# Not-Illustrious XL v1.0 – High-Resolution Focused Illustration Generative Model



## Overview

**Not-Illustrious XL v1.0** is a cutting-edge generative model developed by **PetraAI**, built on the **Stable Diffusion XL** architecture. It is trained from our previous checkpoint, **Not-Illustrious XL v0.1**, and designed to produce stunning **high-resolution images**. 

It achieves an unprecedented **native resolution of 1536×1536** within the **SDXL** framework, pushing beyond previous limits in **detail and clarity**. The model seamlessly blends **natural language understanding** with **tag-based prompting** (Danbooru style), allowing both **descriptive sentences** and **specific tags** for **flexible and robust** prompt handling. 

As a result, **Not-Illustrious XL v1.0** is a powerful foundation for creators seeking **versatility in content generation without sacrificing fidelity**.

---

## Knowledge Cutoff

**Not-Illustrious XL v1.0** was trained in **July 2024**, with knowledge up to **June 2024**.

However, due to its **native support of v0.1 LoRA**, you might not have to worry about knowledge limits!

---

## Key Features

### 🚀 1536×1536 Native Resolution

- First-of-its-kind **Stable Diffusion XL** model to natively support **1536px resolution**.
- Generates images with **exceptional detail, sharpness, and clarity** at high resolutions that were previously unattainable in **SDXL**.
- Supports a **wide range of resolutions** between **512×512 to 1536×1536** – resolutions like **1248×1824** are possible without **high-resolution modifications**.

### 🧠 NLP + Tag-Based Prompting

- Integrates **advanced natural language processing** with **Danbooru tag-based prompts**.
- **Tag-based approaches** are more **concise and accurate**, but this hybrid prompt system means you can use:
  - **Plain English descriptions**  
  - **Precise tags**  
  - **Or both together**
- The model understands and **leverages each**, giving you **greater control** and **nuance** in image generation.

### 🔌 Extensive Compatibility

- Fully compatible with a wide range of **extensions and add-ons**.
- Supports **LoRA**, **ControlNet modules**, and other adaptation methods trained on **Not-Illustrious v0.1**.
- You can **mix and match enhancements** to fine-tune style, pose, or composition **without breaking compatibility**.

### 🏗️ Pretrained Base Model

- **Not-Illustrious XL v1.0** is provided as a **pretrained base checkpoint** without **fine-tuning** on specific aesthetics or biases.
- This **"raw" model** offers a **robust foundation** for further training.
- Ideal for creators who want to **apply their own fine-tuning** (e.g., **LoRA training**) to achieve **particular art styles** or **specialized outputs**.
- A **flexible starting point** for **new innovations**.

## Future Plans

### 🔍 Higher Resolutions in v2/v3

- Upcoming versions (**Not-Illustrious XL v2 and v3**) are planned to support even **larger resolutions**, targeting up to **2K resolution and beyond**.
- Expect **even more detail** and **scaling capability**, enabling **ultra-crisp large-format images**.

### 🎨 v-Parameterization Models & Color Control

- A specialized **v-parameterization variant** is ready, **breaking SDXL's previously considered limits** – both academically and practically.
- Future releases will focus on **enhanced color control**, allowing users **finer adjustments** over **color balance** and **consistency** in generated images.

### 🔄 Continuous Improvement

- The **Not-Illustrious roadmap** is ambitious – each iteration will integrate **community feedback** and the **latest research**.
- We will continue **high-resolution research**, breaking previously considered limits with **careful and sophisticated approaches**.
