This is a LoRa I decided to train on gpt-img-2. There's two goals: improve facial texture and increase body proportions. Ideogram by default can't move away from a slim body. This pushes it to be nearly as good as the 200 elo better gpt-img. It happened to be mainly Korean, I generated most of the images before Ideogram was even released.<h2 id="trigger">Trigger</h2>Use:<code>Korean</code>Place it once near the start of the woman’s description:<code>Korean, woman with...</code>Because <code>Korean</code> is also a normal word understood by the base model, it may affect facial appearance and styling as well as the trained body shape.

Korean Body enhancer | Ideogram

Initial release. First training run. Great results but the dataset wasn't generated intending to train a model.
