FLUX模型简介
如果昨天你关注了AI绘画圈子的动态，应该对“FLUX”这个名字印象深刻。这款由Stable Diffusion原始团队 Black Forest Labs 推出的文生图模型，堪称一匹黑马——它拥有迄今最大的开源体量：120亿参数，权重文件高达23.8G。
这家技术实力雄厚、已获3100万美元种子轮融资的团队，一口气推出了三个版本：面向开发者的 FLUX.1-dev（原始20步开源版）、追求速度的 FLUX.1-schnell（蒸馏4步开源版），以及需要通过API调用的闭源 FLUX.1-pro。考虑到多数消费级显卡的显存压力，社区也迅速推出了对应的FP8量化版本，让更多人有机会尝鲜。

那么，FLUX究竟强在哪里？来看几个核心亮点：
- 图像质量与分辨率突破：它能够以更高分辨率直接生成震撼的视觉效果，并且原生支持任意宽高比出图。在多项美学评分中，其表现甚至超越了SD3和Midjourney 6。
- 逼真的人体与写实感：实现了高度逼真且在解剖学上精确的人体描绘，照片真实感提升显著。
- 终结“多指怪”难题：这是AI绘画的老大难问题。FLUX在直出时，生成完美手指、脚趾的概率大幅提高，畸形情况明显减少。
- 精准的提示跟随与文字渲染：对于复杂英文提示词的理解和遵循能力精准，同时还能较好地处理画面中的英文文字渲染。

Flux模型体验
Flux ComfyUI安装
好消息是，ComfyUI的最新版本已经支持运行Flux模型了。只需要将你的ComfyUI更新到最新版，并准备好相应的模型文件即可。具体操作指南，官方文档写得非常清楚。
安装过程其实就三步，关键在于把文件放到正确的位置：
- 第一步，下载Flux1-schnell.sft或flux1-dev.sft模型，放到ComfyUI/models/unet/目录下。如果显存不足24G，强烈建议使用8位量化版本，链接也已备好。
- 第二步，下载VAE模型ae.sft，放置到ComfyUI/models/vae目录。
- 第三步，下载T5文本编码模型t5xxl_fp8_e4m3fn.safetensors和clip_l.safetensors，放到ComfyUI/models/clip目录。
