Welcome to the official repository for **Boogu-Image-0.1** !

English | [中文](./README_CN.md)

## 📖 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 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.**

## 🛠️ Installation

> **Tested environment:** Python 3.10 · CUDA 12.6 · PyTorch 2.7.1

```bash
# 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
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:

```bash
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
```



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

```bash
# 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`](https://github.com/mjun0812/flash-attention-prebuild-wheels), then tries official [`Dao-AILab/flash-attention`](https://github.com/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

### PyTorch Native T2I Inference

```bash
export device="cuda:0" # Required

# Prompt enhancement is powered by an instruction reasoner, also called the rewriter.
# We provide two ways to use it:
#
# 1. Standalone external rewriter:
#    See utils/t2i_external_prompt_rewriter.py. This is a pure external mode example and
#    requires enough GPU memory, without advanced memory management.
#    python utils/t2i_external_prompt_rewriter.py --prompt "draw a cat" --model /path/to/Qwen3-VL-32B-Instruct --lang en
#
# 2. Pipeline-integrated rewriter:
#    See the scripts under `demo_scripts` whose names contain "reasoning".
#    For example: demo_scripts/demo_t2i_local_reasoning.sh
#    This mode supports more flexible memory management. Set the generation and
#    rewriter devices manually, then pass them to inference.py:
#    export device="cuda:0"
#    export rewriter_device="cuda:1"
#    python inference.py --device $device --rewriter_device $rewriter_device ...
#    For more details, see INFERENCE_GUIDE.md.

### Hardware Notes

> 📖 For full CLI options, device setup, offload strategies, caching acceleration, Torch Compile, FP8, and batch inference details, see [**INFERENCE_GUIDE.md**](./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

**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.
