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!

Sampler & Scheduler Suggestions:

1. Euler Ancestral + Normal/SGM Uniform — 30 steps @ 4.5 CFG

2. DPM++2M + Karras — 30 steps @ 4.5 CFG

This checkpoint includes a built-in VAE and supports hi-res fix.

Hi-Res Suggestion: Euler or DPM++2M — 12–15 steps @ 0.35 denoise (1.5× or 2×)
