First of all thank you for the tutorial. My shitty laptop took 6 hours and 30 minutes to generate a single image lol. I knew my computer wasn't going be fast but I expected it to take like 20 minutes or something.

Thanks for the tutorial, followed it step by step and managed to get good results even with a GTX1050. Obviously I can't do the complex workflows but I am getting very impressive results .

Stable Diffusion 3 models with names including "incl_clips" signify that these models have integrated text encoders. This integration means you do not need to add an extra node for those CLIP models, as the text encoding is already handled within the model itself. This differs from models like "sd3_medium, " where an additional node for the text encoders are necessary. So if you use sd3_medium.safetensor then add the clip encoders, for others are not need it from my understanding.

CivitAI just banned the SD3 because of the weirds license of stabilityAI, so play around with sd3 but because of the license many people will not be able to improve it or use it for comercial work.

Hi, do you think it's worth switching for now since it's just the beginning of SD3 or better wait for more commonity models developpeD?
Also I wasn't following what's happening with forge, will it stop to receive updates? I really like the ui similar to A1111 but better. Is is still worth sticking with one of the 2 for future SD3 version or it's time to learn Comfy? Ngl Swarm looks quite weird. Which one would you reccomend between all 4 from now on?

[makadi]

in 21:30 you changed the "sd3_medium" to "sd3_medium_include_clips" they are the same, just with the second one you can remove the TripleClipLoader node and pass the clip yellow line from the Load checkpoint node instead, the 6 gb model include two clips and the 15 gb one include all the 3 clips.

[Zaazu]

Will you be switching to another UI now that forge is changing to an experimental repo?

[andrewtran]

anyone else getting "Invalid operation: ComfyUI execution error: Cannot handle this data type: (1, 1, 3), <f4" when using Swarm, Windows, AMD?

[nomorejustice]

nice tutorial man, how to add the sdxl base model for swarmui?

[skystranger]

There are also versions for nvidia\amd gpus on huggingface, like Stable Diffusion 3 Medium TensorRT. Is it better to use them or this one ?

How much power does it use? Would we get slammed by the electric utility?

[mee_ehow]

So I have a pretty beefy PC sitting at home - RTX 4090 paired with 1/1gbps symetrical network connection. Is there a webserver version of that UI that lets me using this PC as raw horsepower for my webapps instead of paying third parties?

[shamilptashenchuk]

The model from old SD works in SD3? and Thnk for your video!

[spedroxsac]

[deejmag]
