This success is largely attributed to the use of class- or text-conditional diffusion guidance methods, such as classifier and classifier-free guidance. In this paper, we present a more comprehensive perspective that goes beyond the traditional guidance methods. From this generalized perspective, we introduce novel condition- and training-free strategies to enhance the quality of generated images. As a simple solution, blur guidance improves the suitability of intermediate samples for their fine-scale information and structures, enabling diffusion models to generate higher quality samples with a moderate guidance scale. Improving upon this, Self-Attention Guidance (SAG) uses the intermediate self-attention maps of diffusion models to enhance their stability and efficacy. Specifically, SAG adversarially blurs only the regions that diffusion models attend to at each iteration and guides them accordingly. Our experimental results show that our SAG improves the performance of various diffusion models, including ADM, IDDPM, Stable Diffusion, and DiT.

This success is largely attributed to the use of class- or text-conditional diffusion guidance methods, such as classifier and classifier-free guidance. In this paper, we present a more comprehensive perspective that goes beyond the traditional guidance methods. From this generalized perspective, we introduce novel condition- and training-free strategies to enhance the quality of generated images. As a simple solution, blur guidance improves the suitability of intermediate samples for their fine-scale information and structures, enabling diffusion models to generate higher quality samples with a moderate guidance scale. Improving upon this, Self-Attention Guidance (SAG) uses the intermediate self-attention maps of diffusion models to enhance their stability and efficacy. Specifically, SAG adversarially blurs only the regions that diffusion models attend to at each iteration and guides them accordingly. Our experimental results show that our SAG improves the performance of various diffusion models, including ADM, IDDPM, Stable Diffusion, and DiT. Moreover, combining SAG with conventional guidance methods leads to further improvement."),Ka.forEach(a),Xa.forEach(a),lt=d(t),_e=o(t,"P",{});var en=i(_e);Ut=l(en,"Resources:"),en.forEach(a),ct=d(t),b=o(t,"UL",{});var $=i(b);be=o($,"LI",{});var Ba=i(be);Q=o(Ba,"A",{href:!0,rel:!0});var tn=i(Q);It=l(tn,"Project Page"),tn.forEach(a),Ct=l(Ba,"."),Ba.forEach(a),Jt=d($),ve=o($,"LI",{});var La=i(ve);Y=o(La,"A",{href:!0,rel:!0});var an=i(Y);jt=l(an,"Paper"),an.forEach(a),Nt=l(La,"."),La.forEach(a),Bt=d($),ye=o($,"LI",{});var Za=i(ye);X=o(Za,"A",{href:!0,rel:!0});var nn=i(X);Lt=l(nn,"Original Code"),nn.forEach(a),Zt=l(Za,"."),Za.forEach(a),Wt=d($),we=o($,"LI",{});var Wa=i(we);K=o(Wa,"A",{href:!0,rel:!0});var on=i(K);Ft=l(on,"Hugging Face Demo"),on.forEach(a),Vt=l(Wa,"."),Wa.forEach(a),zt=d($),Se=o($,"LI",{});var Fa=i(Se);ee=o(Fa,"A",{href:!0,rel:!0});var sn=i(ee);qt=l(sn,"Colab Demo"),sn.forEach(a),Ht=l(Fa,"."),Fa.forEach(a),$.forEach(a),dt=d(t),k=o(t,"H2",{class:!0});var bt=i(k);L=o(bt,"A",{id:!0,class:!0,href:!0});var rn=i(L);Ce=o(rn,"SPAN",{});var ln=i(Ce);w(te.$$.fragment,ln),ln.forEach(a),rn.forEach(a),Ot=d(bt),Je=o(bt,"SPAN",{});var cn=i(Je);Rt=l(cn,"Available Pipelines:"),cn.forEach(a),bt.forEach(a),ft=d(t),Z=o(t,"TABLE",{});var vt=i(Z);je=o(vt,"THEAD",{});var dn=i(je);U=o(dn,"TR",{});var Pe=i(U);Ne=o(Pe,"TH",{});var fn=i(Ne);Qt=l(fn,"Pipeline"),fn.forEach(a),Yt=d(Pe),Be=o(Pe,"TH",{});var pn=i(Be);Xt=l(pn,"Tasks"),pn.forEach(a),Kt=d(Pe),Ae=o(Pe,"TH",{align:!0});var un=i(Ae);ea=l(un,"Demo"),un.forEach(a),Pe.forEach(a),dn.forEach(a),ta=d(vt),Le=o(vt,"TBODY",{});var hn=i(Le);I=o(hn,"TR",{});var xe=i(I);Ze=o(xe,"TD",{});var mn=i(Ze);ae=o(mn,"A",{href:!0,rel:!0});var gn=i(ae);aa=l(gn,"StableDiffusionSAGPipeline"),gn.forEach(a),mn.forEach(a),na=d(xe),We=o(xe,"TD",{});var _n=i(We);Fe=o(_n,"EM",{});var bn=i(Fe);oa=l(bn,"Text-to-Image Generation"),bn.forEach(a),_n.forEach(a),ia=d(xe),Ge=o(xe,"TD",{align:!0});var vn=i(Ge);ne=o(vn,"A",{href:!0,rel:!0});var yn=i(ne);sa=l(yn,"\u{1F917} Space"),yn.forEach(a),vn.forEach(a),xe.forEach(a),hn.forEach(a),vt.forEach(a),pt=d(t),C=o(t,"H2",{class:!0});var yt=i(C);W=o(yt,"A",{id:!0,class:!0,href:!0});var wn=i(W);Ve=o(wn,"SPAN",{});var Sn=i(Ve);w(oe.$$.fragment,Sn),Sn.forEach(a),wn.forEach(a),ra=d(yt),ze=o(yt,"SPAN",{});var An=i(ze);la=l(An,"Usage example"),An.forEach(a),yt.forEach(a),ut=d(t),w(ie.$$.fragment,t),ht=d(t),J=o(t,"H2",{class:!0});var wt=i(J);F=o(wt,"A",{id:!0,class:!0,href:!0});var Gn=i(F);qe=o(Gn,"SPAN",{});var Dn=i(qe);w(se.$$.fragment,Dn),Dn.forEach(a),Gn.forEach(a),ca=d(wt),He=o(wt,"SPAN",{});var Pn=i(He);da=l(Pn,"StableDiffusionSAGPipeline"),Pn.forEach(a),wt.forEach(a),mt=d(t),h=o(t,"DIV",{class:!0});var v=i(h);w(re.$$.fragment,v),fa=d(v),Oe=o(v,"P",{});var xn=i(Oe);pa=l(xn,"Pipeline for text-to-image generation using Stable Diffusion."),xn.forEach(a),ua=d(v),le=o(v,"P",{});var St=i(le);ha=l(St,"This model inherits from "),De=o(St,"A",{href:!0});var En=i(De);ma=l(En,"DiffusionPipeline"),En.forEach(a),ga=l(St,`.
