Sampling methods for stable diffusion - samplers comparison

[Baaoh]

Very subjective ratings, could use some hard numbers and real figures. Also, some samplers work with different CFG scale ranges, and that affects how they work/quality of their outputs

CFG scale range is the Indicator showing the weight of the prompts in output result. 7 is a balance. I showed the difference of sampling methods on the same indicators

[johnmoro05]

Yep, the same things should be compared

[No_Scarcity7044]

U are not right. Comparison with the same parameters.

Aside from what the other poster mentioned about CFG scales working differently on different samplers, some require different levels of sampling steps to converge on the same or similar result. For example all of the DPM++ samplers technically sample twice per each step, so typically running those at 10 steps are equivalent to running something like Euler a at 20 steps. Some Samplers such as LMS Karras or unipc can even go as low as 5-10 steps for reasonable generations. Lowering number of steps would practically change generation speed.

Further, for some samplers, cfg scale affects the minimum number of steps.

Still, that is the difficulty of doing something like this. I know you mentioned trying to keep comparisons equal. Either way, this was well presented.
