How to prevent multiple images of the character?

Tried searching Google, but couldn't find anything, probably because I'm asking it wrong. Most posts were asking how to create multiplies. In my case, I just want one character.

I'm new to Stable Diffusion and tried using the following parameters:

prompt: Hatsune Miku, 4k, 8k, 16k
negative: lowres, bad anatomy, bad hands, text, error, missing fingers, extra digit, fewer digits, cropped, worst quality, low quality, normal quality, jpeg artifacts, signature, watermark, username, blurry, artist name

seed: -1
steps: 40
sampling: euluar a
size: 768x768

It generated an image with two overlapping Mikus. If I increase the size of the image, it creates even more overlapping Mikus.

Do I need to be more specific with my prompts or something?

Your prompt is too simple, you could specify "alone, solo, picture, etc". You could also decrease the width ( more you move away from 512px, the more likely are these duplicates), use highresfix, for high resolutions. We also don't know how much you tried, maybe you did just that one image and it just looked like that, but if you did another 50, it didn't happen.

Okay thanks. Yeah, sorry I did not mention that I ran it four times and the result was the same, just a different scene.

I'll add more prompts as suggested.

The old way to fix this when you were generating over 512x512 was to specify more than the main subject i.e the background ironically words like "alone, solo, etc" will more than likely give you duplicate characters since the generation will try to fill empty spaces with your prompt and alone solo imply a character in that space so in the past things like "grassy field, sky, city street" would be what you would do so that the empty spaces are filled with non-character objects

Anyway if you want to do this now however that's not necessary anymore as most models are trained on larger more varied resolutions if your having this problem you can try here downloading an anime model from https://civitai.com/ most anime the models there should be alot better

In negative prompt I put "duplicate characters". It s work for me for 1024x1024. But I guess it work for some model.
