<h3 id="latent-chimera-is-an-illustrious-based-model-with-an-emphasis-on-semi-realism.">Latent Chimera is an Illustrious based model with an emphasis on semi-realism.</h3>Switching to Forge improved memory management significantly, making SDXL models more practical. After exploring various models, I decided to merge my favorites to experiment with new possibilities. Latent Chimera has non-Illustrious SDXL models mixed back in to boost creativity and reduce overfitting.This model is the result of combining multiple sources using the <a target="_blank" rel="ugc" href="https://github.com/hako-mikan/sd-webui-supermerger">SuperMerger </a>extension for A1111. Through methods such as MBW, cosine interpolation, and static weight blending, I aimed to produce a composition distinct enough to warrant sharing—an outcome shaped by ongoing experimentation with merge strategies.All source model licenses were reviewed prior to merging, and the most permissive terms available under the inherited usage conditions were applied. Merge recipes are included in metadata. VAE has been baked in.<h3 id="reality-check">Reality Check</h3>This isn’t intended as a flagship model. My aim here isn’t to drop a “top-tier” release, but to explore merge behavior, stylistic bias, and scene composition in a controlled way. I avoid rushing merges right after donor model releases, both out of respect for the creators and to keep the focus on understanding mechanics—not chasing hype. Most of my excessively long prompts are reused across tests so I can compare bias and behavior between models; while I still make occasional adjustments, I generally post results as they come—flaws, quirks, and all.
