Description

Illustrious XL is an open-source, SDXL-based generative AI model from OnomaAI Research, optimized for native 1536x1536 anime-style illustration. It serves as an untuned base canvas — deliberately left without a fixed aesthetic — making it ideal for training custom checkpoints and LoRAs. The model features a Hybrid Prompting System that blends natural English sentences with comma-separated Danbooru2023 tags for precise control over characters, outfits, and scenes. It produces high-resolution images directly without relying on upscalers, supporting non-standard aspect ratios like 1248x1824. Powers thousands of derivative models and LoRAs on platforms like Civitai, with support for ComfyUI, Automatic1111, Forge, and Draw Things.
