Because of the dataset is not small, the model is not overfitted. It does not drastically change the content. But it does can drastically change the details.For example: (image is compressed, see original image <a target="_blank" rel="ugc" href="https://civarchive.com/images/104848740">here</a>.)<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/71ebdb46-82b4-4429-8767-eddb6922a58a/original=true,quality=90,optimized=true/104848740.jpeg" /><hr /><h3 id="how-to-use">How to use</h3>Strength 1 is recommended.For anime, start with "Digital anime illustration." as trigger words.Recommended settings: I use euler_cfg_pp with cfg 0.5~0.7, beta schedular, 30 steps.For Civitai online generator, use cfg 3, 30~40 steps.<hr /><h3 id="license">License </h3>This model is released under Apache License 2.0.Additional terms: Selling or monetizing models that merged this LoRA is prohibited.<hr /><h3 id="update-logs">Update logs</h3><ul><li>(10/4/2025) v0.1 init release.</li></ul><hr />You have read this far, don't forget to leave a feedback in discussion.

<h1 id="enhancement-bundle-for-chroma-hd">Enhancement bundle for Chroma HD</h1>Cover images are raw output from the model, 1MP resolution, no upscale, no hands/faces inpainting fixes, even no negative prompt. They are not perfect, but 100% "what you see is what you get".<hr /><h3 id="this-model">This model</h3>This is an all-in-one (all aspects I can come up with) finetuned model.Trained with total ~5k images. Mainly photograph and some anime images.<ul><li>No AI images. Not on my watch. Every image is hand-picked by me. Only high resolution images with finest details. The whole dataset avg pixels is 3.37 MP, ~1800x1800.</li><li>Comprehensive natural language captions from Google LLM.</li><li>Anime characters are tagged by wd tagger v3 first and then refined to natural language by Google LLM.</li></ul>EffectsFor general realistic image:<ul><li>It gives you better natural texture and details.</li><li>Better lighting, a little bit cinematic feelings.</li><li>Less overexposure and oversaturation.</li></ul>For anime:<ul><li>Because Chroma does not support artist tags, and quality tags (not sure though, in my tests, the base model didn't response to those tags.). It's very unstable for anime.</li><li>I added a default anime style. This default anime style is mainly for reducing noise and overfitted bias that towards simple low quality image.</li><li>Also included a sub dataset full of hands.</li></ul>Why a bundle, rather separated LoRAs for different aspects?This a mathematic problem. You can ask an AI for a quick answer. "When using an image model, what's the problem if I stacked too many LoRAs on my image model? In mathematic aspect."If you train all your data and concepts in one go, then there will be no conflicts.<h3 id="how-to-use">How to use</h3>Simple, this is a LoRA, apply it with strength 1 then you will get the finetuned model.For anime, use "Digital anime illustration of ..." as trigger words.Recommended settings: I use euler_cfg_pp with cfg 0.5~0.7, beta schedular, 30 steps.<hr /><h3 id="license">License </h3>This model is released under Apache License 2.0.Additional terms: Selling or monetizing models that merged this LoRA is prohibited.<hr /><h3 id="update-logs">Update logs</h3><ul><li>(10/4/2025) v0.1 init release.</li></ul><hr />You have read this far, don't forget to leave a feedback in discussion.
