Hey you and welcome I'm Mr. Berry and with us in the studio again is Ushi my pet dog
well last video we made was about night Cafe and adding text this time we're
going to be doing something else with night Cafe and uh the question came up
what happens if you use the same seed the same prompt but you change only the model diffusion
number now not Cafe has a number of different diffusion models that you can actually use from
and as you can see here they go from 1.4 all the way to 2.1 but then there's also
others there the in painting that one is used only when you're using a mask but then there's
another one there that the sdxl that's brand new and that one I want to try that one out as well
and see how it differs from the other diffusion models so in this we're going to be using the
exact same prompt and the same seed number and see how just changing the diffusion model will
change the overall effect on the image give you kind of a better idea of if you want a different
effect on a particular type of image that you're creating in artificial intelligence all right so
we'll figure out how to do that there and show you the results so let's take a look [Music]
so let's go over a quick definition of the stable diffusion model
stable diffusion is an algorithm that has multiple models to choose from models can differ from each
other in a few ways but most commonly they're trained on different data which means some models
are better on certain props than others the latest stable diffusion model is sdxl which is 2.5 times
bigger than the original stable diffusion models making it more capable and generally more coherent
including a start image and mask will automatically use the stable and painting version
2.0 model but you may override that setting stable diffusion in painting is a latent text
to image diffusion model capable of generating photorealistic images given any text input
with the extra capability of in painting the pictures by using a mask
so here we are in the create page at night Cafe and I have the prompt up already and I
have multiple prompts I'm using for this one I'll be doing again with just using a single
prompt because sdxl does better with a single prompt and we're starting with stable diffusion
1.4 as you can see here and so the prompts we have would be uh these right here so I have
Milky Way galaxy over a garden breathtaking artwork by Ansel Adams colorful sky and all
that so I have a number of different prompts I've used this is actually one of the patterns
that I I like or one of the prompts that I like to use is are actually all of these in one shot
so I'm taking a look at these and
let's look at the result so this is the result there from 1.4 as you see it's beautiful
now let's do it with 1.5 and as you can tell we're using the exact same seed so you have the Mount St
mountains in the background there as I compare them back and forth go back and forth on those
now let's go to 2.0 and 2.0 does look very different compared to
the 1.5 that we were just looking at there
a little bit similar in the mountains but now we have a lake or an ocean and 2.1 so remember
we're using the exact same prompts and the same seed we're only changing the diffusion model and
the appearance is that different so it gives you a way to kind of fine tune your Creations there
let's look at the next one wow the version 2.0 768 PX looks absolutely stunning in this pattern here
we have a valley with mountains and a sitting sun again same seed same prompts and here's 2.1 768 PX
very very similar as the other one you have these lavender flowers here in the foreground
but the Valley now has a river or a lake in it wow this is beautiful and here's sdxl it's very
different just let you know sdxl does not do very well with multiple props and that's why
I'm going to do it again with a single prompt on the next go around here but uh here it has
a bedroom with now a poster in the background of like a Galaxy over a garden which is kind
of different than all the others now let's just compare all of them back to back in short order
and for this next segment I'm going to be using the exact same prompt but this
time it'll be only one single prompt and it'll be fairy floating holding flowers
nothing else in there and we'll be starting with 1.4 the seed this time let's see what
seed we'll be using the seed number 18 and here's the result for version 1.4 version 1.5
version 2.0 and version 2.1 and here we see version 2.0 768px and then version 2.1 768 PX
and finally sdxl which actually came out very good
hey those are surprising results that we got out of there and it's kind of interesting that
the newer versions there it had that different effect there almost uh almost like a paint effect
on it whereas the other ones there had more of a photographic appearance to them so it's kind
of interesting how it changed with each different diffusion model now when I'm creating art a lot
of times I'll use I'll just experiment with using different diffusion models and even I'll change
my prompt slightly to try to get the effect that I want of a particular challenge because night
Cafe every day they have a different Challenge and you have to create an image with that type
of theme that they're looking for so that you can win uh their their prize their daily prize there
all right hey if you like these types of videos please give it a thumbs up comment down below if
you have an idea or a question on technology or anything else they're related to technology and
I'll make a video about that to answer those and if you haven't done so already please subscribe
to my channel and a big thank you to all those who have subscribed to my channel and who are
sharing my videos on their social media and here's ushi she's going to say thank you to
everyone for watching the video all the way to the end all right well you have a good day bye bye!
