The generator is frequently updated but this is what we know for now (based on all the different topics here about it):
-the "style" add some prompts and negative prompts to your own prompt, so you have to add it on your prompt on automatic1111, you can find them here: https://perchance.org/t2i-styles#edit
-the model is different depending on the prompts/style, for example realistic vision (it is confirmed), and maybe deliberate v2 are alternatively use for photo related images (mainly realistic vision since an update made one month) ,and I think deliberatev2 is use for other kind of styles too (it is a very versatile model). But it was used for sure because someone find it on previous jpeg files properties . I think it is still used. We don't know if other models are used for other styles
-sampling method : it seems it is Euler A, that is what someone find on previous jpeg files properties too
-sampling steps: no more than 20
-"no loras, no embeddings, no fancy sampler stuff, no hi-res fix, no hidden ‘quality’ prompts" (from @perchance@lemmy.world )
-BUT (and this is the "problem" lol) "there is hidden stuff to reduce suggestive/nudity/etc." (this is the words of the owner of @perchance@lemmy.world)
And THIS (the hidden stuff) is why we just can not reproduce the perchance text2img generator locally on automatic1111 I think, even if we use realistic vison or deliberatev2 with the right sampling method/steps, the exact same prompt and style prompts. Stable diffusion is very very sensitive to very small change (just change one word on a prompt and the images can be very different). Even the resolution change the result (portrait vs landscape). So without this "hidden stuff" and other settings we don't know, it is for now impossible to reproduce it ... I tried to add negative prompts like "nsfw" or "porn" and things like that but it doesn't repoduce the perchance generator.
So we really hope he will give us all settings (in fact it can be explained in two minutes ^^) and so we will stop to bore him with that lol
to upvote the topic/comment can help ^^
