Do you have any pointers for dialing in PAG? What am I looking for visually to determine an increase/decrease in PAG?
PAG is effectively an extra cfg done over positive prompt and increasing scale equals to increasing positive prompt strength
16:50:50
@a:noevil.pl@a:noevil.plRegular cfg performed like negative + (positive - negative) * cfg16:51:05
@a:noevil.pl@a:noevil.pl * Regular cfg performed like pred = negative + (positive - negative) \* cfg 16:52:44
@a:noevil.pl@a:noevil.pl * Regular cfg performed like pred = negative + (positive - negative) * cfg 16:52:47
@a:noevil.pl@a:noevil.pl PAG is pred + (positive - pag) * scale 16:53:25
@a:noevil.pl@a:noevil.pl * PAG is pred = pred + (positive - pag) * scale 16:53:39
@a:noevil.pl@a:noevil.pl Where pag is the positive modeled with middle block disabled 16:54:19
@a:noevil.pl@a:noevil.plIt does not mean final cfg equals cfg + scale but you will notice image getting more saturated as you increase scale16:55:11
@a:noevil.pl@a:noevil.plBut decreasing cfg might actually let you go for higher scale values16:55:58
@a:noevil.pl@a:noevil.plI should read paper about why doing that extra guidance with skipped blocks improves quality16:56:35
@a:noevil.pl@a:noevil.plRecent changes allow you to perform the same trick over DiT models (including stable audio)16:57:05

Oh and if your cfg is low enough you will also notice negative prompt becoming weaker obviously

@_discord_1179480253907882178:t2bot.io it goes well with SEG 17:20:30
