"Aira Lumina" is a huge additive model merge, as can be seen by its ~4gb fp16 size. It carefully combines well over 200 models, including both realistic and anime checkpoints.
This has been a labor of love, often doing and undoing merges based on the results. Probably the most impressive thing is the integrity of the results -- you have less control over whether you get anime/photorealistic photos, but it passes alexds9's overfit/corruption test with flying colors.
Because the merge is mostly additive, it performs well at both clipskip 1 and 2, and flipping back and forth can yield interesting results.
Enjoy!
