InstantID is a new state-of-the-art tuning-free method to achieve ID-Preserving generation with only single image, supporting various downstream tasks.
- [2024/04/03] 🔥 We release our recent work InstantStyle for style transfer, compatible with InstantID!
- [2024/02/01] 🔥 We have supported LCM acceleration and Multi-ControlNets on our Huggingface Spaces Demo! Our depth estimator is supported by Depth-Anything.
- [2024/01/31] 🔥 OneDiff now supports accelerated inference for InstantID, check this for details!
- [2024/01/23] 🔥 Our pipeline has been merged into diffusers!
- [2024/01/22] 🔥 We release the pre-trained checkpoints, inference code and gradio demo!
- [2024/01/15] 🔥 We release the technical report.
- [2023/12/11] 🔥 We launch the project page.
Comparison with existing tuning-free state-of-the-art techniques. InstantID achieves better fidelity and retain good text editability (faces and styles blend better).
Comparison with pre-trained character LoRAs. We don't need multiple images and still can achieve competitive results as LoRAs without any training.
Comparison with InsightFace Swapper (also known as ROOP or Refactor). However, in non-realistic style, our work is more flexible on the integration of face and background.
You can directly download the model from Huggingface. You also can download the model in python script:
from huggingface_hub import hf_hub_download
hf_hub_download(repo_id="InstantX/InstantID", filename="ControlNetModel/config.json", local_dir="./checkpoints")
hf_hub_download(repo_id="InstantX/InstantID", filename="ControlNetModel/diffusion_pytorch_model.safetensors", local_dir="./checkpoints")
hf_hub_download(repo_id="InstantX/InstantID", filename="ip-adapter.bin", local_dir="./checkpoints")Or run the following command to download all models:
pip install -r gradio_demo/requirements.txt
python gradio_demo/download_models.pyIf you cannot access to Huggingface, you can use hf-mirror to download models.
export HF_ENDPOINT=https://hf-mirror.com
huggingface-cli download --resume-download InstantX/InstantID --local-dir checkpoints --local-dir-use-symlinks FalseFor face encoder, you need to manually download via this URL to models/antelopev2 as the default link is invalid. Once you have prepared all models, the folder tree should be like:
.
├── models
├── checkpoints
├── ip_adapter
├── pipeline_stable_diffusion_xl_instantid.py
└── README.md
If you want to reproduce results in the paper, please refer to the code in infer_full.py. If you want to compare the results with other methods, even without using depth-controlnet, it is recommended that you use this code.
If you are pursuing better results, it is recommended to follow InstantID-Rome.
The following code👇 comes from infer.py. If you want to quickly experience InstantID, please refer to the code in infer.py.

# prepare models under ./checkpoints

pipe.cuda()
# load adapter
pipe.load_ip_adapter_instantid(face_adapter)Then, you can customized your own face images
# load an image
face_image = load_image("./examples/yann-lecun_resize.jpg")
# prepare face emb
face_info = app.get(cv2.cvtColor(np.array(face_image), cv2.COLOR_RGB2BGR))
face_info = sorted(face_info, key=lambda x:(x['bbox'][2]-x['bbox'][0])*(x['bbox'][3]-x['bbox'][1]))[-1] # only use the maximum face
face_emb = face_info['embedding']
face_kps = draw_kps(face_image, face_info['kps'])
# prompt
prompt = "film noir style, ink sketch|vector, male man, highly detailed, sharp focus, ultra sharpness, monochrome, high contrast, dramatic shadows, 1940s style, mysterious, cinematic"
negative_prompt = "ugly, deformed, noisy, blurry, low contrast, realism, photorealistic, vibrant, colorful"
# generate image

).images[0]To save VRAM, you can enable CPU offloading
pipe.enable_model_cpu_offload()
pipe.enable_vae_tiling()Our work is compatible with LCM-LoRA. First, download the model.
from huggingface_hub import hf_hub_download
hf_hub_download(repo_id="latent-consistency/lcm-lora-sdxl", filename="pytorch_lora_weights.safetensors", local_dir="./checkpoints")To use it, you just need to load it and infer with a small num_inference_steps. Note that it is recommendated to set guidance_scale between [0, 1].
from diffusers import LCMScheduler
lcm_lora_path = "./checkpoints/pytorch_lora_weights.safetensors"
pipe.load_lora_weights(lcm_lora_path)
pipe.fuse_lora()
pipe.scheduler = LCMScheduler.from_config(pipe.scheduler.config)
num_inference_steps = 10
guidance_scale = 0
Run the following command:
python gradio_demo/app.pyor MultiControlNet version:
gradio_demo/app-multicontrolnet.py - For higher similarity, increase the weight of controlnet_conditioning_scale (IdentityNet) and ip_adapter_scale (Adapter).
- For over-saturation, decrease the ip_adapter_scale. If not work, decrease controlnet_conditioning_scale.
- For higher text control ability, decrease ip_adapter_scale.
- For specific styles, choose corresponding base model makes differences.
- We have not supported multi-person yet, only use the largest face as reference facial landmarks.
- We provide a style template for reference.
- InstantID is developed by InstantX Team, all copyright reserved.
- Our work is highly inspired by IP-Adapter and ControlNet. Thanks for their great works!
- Thanks Yamer for developing YamerMIX, we use it as base model in our demo.
- Thanks ZHO-ZHO-ZHO, huxiuhan, sdbds, zsxkib for their generous contributions.
- Thanks to the HuggingFace gradio team for their free GPU support!
