Recomendations:
Default SD 1.5: Use the "DPM++ SDE Karras" or "DPM++ 2M Karras"Β sampler with only 20 steps for better quality. "DPM++ SDE Karras" has better quality but is slow.
Default SD 1.5: Use the CFG scale between 5 and 9. CFG scale at 5 is recommended. Stable Diffusion default value is 7.
SD 1.5: Resolution between 512 and 768 using "Hires. Fix" or other form of upscaling. The 600x600 resolution is the one that has worked best.
SD 1.5 LCM: Use the "Euler a" or "LCM"Β sampler with only 8 steps for better quality.
SD 1.5 LCM AND SDXL Lightning: Use the CFG scale between 1 and 2. CFG scale at 2 is recommended.
Pony SDXL: Use the "Euler a" or "DPM++ SDE Karras" sampler with 20-30 steps for better quality.
Flux 1 Dev: Use the "Euler" sampler, "simple" scheduler, distilled cfg 3,5 and 20 steps.
If you use " Hires. Fix", use "Upscale by" with the value 1.5 with denoising at 0.6.
Tips for a better prompt:
Use (word) for larger weight and [word] for smaller weight and (word:0.5) to set the weight manually.
Recomendations for improvement on performance (Stable Diffusion Web UI):
Use Token Merging Ratio 0.5 on optimization settings.
If you have a GPU with low VRAM, use --medvram or --lowvram on command line arguments (webui-user.bat on Windows).
Enable fp8 in the latest versions of Web UI to save a lot of ram. It can speed up SDXL a lot depending on how much ram and vram you have.
If you are having a lot of trouble running SDXL in the Web UI. Try using Fooocus
Extensions I recommend: Controlnet, Booru tag autocompletion, CivitAI Browser+,Ultimate SD Upscale,Lobe Theme
Recommended negative prompts to improve human images: amputee, deformed body, long neck, extra fingers, bad body proportions, mutated hands, mutilated, mutation, ugly, fused fingers, malformed limbs, extra heads, disfigured,
