Boogu-Image-0.1 is a research project only, and not an official model release.

📖 Introduction

Boogu-Image-0.1 is a competitive Apache-2.0 open-source unified image generation and editing model family, including Base, Turbo, Edit, and Edit-Turbo, and other variants that provide stable, practical capabilities for high-quality text-to-image generation, fast generation, image editing, and Chinese-English text rendering. Closed-source multimodal understanding and generation systems like Nano Banana Pro and GPT-Image-2 achieve remarkable performance not because of a single model, but through a highly unified suite of system capabilities. However, under training compute that is extremely limited compared with closed-source systems, we find that systematically improving a model's understanding ability, data quality, and training pipeline can still significantly improve image generation and editing performance. Specifically, compared with some existing open-source models, our training data scale is roughly one order of magnitude smaller. We hope our empirical study and open-source release will help advance the open-source ecosystem for multimodal generation and understanding.

This repository provides checkpoints and inference code for Boogu-Image-0.1.

🏆 Boogu Arena

Since we could not evaluate on LM Arena directly, we built Boogu Arena, an LM Arena-style preference evaluation. We use an LLM to generate diverse user personas, then ask each persona to produce image generation prompts, resulting in 1K+ test prompts that we will release publicly for community reproduction. The ELO leaderboard below spans leading closed- and open-source systems. We welcome teams with questions about the results to contact us so that we can work toward a more objective, fair, and reproducible evaluation.

🔬 Scenario-wise Comparison

Beyond overall arena rankings, we break performance down by scenario across leading open-source peers. Ratings reflect our internal evaluation of typical prompts in each category.

• 📸 Photography with reliable text rendering — Boogu-Image-0.1-Turbo delivers realistic photography, while also offering solid performance on both simple and dense text rendering.
• 📝 Strong dense text rendering — Boogu-Image-0.1-Base shows competitive results on dense, layout-heavy text scenarios such as posters, documents, brand guides, and complex bilingual designs.
• 💡 Recommendation — When your workload is dominated by dense / ultra-dense text rendering needs, we recommend running Boogu-Image-0.1-Base at 2K output resolution for the best layout fidelity and character accuracy.

📥 Model Zoo

• Boogu-Image-0.1-Base: Foundation model with strong diversity and controllability — ideal for fine-tuning and downstream development. Mainly intended for ultra-dense text rendering; for photorealism, Turbo is usually the better default. Supported resolutions: 1K, 1.5K, 2K.
• Boogu-Image-0.1-Edit: Image editing and transformation variant. Supported resolutions: 1K, 1.5K, 2K.

• Boogu-Image-0.1-Edit-Turbo: Distilled variant with the same parameter count.

Unless otherwise specified, all model variants support the following aspect ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 1:2, 2:1, 9:16, and 16:9.

🛠️ Installation

Tested environment: Python 3.10 · CUDA 12.6 · PyTorch 2.7.1

# Use a brand new conda environment
conda create -y -n boogu python=3.10
conda activate boogu
# Instal necessary dependencies
# PyTorch up to 2.11.0 with CUDA up to 12.8 is supported
# Check `requirements/<torch>_<cuda>.txt`
pip install -r requirements/torch2.7-cu126.txt
pip install -e .
python utils/get_flash_attn.py

or

bash quick_start.sh
conda activate boogu

Download Checkpoints

Download the model weights into a local models/ directory before running inference. We recommend using the official Hugging Face CLI:

pip install -U "huggingface_hub[cli]"

# Download to ./models/<model-name>
huggingface-cli download Boogu/Boogu-Image-0.1-Base --local-dir models/Boogu-Image-0.1-Base
huggingface-cli download Boogu/Boogu-Image-0.1-Turbo --local-dir models/Boogu-Image-0.1-Turbo
huggingface-cli download Boogu/Boogu-Image-0.1-Edit --local-dir models/Boogu-Image-0.1-Edit
huggingface-cli download Boogu/Boogu-Image-0.1-Edit-Turbo --local-dir models/Boogu-Image-0.1-Edit-Turbo

Example layout after download:

models/
└── Boogu-Image-0.1-Base/
    ├── model_index.json
    ├── mllm
    ├── processor
    ├── scheduler
    ├── transformer
    └── vae

Then point inference to the local path via --model models/Boogu-Image-0.1-Base.

Flash Attention

This repository provides utils/get_flash_attn.py to automatically install a compatible flash-attn wheel for your environment.

Requirements:

• Python and PyTorch with CUDA already installed
• Linux x86_64

# Auto: detect environment, download a prebuilt wheel, fallback to source build
python utils/get_flash_attn.py

# Force source compilation
python utils/get_flash_attn.py --build

The script first searches mjun0812/flash-attention-prebuild-wheels, then tries official Dao-AILab/flash-attention release wheels with both cxx11abi variants, and finally falls back to source compilation via pip install flash-attn --no-build-isolation.

🚀 Quick Start

Hardware Notes

📖 For full CLI options, device setup, offload strategies, caching acceleration, Torch Compile, FP8, and batch inference details, see INFERENCE_GUIDE.md. Torch Compile note: --enable_torch_compile can occasionally produce all-black outputs on some GPUs/models. If that happens, disable it first.

⚠️ Responsible AI & Limitations

Responsible AI

Boogu-Image-0.1 is released for research purposes and is not intended for production deployment without additional safeguards. We took responsible-AI considerations into account during data curation, training, and evaluation; however the model may still produce outputs that are inaccurate, biased, or otherwise inappropriate.

Known Limitations

🌍 World Knowledge Gap

• For tasks requiring rich common sense, domain knowledge, real brands or people, famous landmarks, celebrities, products, or complex contextual understanding, Boogu still has a clear gap from strong closed-source systems
• This capability is extraordinarily expensive to measure; even Arena-style evaluation struggles to assess it fully, so existing benchmarks barely quantify this dimension and the real gap is likely larger than measured scores suggest

🖼️ Image-to-Image Consistency & In-Context Scenarios

• For editing tasks requiring strict preservation of the input subject, identity, layout, or fine details, Boogu's image-to-image consistency is still not stable enough
• Because our image-to-image capability focuses more on photography and text-generation applications, Boogu still trails Seedream 5.0 and Nano Banana Pro in some in-context generation scenarios

📝 Text Rendering Stability

• Boogu can handle many Chinese and English text scenarios, but long text, dense typography, small fonts, and complex design layouts can still produce typos, missing characters, or layout drift
• Text rendering is currently focused on Chinese and English; other languages are not specifically optimized and may degrade noticeably

🦴 Body Structure in Complex Poses

• In multi-person interaction, occlusion, exaggerated motion, or unusual viewpoints, hands, limbs, and body structure may still become unnatural or inconsistent

👤 Small Faces & Small Limbs

• Because we use the open-source FLUX.1 VAE, reconstruction loss is relatively large, so details such as small faces, small limbs, eyes, and text may still show artifacts or instability

📦 Limited Release Scope

• Due to resource constraints, engineering complexity, and release boundaries, we are not able to open-source every training and system detail
• The current open-source release aims to balance reproducibility, usability, and sustainable maintenance while providing a reliable starting point for community research and improvement

Downstream users are responsible for applying content moderation, validation, and compliance checks appropriate to their use case.

🙏 Acknowledgements

Closed-source systems such as GPT-Image, Nano Banana, and the Seedream series helped us understand the frontier capabilities and practical boundaries of unified understanding-and-generation systems. We thank the Qwen-Image, Z-Image, OmniGen2, FLUX, Lumina-Image-2.0 and broader open-source communities for the foundations they provide, and DeepSeek for strong open-source understanding models that support open-source unified multimodal systems.
