Given the same prompt and a seed value, how to generate the same or at least very similar images using Stable Diffusion Online and local (MS Windows) setup?

[ShamilS]

I have setup Stable Diffusion locally using [this setup instruction] (https://github.com/automatic1111/stable-diffusion-webui/wiki/install-and-run-on-nvidia-gpus).

It runs OK locally. Here is a run.bat start-up screen:

I used a sample prompt:

cute bird, happy badge, svg vector modern flat style line art color vector

and a seed value equal to 1234567 to generate images using Stable Diffusion Online and my local setup. The generated images look quite differently. Here is an online version of the generated image:

and here is the local version:

What generation parameters uses online version? If they are known and set for the local generation would the local setup generate the same image or not? Does this generation depend not only on the Stable Diffusion Model version, generation parameters but also on the hosting hardware?

@ShamilS So, one of the largest factors for repeatability will be the model you use, even more than your generation seed. (Over enough generations you will see familiar looks with your model, even with different seeds) The online version is "using the Stable Diffusion XL model" (from their FAQ). The screenshot of your offline version shows you are using the basic v1.5 model. These are are very different "libraries" of trained content. You won't be able to replicate the SDXL generation with the basic v1.5 model. There are folks that have trained the 1.5 model on images from the SDXL model to get a similar looks, but if you want to replicate exactly, you're going to need to get the same model. (Different GPU's will also introduce some variation in Seed replication, but that is an old issue you can look up). I still you SD 1.5 based models (but not the basic one) in my offline version, my GPU is not of the fan of the SDXL line. So you may run into that issue as well. Still I recommend getting a hold of the SDXL model, trying your generation again and seeing where you are then.

@w-e-w Re: automatic updates/SD3 - Do you have any expectations when the automatic update for SD3 will be available for Web.UI?

Re: similar styles for my 2 screenshots - Well, the SD Online generated bird image is looking really happy and the local one is looking sad :) Just kidding. No problem, I can agree with your statement especially taking into account that SD Online, as you noted, could use hidden prompts. I just have had the feeling that the SD Online's generated images are more elaborated because they use more advanced/better trained model, or just because they use some hidden prompts? It would, probably, never be known...

[w-e-w]

if you want to generate the exact same image then everything down to the last bit needs to be the same

if you want to generate a similar images then most of your parameters especially important ones such as the model prompts sampler scheduler needs to be the same

some other factors also have a big impact but not going to list them here

from the screenshot
I can't see what model they're using
I can't see sampler scheduler
I don't know if they use hidden prompts
not to mention any other hidden factors and potentially adding hidden prompts

we simply don't have enough information

an analogy would be
you like a painting but I don't know who painted it and did not take a photo of it

you want more of this painting, so you decide to grab a random artist off the street and give them a vague (text) description of what the painting should look like and expect the random artist to be able to recreate

OK, I accepted that I was wrong with my goal, I expected somebody here knows or it's somewhere described - I mean all the hidden "cuisine" of the SD Online. This question is closed.

Just last one: When SD3 will be available for the Web-UI automatic update - is there somewhere any notes on this subject?

• Stable Diffusion 3 support #16030

• Stable Diffusion 3 support #16030

OK. Thank you for the info.
