Illustrious XL v1.0 – High-Resolution Focused Illustration Generative Model
Overview
Illustrious XL v1.0 is a cutting-edge generative model developed by OnomaAI, built upon the Stable Diffusion XL architecture. Trained from the previous checkpoint, Illustrious XL v0.1, this model is designed specifically to generate stunning, high-resolution images. It achieves an unprecedented native resolution of 1536×1536 within the SDXL framework, setting new standards for detail and clarity. The model integrates natural language understanding with Danbooru-style tag-based prompting, enabling flexible and robust prompt handling. Thus, Illustrious XL v1.0 serves as an ideal foundation for creators requiring versatility without sacrificing image fidelity.
Knowledge Cutoff
Illustrious XL v1.0 was trained in July 2024, with knowledge available up to June 2024. Thanks to native support of v0.1 LoRA, knowledge limits are largely mitigated.
Key Features
1536×1536 Native Resolution
- First-of-its-kind SDXL model supporting native 1536px resolution.
- Produces images with exceptional detail, sharpness, and clarity at high resolutions previously unattainable in SDXL.
- Capable of handling resolutions ranging from 512x512 up to 1536x1536, including non-standard resolutions like 1248x1824 without additional modifications.
NLP + Tag-Based Prompting
- Combines advanced natural language processing with concise Danbooru tag-based prompts.
- Users can employ plain English descriptions, precise tags, or both, providing greater control and nuanced image generation.
Extensive Compatibility
- Compatible with various extensions and add-ons.
- Supports seamless integration of LoRA, ControlNet modules, and other adaptation methods previously trained on Illustrious v0.1.
- Allows users to easily mix and match enhancements for style, pose, or composition.
Pretrained Base Model
- Provided as a pretrained base checkpoint without fine-tuning on specific aesthetics or biases.
- Ideal for creators seeking a flexible foundation to apply their fine-tuning, such as LoRA training, for specialized art styles or outputs.
Future Plans
Higher Resolutions in v3
- Upcoming releases (Illustrious XL v3) aim to support higher resolutions, targeting up to 2k resolution and beyond.
- Anticipate further enhancements in detail and scaling, enabling the generation of ultra-crisp, large-format images.
v-Parameterization Models & Color Control
- A specialized v-parameterization variant is in preparation, designed to push beyond SD XL's known limits academically and practically.
- Future updates will emphasize enhanced color control, offering precise adjustments for color balance and consistency.
Continuous Improvement
- The Illustrious roadmap commits to continuous integration of community feedback and incorporation of the latest research.
- Efforts in high-resolution research will persist, pushing boundaries with careful and innovative methods.
