Use the "DPM++ SDE Karras" or "DPM++ 2M Karras" sampler with only 20 steps for better quality. "DPM++ SDE Karras" has better quality but is twice as slow.
Use the CFG scale between 5 and 9. CFG scale at 5 is recommended. Stable Diffusion default value is 7.
Resolution between 512 and 768 using "Hires. Fix" or other form of upscaling.
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:
Use Token Merging Ratio 0.5 on optimization settings.
If you have a GPU with low VRAM, use --medvram on command line arguments (webui-user.bat on Windows).
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,
I would like to thank the following projects that were important to the community and helped improve Stable Diffusion to achieve greater levels of realism:
This model is capable of generating very realistic images that can confuse people's critical sense, please do not use it irresponsibly, harming ordinary people or public figures. Although the field of artificial intelligence is poorly regulated, its improper use can cause legal penalties even in countries with little regulation in the area. Be very careful to not commit crimes in your country and not to promote injustices against innocent people.
