description: <h1><strong>v2.0</strong></h1><p>A LoRA of the Hisakawa twins from THE iDOLM@STER Cinderella Girls based on 967 fanarts. More style neutral than v1.1.</p><p>Two versions are available: rank 1 and rank 4.</p><p>This shows that, perhaps unsurprisingly, 1 rank can carry info of more than 1 character.</p><p>Despite the abundance of two-subject data in the training set, the model still struggles to separate the attributes of the twins in the image. Increasing the model rank may or may not help. This will be investigated some time in the future.</p><h2>Usage</h2><p>The character tags are <code>Hisakawa Nagi</code> and <code>Hisakawa Hayate</code>.</p><p>To generate both characters in the same image, use either <code>Hisakawa Nagi / Hisakawa Hayate</code> or <code>Hisakawa Hayate / Hisakawa Nagi</code></p><p>Top related tags:</p><pre><code>Hiwakawa Nagi,
