seededit实测效果对比
PS：以下所有案例均由302.AI聊天机器人生成。
实测1：一键生成图文博客
提示词：给我写一个做可乐鸡翅的教程，带图片
对比结果：gemini ＞ doubao
虽然gemini生成的图文教程存在瑕疵，但是模型本身可以输出多张图片+文字，相当惊艳。而doubao模型没有这个功能，所以gemini更胜一筹。
gemini：成功生成了图文并茂的美食教程，但生成的教程配图出现的人物关节位置较不自然。
doubao：doubao-seededit原并不支持生成图片，以下所呈现的效果是302.AI为自动调用即梦2.1模型后所生成的。
实测2：消除路人
提示词：请帮我消除背后的路人
原图：
对比结果：gemini ＜ doubao
主要对比消除后的场景细节以及主体变化，整体来说doubao消除后痕迹更小，所以doubao胜。
gemini：背景消除后细节处理较差，而且人物的脸部发生了改变，尤其眼睛明显不协调。
doubao：消除后场景细节做得不错，脸部稍微有点变化，但没有出现五官不合理的现象。
实测3：替换背景
提示词：请将背景换成海滩
对比结果：gemini ＜ doubao
对比替换场景后与人物的融合度，doubao在保持人物一致性上不如gemini，但gemini替换后左侧脸部墨镜直接消失。
gemini：替换后场景与人物融合还可以，但物的衣服和太阳镜附近的元素没有处理干净左侧墨镜直接消失了。
doubao：替换的背景和人物还算融合，但是脸部没能保持一致性。
实测4：图片转线稿
提示词：将图片一比一转成手绘线稿
原图：
对比结果：gemini ＞ doubao
这一实测效果高下立见，doubao转换线稿风失败。
gemini：转线稿效果还不错，但可以明显看到背景元素缺失，线稿人物主体效果。
doubao：转线稿效果失败，输出的结果图片并不是线稿风。
实测5：图片添加元素和文字
提示词：在图片上水瓶的瓶身上添加文字“302.AI”。
对比结果：gemini ＞ doubao
从字体艺术感方面，doubao会更好，但可惜生成了多余的文字内容，在遵循提示词方面不够准确。
gemini：文字位置摆放正确，文字生成准确，图片色调稍微有变化，但整体来说效果很不错。
doubao：位置准确，文字也算是正确，而且字体更加有艺术感，但有多余文字内容出现，而且画面色调也轻微改变。
实测6：替换指定物品
提示词：茶杯变成蛋糕
原图：
对比结论：gemini ＜ doubao
对比替换后的整体画面协调度，gemini替换成蛋糕后阴影依旧不变，不太合理。而doubao替换后阴影形状大致与物品一致，效果整体会较好。
gemini：替换蛋糕后，画面的光影效果看起来不太协调，整体效果一般。
doubao：局部替换成蛋糕后，画面的光影看起来较自然协调的，整体效果不错。
实测总结：
综合以上实测，我们可以初步得出以下结论：
优势：
gemini-2.0-flash：可将图片转化风格、或者上传多图指定替换的物品、能支持快速生成文字及图片内容。
doubao-seededit：更适合在原图上进行局部修改，比如消除人物、将图中的某一物品替换等。
存在的局限：
gemini-2.0-flash：
（1）涉及人物五官、四肢方面的效果质量不太稳定，容易出现扭曲的情况。
（2）在图片上做局部修改细节较差，不如doubao。
doubao-seededit：
（1）替换图片的物品只能通过文字描述，无法像gemini一样通过指定替换物品图片进行。
（2）转换图片风格效果不稳定。
（3）在添加文字元素时会添加提示词外的文字。
