Welcome to OS Models!
This is my second true checkpoint merge, and the goal is simple — pure 2D cel-shaded anime with MUSCLES. This checkpoint is built from the ground up with one vision in mind: that clean, crisp, authentic anime screencap look you'd pull straight from your favorite animated series. Sharp linework, bold flat cel shading, punchy colors, and that unmistakable hand-drawn 2D feel that makes anime so iconic.
It handles a wide range of anime aesthetics too — bold shonen energy, clean slice-of-life warmth, sharp seinen contrast, and more — all while keeping that flat, 2D cel-shaded core. LoRA compatibility has been strong in testing, so your favorite style and character packs should slot right in.
This is my first release after a lot of testing and refinement, so please give it a go! Drop your results, questions, and suggestions in the comments — I'd love to see what you create. Donations to Yellow Buzz are hugely appreciated and go straight back into building more LoRAs and checkpoints for everyone to enjoy!
