<h1 id="heading-57">这破COS模型谁爱炼谁炼吧，我再炼就是傻逼，这傻逼高P图炼丹本身就是无稽之谈</h1><h1 id="heading-7">还有，这模型训练量严重不够，有训练更多的在Q群发过，也烂的要死，有时间整个踩坑记录</h1>Thank <a target="_blank" rel="ugc" href="https://civarchive.com/models/296650/rumblexl-animagine-based-photographic-model">RumbleXL</a> for helping me verify the feasibility of doing so.This model is specifically used to generate Cos graphs.Since it is trained from the animation base model, the body and hand effects of generating images are relatively poor. If you want a better effect, you can try MBW processing.I also tried to use a real human model to train, but the hair will always be black, can not achieve the desired effect, so give up, can only use anime base model training.<h2 id="heading-215">Train</h2>CosXL is trained using 6000 high quality cos diagrams, using Lokr training with the base model AnimagineV3, the difference between A and B is that they use different LBW.<h3 id="heading-9">dataset</h3>The training dataset used consists of over 6000 randomly selected images from Cosbooru, sourced from an adult cosplay website. Among the selected 6000+ images, 95% of them feature cosers from East Asia. The training images utilized are a collection of images after excluding NSFW content.<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/79040a5b-bb3d-42f7-81dc-626436908cdf/width=525/79040a5b-bb3d-42f7-81dc-626436908cdf.jpeg" /><img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/7890921d-0eb1-4326-8040-bd2daf7f94b0/width=525/7890921d-0eb1-4326-8040-bd2daf7f94b0.jpeg" />Training dependent parameter:<pre><code>Cosplay Model XL
