<h3 id="i.-introduction">I. Introduction</h3>AnimaYume is a text-to-image model fine-tuned from <a target="_blank" rel="ugc" href="https://huggingface.co/circlestone-labs/Anima">Anima</a>, a high-quality anime-style image generation model developed by <a target="_blank" rel="ugc" href="https://huggingface.co/circlestone-labs">CircleStone Labs</a>. It builds upon<a target="_blank" rel="ugc" href="https://huggingface.co/Alpha-VLLM/Lumina-Image-2.0"> </a><a target="_blank" rel="ugc" href="https://research.nvidia.com/labs/dir/cosmos-predict2/">Cosmos 2</a>, a model developed by NVIDIA’s research team.<h3 id="ii.-information">II. Information</h3>For version 0.1:<ul><li>This model is a preview version fine-tuned from the Anima base model using a custom dataset. Training was conducted across multiple resolutions ranging from 768 to 1280 pixels, with a primary focus around 1024. The goal of this release is to improve stability and minimize unwanted artifacts when producing high-resolution images.</li><li>Notes: All the example images at this version were generated at the resolution 1024x1536 or 1536x1024</li></ul>For version 0.2:<ul><li>This model is a continuation of AnimeYume v0.1. In this version, I improved the quality of my dataset and used several techniques to prevent oversaturation and low-quality outputs. Based on my testing phase, I observed that the prompt coherence is better than v0.1, and the model remains very stable when generating images at a resolution of 1536.</li><li>Note: I am still waiting for the final version of Anima and testing some methods to make my training process faster. I know the license might make the model less popular, but I only care about whether the model is good or not. I’m aware that many others use better licenses, but I’m too lazy to spend a bunch of money training a model from scratch.</li></ul>For version 0.25:<ul><li>This version was trained on Anima Preview 2. Due to several issues with the base model, such as overfitting, black/white borders, quality inconsistencies, and problems with artist tags, I decided to focus primarily on improving the model’s knowledge, reducing these issues, and making it as stable as possible.</li><li>Note: In this version, I did not attempt to improve the model’s style. I tried doing so, but it caused the model to forget some of its existing knowledge. The training process is similar to v0.2, but the dataset has been adjusted to better address the issues present in Anima Preview 2.</li></ul>For version 0.3:<ul><li>This version was trained using Anima Preview 2. It is an experiment with a new training method for the model. You can consider it as another branch of AnimeYume 0.25, developed in parallel. However, this version uses new techniques and a larger dataset compared to v0.25.</li><li>Note: In this version, I experimented with a new training approach, so the model is slightly different from v0.25. Additionally, all example images were generated using prompts shared with users on CivitAI to evaluate whether this new method.</li></ul>For version 0.4:<ul><li>This version was trained on Anima Preview 3 using a custom dataset. In this release, I improved prompt understanding and artist style. Based on my testing, some artist styles match my expectations, although I haven’t tested everything in detail since I’m currently quite busy :&lt;. Additionally, I fixed several issues from Anima Preview 3 that also appeared in Preview 2.</li><li>Note: I’ve only tested with simple test cases, not comprehensively, so if you encounter any issues, feel free to let me know. I also used a larger AI computing cluster to speed up the training process :D.</li><li>All example images were generated using prompts shared by users on CivitAI, as I wanted to evaluate the model’s performance.</li></ul>For version 0.5:<ul><li>This version was trained on Anima Base v1.0 using my custom dataset (a mix of a small e621 dataset and Danbooru). In this release, I added many new characters and improved the existing ones. I also enhanced support for various artist styles, allowing the model to generate results that are much closer to the original styles. In addition, the model now understands some concepts and knowledge from e621, although the support is still limited.</li><li>Notes: I’ve only tested the model with a few simple test cases so far, so if you encounter any issues, feel free to let me know. This release can be considered a demo version showcasing my new training method, which focuses on preserving existing knowledge while adding new knowledge at the same time. The release also came sooner because I was finally able to use all the resources I had available :D</li><li>All example images were generated using prompts shared by users on CivitAI, as I wanted to evaluate the model’s performance using real user prompts.</li></ul>For version 1.0:<ul><li>This version was fine-tuned on Anima Base v1.0 using a variety of datasets, including Danbooru, e621, Gelbooru, and Konachan. The training approach differs from the original model in several ways. Most notably, I did not include quality score tags in the training data.</li><li>I also experimented with multiple captioning styles, ranging from traditional tag-based annotations to different forms of natural language descriptions, similar to the approach I used for Netayume Lumina.</li><li>Note:<ul><li>This release has two versions, each trained using different methods. For the v1.0 Demo, I experimented with a mixed training approach, but it was difficult to control. The v1.0 Final is different from the v1.0 Demo, so please don't compare them directly, even though they were trained on the same dataset. I created both versions to test different ideas for training diffusion models. Since Anima is small enough, it gives me the flexibility to experiment with various training methods and see what works best.</li><li>Unlike Netayume, I did not use my full dataset for training. (The complete dataset contains around 25 million images, and if I were to use the entire dataset, I would train a model from scratch rather than fine-tune an existing one.) Additionally, I have been quite busy recently, so I have not been able to test this model as extensively as I would like. Moreover, this model dont have any default style :L</li><li>V1.0 final has a watermark in the model, which is not effect the results of generated images. Moreover v1.0 currently support chain of though prompt as you can see in my example images i did it</li></ul></li><li>If you encounter any issues or have feedback, please feel free to share them with me.</li><li>All example images were generated using prompts provided by CivitAI users, as I wanted to evaluate the model's performance under real-world prompting conditions.</li></ul><h3 id="iii.-file-information">III.
