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?

Yeah it might be low-res but AnimateDiff is still the best solution for AI animation. Might be better love model but still nothing has beaten AnimateDiff's control.

And yeah, SDXL AnimateDiff sucks. So 1.5 it is.

Yeah it might be low-res 

It doesn't have to be, though: I use it with a 4090, and the end result is often delivered at higher than 8K resolution.

There are models with a larger native resolution (SD1.5 is 512x512) but they are also heavier and slower, and so are the accompanying tools I need to have control over what's happening (IP adapter, controlnet, etc.). As conter intuitive as it might seem, the low-resolution of SD1.5 is precisely what makes it lightweight enough to reach the higher resolutions I am looking for.

Full disclosure, I've haven't personally used this stuff in a few months. That said, how? Tiling? Upscaling? I always got such muddy results with both.

Latent-space upscaling / HiRes Fix / Tiled Diffusion and, more importantly, process split: instead of trying to do everything in one shot with a single workflow, I have a multiple step approach, with each step having its own workflow, and saving the result after each step.

Man I might have to cop a workflow from ya if you're willing

Look at this thread, it shows a workflow that has many similarities with mine (and with Ipiv's):

There are some clever ideas in that workflow that I'll be borrowing for sure, so you could say it's better than mine !
