文章介绍了Stable Diffusion大模型推出的两种提速技术Turbo和LCM,虽然能缩短出图时间,但存在明显的画质损失。随着字节跳动团队SDXL-Lightning大模型的发布,因其画质损失小,迅速被知名大模型跟进更新。文章强调了技术迭代对硬件资源的节约和缓解高端算力卡断供情况的重要性,并展示了多个使用大模型生成的图片示例。最后提供了下载链接和出处。
几个月前,Stable Diffusion的大模型连续推出了两中提速技术,一个是官方的Turbo,一个是清华团队的LCM。
都能在5-8步实现出图效果,把出图时间缩短了5-10倍。
但是,除了Dreamshaper等少数几个大模型坚决跟进外,大部分大模型都还在坚持原有的技术,没有彻底转投Turbo和LCM。
原因很简单,现阶段Turbo和LCM速度是快了,但有明显的画质损失。很多AI绘画爱好者对画质的要求比较高,这两种技术满足不了。
而一些喜欢创作视频的爱好者早早转移到了这两种技术,在画幅足够大的情况下,单帧轻微画质损失不会影响视频效果。
随着字节跳动团队SDXL-Lightning大模型的发布,一夜之间知名大模型都迅速跟进更新了Lightning版本。
为什么?
因为Lightning画质损失非常小,在6-8步左右的时候,肉眼几乎分辨不出任何画质损失。
C站下载量最大的SDXL模型Juggernaut XL,在SDXL-Lightning发布后的第三天,发布了Lightning版本。
作者称:
Juggernaut 可在 RunDiffusion 上的新 Auto1111 Forge 上使用。
JuggernautXL V9 + RunDiffusion Photo 2 在 Hugging Face 上。
Juggernaut + RunDiffusion Photo2 Lightning 4 Steps 在 Hugging Face 上。
对于版本 9,我要特别感谢 RunDiffusion(照片模型)和 Adam,他们 diligently 帮助我测试 :)(给他们留些爱 ;))
我回来得真是太快了 :D
这次我会少说一些。在过去两个月里,不断有人要求检查 Turbo 和/或 LCM 选项。然而,我对这两个选项都不是很确信。在我看来,Lightning LoRA 似乎更成熟一些,在测试中,这三种选择中,它最终带来了最好的结果。另外,在这里我不必更改许可证,这对我来说,对你来说,都是一个额外的优点 :)
最后,我决定采取 4 个步骤的 LoRA 的第一步,并将其与 Juggernaut V9 合并。然而,我可能在接下来的几天里也会发布 8 个步骤的版本。关于基本质量,我仍然推荐完整的 V9 检查点,以获得最佳可能的质量。但对于硬件功率较弱的人来说,这个版本会给他们带来好处,他们能够快速生成图像:)所以,如果你还没有体验过 Juggernaut,这可能是一个完美的机会 :)
果然,连精益求精的大模型创作者都选择了Lightning路线。
让我们迎来Lightning时代吧!
技术的迭代也给了我一个很大的启示:硬件上的差距也许可以用软件技术来弥补。
SDXL大模型刚发布的时候,几乎淘汰了所有12G以下的小显存用户,但comfyUI等工具通过技术手段,支持到8G显存甚至6G显存,但在低配置的显卡上,庞大的模型带来漫长的出图时间。而Lightning技术的出现,又把SDXL大模型的门槛降到和SD1.5差不多,出图速度甚至远远快于SD1.5。节约了大量的显卡资源。
中国现在面临高端算力卡断供的情况,一定程度上也可以通过类似软件技术的迭代来缓解。
还是专心画图吧~~~
