+## 📌 Model Summary
+
+**HiFi-Inpaint** is a reference-based human-product image inpainting model for generating detail-preserving human-product images. Given a product reference image, a masked condition image, and a text prompt/caption, the model is designed to reconstruct the missing region while preserving fine-grained product appearance.
+
+This repository contains the released model weights for HiFi-Inpaint, intended for research and model development on high-fidelity reference-guided inpainting.

+
+- `pytorch_lora_weights.safetensors`: LoRA weights for the HiFi-Inpaint model.
+- `alpha_blocks.pt`: auxiliary alpha-block weights used by the HiFi-Inpaint model pipeline.
+
+## 🎯 Intended Uses
+
+HiFi-Inpaint is intended for **research and model development** on reference-based human-product generation and inpainting. Typical use cases include:
+
+- Product-reference-guided image inpainting.
+- Generating detail-preserving human-product images.
+- Fine-tuning or analyzing reference-conditioned image generation pipelines.
+- Studying product appearance preservation under masked-image reconstruction settings.
+
+This model is released as research weights and is not intended for deceptive, harmful, privacy-violating, or otherwise unlawful applications.
+
+## 💻 How to Use
+
+Please refer to the official code repository for installation, pipeline construction, and inference scripts:
+
+https://github.com/Correr-Zhou/HiFi-Inpaint
+
+A typical setup should download this repository's weights and load:
+
+- `pytorch_lora_weights.safetensors` as the LoRA checkpoint.
+- `alpha_blocks.pt` as the auxiliary alpha-block checkpoint required by the inference pipeline.
+
+## 📚 Training Data
+
+The model is associated with **HP-Image-40K**, a training dataset for high-fidelity reference-based human-product image inpainting. The dataset contains **43,632** aligned training samples with product reference images, ground-truth target images, masked condition images, binary masks, and captions.
+
+Dataset repository: https://huggingface.co/datasets/donghao-zhou/HP-Image-40K
+
+## ⚖️ Usage Note
+
+This model is released for **research and model development** purposes.
+
+- Users should ensure that downstream use complies with the model license, dataset license, and applicable regulations.
+- The model should not be used for deceptive, harmful, or privacy-violating applications.
+- Generated outputs should be reviewed before public or commercial use.
