Note that this version may reduce the quality of image generation across multiple art styles.</li><li>For version 3.0: This version can generate images in multiple styles (similar to version 1.0) while also creating more realistic characters (more lifelike compared to version 2.0) with improved anatomy. However, to achieve the desired image, you need to input a precise descriptive prompt, as it significantly impacts the output.</li><li>In version 4.0, to adapt to the large amount of data used for training, I reconstructed the model with some modifications. Moreover, I had to train all parts of the model, including CLIP, VAE, and UNet. In this version, the improvements allow the model to generate image styles more accurately, as well as improve the character anatomy. In addition, I fixed the issues that occurred in versions 2.0 and 3.0.</li></ul><h2 id="important-note-et74bkod1">Important Note</h2><ul><li>I personally reconstructed this model, so I’d greatly appreciate any feedback.
