What is mellow_pencil-XL_clear_v2?

mellow_pencil-XL_clear_v2 is a custom-tuned version of the anime model mellow_pencil-XL-v1.0.0-base, originally created by blue_pen5805.

Key Features of the mellow_pencil-XL Series:

  • Strong Detailing: Inherits high-quality detail from Illustrious-XL-v2.0.
  • Natural Language Support: Handles descriptive prompts very effectively.
  • Stylized Aesthetic: Produces cute, "deformed" anime-style illustrations.

I previously introduced the mellow_pencil-XL_clear_v1 model, but I’ve since applied further adjustments to pursue superior color expression. I’m happy to officially release and re-introduce mellow_pencil-XL_clear_v2.

Close-up View

Close-up comparison of skin texture. v2 on the left has uniform skin tones, while v1 on the right shows slight unevenness due to noise.
Left (v2): Less unevenness in skin tones

The previous mellow_pencil-XL_clear_v1 was a model specifically enhanced with intermediate noise to create a sharp, high-definition output.

While this increased contrast and detail, it sometimes resulted in a "burnt" color look or left behind color blotches/unevenness caused by noise artifacts.

In mellow_pencil-XL_clear_v2, I have slightly reduced the intermediate noise to achieve natural color expression and a cleaner texture. As a trade-off, the density of fine background details is slightly lower compared to v1.
