<h2 id="arknights:-endfield-or-operators-collection">Arknights: Endfield | Operators Collection</h2>Intended to generate non-commercial fan works of Operators from the Arknights: Endfield video game.ℹ️ LoRA work best when applied to the base models on which they are trained. Please read the About This Version on the appropriate base models and workflow/training information.Version 3.0 (Latest)This was re-trained with several attempts to reach the same level of quality as the full-finetune which included the same dataset:<a target="_blank" rel="ugc" href="https://civarchive.com/posts/29295260/edit?modelId=2495369&amp;modelVersionId=3020412">Kirazuri (Anima)</a>The LoRA is not quite there, even when adjusting hyperparameters and extending the training time.Little disappointed about this, but it may be an expected limitation of LoRA training.Operators (game version 1.0):<pre><code>
