<h2 id="krea-2-anime-tuned">Krea 2 Anime-tuned</h2>An anime full fine-tune of Krea 2 (all 12.8B DiT parameters) on ~196k curated anime illustrations. This page has two versions that work best together:<ul><li>Turbo: Krea 2 Turbo plus the full weight delta of the Raw fine-tune. Use it alone with 8 steps and no CFG.</li><li>Raw: the fine-tuned Krea 2 Raw (EMA weights). Use it alone with CFG at ~1 MP, as the first stage of the hybrid sampler, or as a base for LoRAs.</li></ul>Recommended: the hybrid sampler. Raw generates the first 2 of 8 steps with CFG, then Turbo finishes the last 6 without CFG. All sample images were made this way at 2K.<h3 id="files-(comfyui)">Files (ComfyUI)</h3><ul><li>This model (<code>fp8_scaled</code>, 13.1 GB per version) → <code>models/diffusion_models/</code>.

Short tag lists work, but prompts in this style work best.capgen turns a few Danbooru tags into a full caption in this style. It needs no LLM, runs on CPU, and takes milliseconds per caption. Ways to use it:<ul><li><a target="_blank" rel="ugc" href="https://github.com/ricecake000/ComfyUI-Krea2-Anime-Capgen">ComfyUI custom node</a> with tag autocomplete. Search "capgen" in ComfyUI-Manager.

To exclude something, add <code>-tag</code>, e.g. <code>1girl, -white background, -cleavage</code>. The sample images used this.The samples were rendered on the author's TPU serving stack with the hybrid sampler, so the same prompt and seed will not give identical pixels in ComfyUI.<h3 id="training">Training</h3><ul><li>Data: 196,099 anime illustrations from Danbooru and Gelbooru. Only <code>general</code> and <code>sensitive</code> ratings, at least 1 MP, at least one girl, no male focus, and watermarked or text-heavy images removed.

Krea 2 Anime-tuned

Raw: the fine-tuned Krea 2 Raw, using the EMA weights from the final training step. On its own, use 28 steps and cfg 5.5 around 1 MP. In the recommended hybrid sampler it runs the first 2 of 8 steps. It also works as a base model for further training and LoRAs.The sample images are hybrid renders: this version for steps 0-2, then the Turbo version for steps 2-8. They are the same images as on the Turbo version and are not Raw-only outputs.
