I clocked 18 seconds for a 512*512 image, 25 steps, on a Mac Studio with M1 Max and 32GB.
FWIW I don't I've ever gotten a satisfactory result from anything less than 50 steps
Interesting. I didn’t see an essential difference with higher values, so I settled on 25. Maybe I’m just impatient and my brain prefers more options even if they’re individually imperfect.
Depends on the diffuser you're using, the _a (ancestral) diffusers are aberrant in that they can yield good results with very low sample counts. I typically use 16 samples and get reasonably good results, but it's highly dependent on the prompt and settings as well.
On Replicate it takes maybe around 10-15 seconds. My M1 Pro only has 16GB and 8 cores and takes about 1 minute, so maybe the lower specs make quite a difference.
You should be able to get a regular prompt to generate in 5 seconds via https://mage.space. A100s under the hood. Unlimited too. (Note: I am the creator)
8 seconds here, awesome!
Wow! What's your motivation to provide access to such powerful hardware for free?
