## 📢 News - [x] **[2025.01.06]** Release the code and models of ACE++. - [x] **[2025.01.07]** Release the demo on HuggingFace. - [] **[ToDo]** Update New Models. ## 🔥 ACE Models ACE++ provides a comprehensive toolkit for image editing and generation to support various applications. We encourage developers to choose the appropriate model based on their own scenarios and to fine-tune their models using data from their specific scenarios to achieve more stable results. ### ACE++ Portrait Portrait-consistent generation to maintain the consistency of the portrait.

Tuning Method	Input	Output	Instruction	Models
LoRA + ACE Data			"Maintain the facial features. A girl is wearing a neat police uniform and sporting a badge. She is smiling with a friendly and confident demeanor. The background is blurred, featuring a cartoon logo."

Models' scepter_path: - **ModelScope:** ms://iic/ACE_Plus@portrait/xxxx.safetensors - **HuggingFace:** hf://ali-vilab/ACE_Plus@portrait/xxxx.safetensors ### ACE++ Subject Subject-driven image generation task to maintain the consistency of a specific subject in different scenes.

Tuning Method	Input	Output	Instruction	Models
LoRA + ACE Data			"Display the logo in a minimalist style printed in white on a matte black ceramic coffee mug, alongside a steaming cup of coffee on a cozy cafe table."

Models' scepter_path: - **ModelScope:** ms://iic/ACE_Plus@subject/xxxx.safetensors - **HuggingFace:** hf://ali-vilab/ACE_Plus@subject/xxxx.safetensors ### ACE++ LocalEditing Redrawing the mask area of images while maintaining the original structural information of the edited area.

Tuning Method	Input	Output	Instruction	Models
LoRA + ACE Data			"By referencing the mask, restore a partial image from the doodle {image} that aligns with the textual explanation: "1 white old owl"."

Models' scepter_path: - **ModelScope:** ms://iic/ACE_Plus@local_editing/xxxx.safetensors - **HuggingFace:** hf://ali-vilab/ACE_Plus@local_editing/xxxx.safetensors ### ACE++ Fully [Coming soon] Fully finetuning a composite model with ACE’s data to support various editing and reference generation tasks through an instructive approach. ## 🔥 Applications The ACE++ model supports a wide range of downstream tasks through simple adaptations. Here are some examples, and we look forward to seeing the community explore even more exciting applications utilizing the ACE++ model.

Application	ACE++ Model
Try On	ACE++ Subject	"The woman dresses this skirt."
Logo Paste	ACE++ Subject	"The logo is printed on the headphones."
Photo Editing	ACE++ Subject	"The item is put on the ground."
Movie Poster Editor	ACE++ Portrait	"The man is facing the camera and is smiling."

## ⚙️️ Installation Download the code using the following command: ```bash git clone https://github.com/ali-vilab/ACE_plus.git ``` Install the necessary packages with `pip`: ```bash cd ACE_plus pip install -r requirements.txt ``` ACE++ depends on FLUX.1-Fill-dev as its base model, which you can download from [![HuggingFace link](https://img.shields.io/badge/%F0%9F%A4%97%20Hugging%20Face-Model-yellow)](https://huggingface.co/black-forest-labs/FLUX.1-Fill-dev). In order to run the inference code or Gradio demo normally, we have defined the relevant environment variables to specify the location of the model. For model preparation, we provide three methods for downloading the model. The summary of relevant settings is as follows. | Model Downloading Method | Clone to Local Path | Automatic Downloading during Runtime

| ## 🚀 Inference Under the condition that the environment variables defined in [Installation](#-installation), users can run examples and test your own samples by executing infer.py. The relevant commands are as follows: ```bash export FLUX_FILL_PATH="hf://black-forest-labs/FLUX.1-Fill-dev" export PORTRAIT_MODEL_PATH="ms://iic/ACE_Plus@portrait/comfyui_portrait_lora64.safetensors" export SUBJECT_MODEL_PATH="ms://iic/ACE_Plus@subject/comfyui_subject_lora16.safetensors" export LOCAL_MODEL_PATH="ms://iic/ACE_Plus@local_editing/comfyui_local_lora16.safetensors" # Use the model from huggingface # export PORTRAIT_MODEL_PATH="hf://ali-vilab/ACE_Plus@portrait/comfyui_portrait_lora64.safetensors" # export SUBJECT_MODEL_PATH="hf://ali-vilab/ACE_Plus@subject/comfyui_subject_lora16.safetensors" # export LOCAL_MODEL_PATH="hf://ali-vilab/ACE_Plus@local_editing/comfyui_local_lora16.safetensors" python infer.py ``` ## 💻 Demo We have built a GUI demo based on Gradio to help users better utilize the ACE++ model. Just execute the following command. ```bash export FLUX_FILL_PATH="hf://black-forest-labs/FLUX.1-Fill-dev" export PORTRAIT_MODEL_PATH="ms://iic/ACE_Plus@portrait/comfyui_portrait_lora64.safetensors" export SUBJECT_MODEL_PATH="ms://iic/ACE_Plus@subject/comfyui_subject_lora16.safetensors" export LOCAL_MODEL_PATH="ms://iic/ACE_Plus@local_editing/comfyui_local_lora16.safetensors" # Use the model from huggingface # export PORTRAIT_MODEL_PATH="hf://ali-vilab/ACE_Plus@portrait/comfyui_portrait_lora64.safetensors" # export SUBJECT_MODEL_PATH="hf://ali-vilab/ACE_Plus@subject/comfyui_subject_lora16.safetensors" # export LOCAL_MODEL_PATH="hf://ali-vilab/ACE_Plus@local_editing/comfyui_local_lora16.safetensors" python demo.py ``` ## 📚 Limitations * For certain tasks, such as deleting and adding objects, there are flaws in instruction following. For adding and replacing objects, we recommend trying the repainting method of the local editing model to achieve this. * The generated results may contain artifacts, especially when it comes to the generation of hands, which still exhibit distortions. * The current version of ACE++ is still in the development stage. We are working on improving the model's performance and adding more features. ## 📝 Citation ACE++ is a post-training model based on the FLUX.1-dev series from black-forest-labs.
