Meina Mix

MeinaMix is a Stable Diffusion checkpoint model designed to generate high-quality anime-style artwork with minimal prompting requirements. Created by Meina, it exists within a broader family of models spanning versions V2 through V12, including specialized variants with and without VAE implementations and versions optimized for inpainting tasks.

Model Evolution and Capabilities

The latest iteration, V12, introduces several notable improvements over its predecessors, particularly in image brightness control and high-resolution generation capabilities. Special attention has been paid to enhancing eye detail rendering, while simultaneously reducing prompt bias and random variations in outputs. However, this increased consistency means that some previously effective short prompts may require additional detail to achieve desired results.

While the exact training methodology and data sources remain undisclosed, the creator has mentioned utilizing block weighted merges with various settings in the development process. This technique appears to contribute to the model's ability to generate consistent, high-quality outputs across a range of prompt types.

Optimal Usage Parameters

For optimal results, users should consider the following recommended parameters:

• Samplers:
  • DPM++ SDE Karras (20-30 steps)
  • DPM++ 2M Karras (20-60 steps)
  • Euler a (40-60 steps)
• CFG Scale: 4-9
• Resolution:
  • Portraits: 512x768 or 512x1024
  • Landscapes: 768x512, 1024x512, or 1536x512
• Clip Skip: 2

The implementation of hires.fix is strongly recommended, particularly when generating images with characters at a distance. The recommended configuration includes using R-ESRGAN 4x+Anime6b with 10 steps at 0.3-0.6 denoising. For optimal results with K samplers, quantization is advised.

Licensing and Community
