Stable Diffusion: samplers comparison
I ran the same prompt using many samplers at different steps counts to evaluate which one(s) give a decent quality at a low step count. I have not used the “restore faces” option. Here are my observations related to image quality (artifacts) and convergence. Quality at lower steps At 10 steps, a few samplers are unusable: DPM++ 2M and its variants, DDIM. At 15 steps, all samplers are OK except DPM++ 2M SDE and its Karras variant are unusable....
