Playground v2.5 模型界的“美学天花板”？| AI绘画教程

前不久，playground发布了他们的V2.5版模型，那么有很多的人都在说，这个模型是开源模型中的“美学”天花板！

Playground自己也将“审美”一词（aesthetic）放在了模型名称的结尾，可见，他们自己对模型出图的审美质量非常自信！

那么，我们今天就来对比测试一下，到底所谓的“审美天花板”是名副其实，还是名不副实！

我们在huggingface可以将这个模型下载下来，如果说你的显卡支持半精度模型的话，你就下载上面这个6.94G的模型，如果你的显卡不支持半精度模型，你就下载下面这个13.9G的模型！

另外，目前只有ComfyUI支持该模型，automatic1111还无法正常运行该模型，我们将下载下来的模型放在checkpoint大模型同一个文件夹下面即可！

在这里，我做了一个对比评测不同checkpoint的工作流，用同样的提示词，同样的宽高比，上面这一组加载的是playground V2.5模型，下面这一组加载的是我常用的一个SDXL模型，如果是本频道铁粉的都应该知道，该模型多次出现在我之前的视频中！这足以说明该模型在SDXL模型中是非常具有代表性的，它的出图质量也非常好！

为了更客观、更全面地比较2个模型，我这里收集了10条不同的提示词，分别来自于Midjourney和C站。

我们先一起将这10条提示词都跑完，然后集中来对比playground V2.5 和 SDXL模型出图的审美质量做对比！
