Adonis for Flux 2 Klein 9B (Workflow)

Adonis is an "upscale model" LoKr trained using a high-resolution "target" dataset of men, paired with synthetic low-resolution edited copies as the "control." It refines skin, hair, and anatomy details that base model often gets wrong.

How it Works

• Edit-Only: Improves only what is already visible in the input image. Suitable for any image involving people.

• Two-Model Generation: The model splits into two models (adonis_base and adonis_refine) that work best together:

  1. Adonis Base: Sets the image structure and color first. (first 4-6 steps)

  2. Adonis Refine: Brings out details and corrects issues from the initial steps. (final steps, 9 steps total)

Recommended Prompt

This prompt enhances most images effectively:

uhdmanscale, fully reconstruct this entire image from cellphone quality to professional high resolution color raw quality. Remove halftone dot pattern. Apply descreen filter. Eliminate periodic grid noise. Eliminate repeating noise patterns and artifacts, remove uniform diagonal line texture patterns. Reconstruct low resolution high ISO noise areas with high resolution low ISO noise textures.

Apply full detail reconstruction to all areas: background, environment, surfaces, objects, clothing, and foreground elements — render everything sharp, textured, and high fidelity.

Subject identity is locked: preserve exact facial geometry and body geometry, eye shape and color, nose and mouth shape, and expression. On skin areas, remove color blotch artifacts, normalize tone uniformity, preserve natural pore and texture detail. On hair and body hair areas, separate smeared color artifacts, restore strand separation and texture. Outside the subject's face, freely reconstruct all texture and sharpness with no restrictions.

Deblur and focus correction pass. Infer and reconstruct underlying detail from soft source: sharpen edge definition, recover eye detail, lip definition, and skin texture from motion blur. Output as professional high resolution color camera RAW image.

Note: For non-color inputs, specify object colors in the background. Replace "color" with "black and white" if you do not want to colorize the image.

Model Files & Requirements

Base Models:

• FLUX.2-klein-9B.safetensors (HuggingFace: black-forest-labs/FLUX.2-klein-9B)

• Flux 2 VAE (HuggingFace: Comfy-Org/flux2-dev)

Clip:

• Qwen3-8B-GGUF

  • Use a higher quantization GGUF if VRAM is limited. FP8 tends to degrade details in eyes and fingers based on testing.
