**Overview** **Animagine XL 4.0**, also stylized as **Anim4gine**, is the ultimate anime-themed finetuned SDXL model and the latest installment in the **Animagine XL** series. Despite being a continuation, the model was retrained from **Stable Diffusion XL 1.0** using a massive dataset of 8.4 million diverse anime-style images from various sources, with a knowledge cut-off of **January 7, 2025**, and fine-tuned for approximately **2,650 GPU hours**. Like its predecessor, this model was trained using the tag ordering method for identity and style consistency. With the release of **Animagine XL 4.0 Opt** (Optimized), the model has been further refined with an additional dataset, enhancing its performance for general use. This update brings several improvements: - Better stability for more consistent outputs - Enhanced anatomy with more accurate proportions - Reduced noise and artifacts in generations - Fixed low saturation issues, resulting in richer colors - Improved color accuracy for more visually appealing results This optimized version ensures higher-quality outputs while maintaining the signature style and flexibility of the **Animagine XL** series.
