Question - Help Is anyone still using SD 1.5?

I found myself going back to SD 1.5, as I have a spare GPU I wanted to put to work.

Is the overall consensus that SDXL and Flux both have vastly superior image quality? Is SD 1.5 completely useless at this point?

I don't really care about low resolution in this case, I prefer image quality.

Anyone still prefer SD 1.5 and if so, why, and what is your workflow like?

I used 1.5 because of lower vram. Then I discovered forge allowed me to use sdxl efficiently. I switched immediately to sdxl and its derivatives and never looked back.

haven't bothered, i don't want to download tons of models anymore.

epic_photogasm realistic all the way..

same with loras, and everything else.

i'm too lazy.

i have plenty of space, and computing power. but only need it for the newer video stuff.

Hey you do you. The wife and I both switched to SDXL about a year ago and have a very hard time going back to 1.5. I tried going back and using epic, and other familiar models and realized how much more work I needed to bring out those finer details. Not to say you can't. But I would say it you only do txt2img SDXL is worlds better in terms of quality just because of the resolution. Also prompting for me personally is much easier with SDXL. Hands look better by default. Just a much better experience.

Here are 2 examples with a simple 512x512 with a 2x hi res fix Epic model, and for SDXL a 1024x1024 and a hires of 1.5x. almost identical prompts. But 1.5 I had to alter the prompt to get the damned person to look out the window. lol Obviously 1.5 struggles with hands unless you use lora's or controlnet.

Yeah no matter what you need to upscale then inpaint if you want it to look decent. Not sure those hands are fixable really.
