Magic Diffusion

A text2img model derived from StableDiffusion 1.5, fine-tuned with EveryDream-trainer on a dataset consisting of post-processed Magic the Gathering card art crops (32,159), and hi-resolution images of the art (13,048). Annotations are based on card metadata and various other sources, including art description.

Comparison

For MtG card art, this model performs comparably to Fantasy Card Diffusion v1. Both outperform generic models such as Open Journey v2, and baseline Stable Diffusion 1.5.

Conclusions:

Magic Diffusion v3 likes to draw borders and frames
Fantasy Card Diffusion v1 better preserves the MtG art style than Magic Diffusion v3, but it suffers from halftone/rosetta artifacts
OpenJourney v2 is much hornier than the rest of the models, but the results for generic concepts are comparable
Stable Diffusion v1.5 produces noticeably worse results than the other models, and requires a lot of negative keywords
All models seem to benefit from feature description, such as “sliver creature with long beak and tendrils” instead of just “sliver”

Presumably the results could be further improved with better prompts, targeted at specific models, but that is not the point of this comparison. Magic Diffusion does better without “artist signature”, Fantasy Card Diffusion may benefit from “halftone rosetta”, and Stable Diffusion 1.5 likes to draw the card frames.
