## News🔥🔥🔥

**[2025.02]** We open-source three composition-aware reward models in [HuggingFace Repo](https://huggingface.co/comin/IterComp/tree/main/reward_models), which can be used for preference learning and as **new image generation evaluators**.

**[2025.02]** We enhance IterComp-RPG with LLMs that possess the strongest reasoning capabilities, including [**DeepSeek-R1**](https://github.com/deepseek-ai/DeepSeek-R1), [**OpenAI o3-mini**](https://openai.com/index/openai-o3-mini/), and [**OpenAI o1**](https://openai.com/index/learning-to-reason-with-llms/) to achieve outstanding compositional image generation under complex prompts.

**[2025.01]** IterComp is accepted by ICLR 2025!!!

**[2024.10]** Checkpoints of base diffusion model are publicly available on [HuggingFace Repo](https://huggingface.co/comin/IterComp).

**[2024.10]** Our main code of IterComp is released.

## Introduction

IterComp is one of the new State-of-the-Art compositional generation methods. In this repository, we release the model training from  [SDXL Base 1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0) .

## Text-to-Image Usage

```python
from diffusers import DiffusionPipeline
import torch

pipe = DiffusionPipeline.from_pretrained("comin/IterComp", torch_dtype=torch.float16, use_safetensors=True)
pipe.to("cuda")
# if using torch < 2.0
# pipe.enable_xformers_memory_efficient_attention()

prompt = "An astronaut riding a green horse"
image = pipe(prompt=prompt).images[0]
image.save("output.png")
```

IterComp can **serve as a powerful backbone for various compositional generation methods**, such as [RPG](https://github.com/YangLing0818/RPG-DiffusionMaster) and [Omost](https://github.com/lllyasviel/Omost). We recommend integrating IterComp into these approaches to achieve more advanced compositional generation results.
