This lets us identify several changes to both the sampling and training processes, as well as preconditioning of the score networks. Together, our improvements yield new state-of-the-art FID of 1.79 for CIFAR-10 in a class-conditional setting and 1.97 in an unconditional setting, with much faster sampling (35 network evaluations per image) than prior designs. To further demonstrate their modular nature, we show that our design changes dramatically improve both the efficiency and quality obtainable with pre-trained score networks from previous work, including improving the FID of an existing ImageNet-64 model from 2.07 to near-SOTA 1.55.</em>",R,h,W,y,B,d,x,ee,O,de="Pipeline for unconditional image generation.",te,u,w,ne,E,ce="The call function to the pipeline for generation.",ae,S,ue="Example:",J,I,Q,m,T,ie,A,me="Output class for image pipelines.",X,N,Y;return $=new se({props:{title:"Stochastic Karras VE",local:"stochastic-karras-ve",headingTag:"h1"}}),h=new Pe({props:{$$slots:{default:[ye]},$$scope:{ctx:G}}}),y=new se({props:{title:"KarrasVePipeline",local:"diffusers.KarrasVePipeline",headingTag:"h2"}}),x=new re({props:{name:"class diffusers.KarrasVePipeline",anchor:"diffusers.KarrasVePipeline",parameters:[{name:"unet",val:": UNet2DModel"},{name:"scheduler",val:": KarrasVeScheduler"}],parametersDescription:[{anchor:"diffusers.KarrasVePipeline.unet",description:`<strong>unet</strong> (<a href="/docs/diffusers/main/en/api/models/unet2d#diffusers.UNet2DModel">UNet2DModel</a>) &#x2014;
