The Z-image version is trained using the BF16 version of Z-image base. The Krea 2 version is trained on K2 Raw. The dataset consist of 60 Midjourney Niji images created by my friend Stan Katayama (creator of SDXL Niji, one of my favorite models): https://civarchive.com/models/120765/sdxlnijispecial-edition

Z-image base is already quite capable at producing anime images, this LoRA simply aligns the model closer to the "Niji look", specifically Stan's take on the Niji style. It can be combined nicely with other styles that are already "built-in" into the base, such as "Story book", "Studio Ghibli", "Vintage anime", "Pop-art", etc. to make anime images with a variety of styles.
