Despite being a continuation, the model was retrained from <a target="_blank" rel="ugc" href="https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0">Stable Diffusion XL 1.0</a> with a massive dataset of 8.4M diverse anime-style images from various sources with the knowledge cut-off of January 7th 2025 and finetuned for approximately 2650 GPU hours. Similar to the previous version, this model was trained using tag ordering method for the identity and style training.With the release of Animagine XL 4.0 Opt (Optimized), the model has been further refined with an additional dataset, improving stability, anatomy accuracy, noise reduction, color saturation, and overall color accuracy. These enhancements make Animagine XL 4.0 Opt more consistent and visually appealing while maintaining the signature quality of the series.<h2 id="changelog-gqeo5zabv">Changelog</h2>- 2025-02-13 – Added Animagine XL 4.0 Opt and Animagine XL 4.0 Zero<ul><li>Better stability for more consistent outputs</li><li>Enhanced anatomy with more accurate proportions</li><li>Reduced noise and artifacts in generations</li><li>Fixed low saturation issues, resulting in richer colors</li><li>Improved color accuracy for more visually appealing results</li></ul>- 2025-01-24 – Initial release<h2 id="model-details-ldqhi7qps">Model Details</h2><ul><li>Developed by: <a target="_blank" rel="ugc" href="https://github.com/cagliostrolab">Cagliostro Research Lab</a></li><li>Model type: Diffusion-based text-to-image generative model</li><li>License: <a target="_blank" rel="ugc" href="https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/blob/main/LICENSE.md">CreativeML Open RAIL++-M</a></li><li>Model Description: This is a model that can be used to generate and modify specifically anime-themed images based on text prompt</li><li>Fine-tuned from: <a target="_blank" rel="ugc" href="https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0">Stable Diffusion XL 1.0</a></li></ul><h2 id="usage-guidelines-oepvp8jeo">Usage Guidelines</h2>The summary can be seen in the image for the prompt guideline.<img src="https://cdn-uploads.huggingface.co/production/uploads/64c088660a4d02f37a965f6c/YPe3MCnQAHM7nCZ1vQ7vI.png" /><h3 id="1.-prompt-structure-s2bolxh5w">1.

These tags are carefully weighted and tested to provide consistent results across different prompts.<h3 id="quality-tags-6f9nx9zlc">Quality Tags</h3>Quality tags are fundamental controls that directly influence the overall image quality and detail level. Available quality tags:<ul><li><code>masterpiece</code></li><li><code>best quality</code></li><li><code>low quality</code></li><li><code>worst quality</code></li></ul>Score TagsScore tags provide a more nuanced control over image quality compared to basic quality tags. They have a stronger impact on steering output quality in this model. Available score tags:<ul><li><code>high score</code></li><li><code>great score</code></li><li><code>good score</code></li><li><code>average score</code></li><li><code>bad score</code></li><li><code>low score</code></li></ul><h3 id="temporal-tags-8eivwxggr">Temporal Tags</h3>Temporal tags allow you to influence the artistic style based on specific time periods or years. This can be useful for generating images with era-specific artistic characteristics. Supported year tags:<ul><li><code>year 2005</code></li><li><code>year {n}</code></li><li><code>year 2025</code></li></ul><h3 id="rating-tags-qjdv8wcse">Rating Tags</h3>Rating tags help control the content safety level of generated images.

Unfortunately, this forced us to refund all donations and left us without a reliable way to receive support. To avoid such issues and ensure transparency, we have now switched to cryptocurrency as the way to raise the fund. Want to Donate in Non-Crypto Currency?
