I made a new worklow for HiDream, and with this one I am getting incredible results. Even better than with Flux!
It's a txt2img workflow, with hires-fix, detail-daemon and Ultimate SD-Upscaler.
HiDream is very demending, so you may need a very good GPU to run this workflow. I am testing it on a L40s (on MimicPC), as it would never run
on my 16Gb Vram card. Also, it takes quite a bit to generate a single image (mostly because the upscaler), but the details are incredible and the images are much more realistic than Flux (no plastic skin, no flux-chin).
If you use HiDream Full model I suggest you to use the Ultra-Pro (L40S) hardware. HiDream Full is the only version that can use Negative Prompt (so you can even set the CFG).
Schedulers suggested :
normal, sgm_uniform, simple, beta (these three have similar results), linear_quadratic and ddim_uniform
Samplers that work :
euler, euler_ancestral, heun, heunpp2, dpm_2, dpm_2_ancestral, lms, dpm_adaptive, dpm_2s_ancestral, dpmpp_2m, lcm (not for realism), ipndm, ipndm_v, deis, res_multistep, gradient_estimation, er_sde
