For example, <strong>Klein 4B </strong>and <strong>Klein 9B</strong> may still have severe anatomical issues. <a target="_blank" rel="ugc" href="https://civarchive.com/models/2324991/klein-anatomy-quality-fixer">In such cases, it may be useful to use third-party helper LoRAs.</a></p><h3 id="trigger">Trigger</h3><p><strong>No special trigger word </strong>is required for any of the versions.</p><p>The concepts should be invoked directly using their natural names.</p><h2 id="versions">Versions</h2><h3 id="krea-2-v2"><strong>Krea 2 V2 </strong></h3><p>V2 expands the dataset. The list of concepts has been expanded (see below), and stylized images were added during training for contrast. </p><h3 id="krea-2">Krea 2</h3><p>At the moment, this is the base model where the LoRA shows the most interesting behavior.</p><p>What I particularly like is how the understanding of individual concepts improves after enabling the LoRA: the model becomes noticeably better at distinguishing specific armor elements, weapons, and their construction.</p><p>Krea 2 also handles more complex and diverse prompts well, so this is where you can experiment with combinations of different historical concepts, artistic styles, and more complex scenes.</p><h3 id="klein-9b">Klein 9B</h3><p>For Klein 9B, I recommend generating at around <strong>8 steps</strong>.</p><p>Among the samplers, I particularly like <strong>res_multistep</strong>. In my experience, it helps reduce some of the model’s characteristic problems, especially situations involving multiple legs or strange variations of two-handed swords.</p><p>However, the LoRA itself does not eliminate Klein 9B’s fundamental anatomical problems. Its primary purpose is to improve the understanding and reproduction of the trained armor and weapon concepts.</p><h3 id="klein-4b">Klein 4B</h3><p>It is essentially the same situation as with Klein 9B, but the base model has more fundamental problems.</p><p>The LoRA improves the understanding of specific concepts, but it should not be expected to fix fundamental errors in the model itself.</p><p>The main advantage of this version is <strong>commercial-free use of the base model</strong>.</p><h3 id="anima">Anima</h3><p><strong>I did not like the result of training.</strong></p><h2 id="known-concepts-(main-list-for-all-versions)">Known Concepts (Main list for all versions)</h2><p>Below is a list of concepts that were sufficiently represented in the dataset and were considered trained.

It is specifically a <strong>concept helper</strong> designed to help the base model better understand the historical construction of armor and weapons.</p>
