For best outputs:

Sampler: DPM++ SDE

Steps: 50, cfg 7.5, CLIP skip 1

VAE: none required.

Pos prompt: from simple prompts to weighted keywords (not too much tho), just ask and the model will give. This is a versatile type of model, it can go from a pretty decent photorealism to a more than acceptable cute anime. Just play with both prompts, placing in each one the style and its anti-style. For example, to get anime, in the pos: "(Anime style, japanese animation style, Ghibli influence, cartoon, 2d, flat 2d style)".

Neg prompt: as explained above, in here it goes the "anti-style", for example, to create anime, in the neg: "volumetric, cinematic, photorealistic, realistic, deformed, glitch, noisy, low contrast, porcelain hair, long neck, asymmetrical eyes, black background, signature, watermark".
