OFA-Sys/Chinese-CLIP

Chinese-CLIP provides pretrained models and Python APIs for Chinese image-text feature extraction, similarity scoring, cross-modal retrieval, and zero-shot classification. It is intended for developers and researchers working with Chinese-language vision-language tasks who have access to GPU hardware.

Project overview

Project type: Data Processing · Image & Vision
Use cases: Search & Research · Learning & Education
Deployment: Refer to project documentation
License: MIT

Best for

Developers and researchers building Chinese-language vision-language retrieval or zero-shot classification applications.
Teams requiring fine-tuning scripts for pretrained Chinese image-text models.

Key capabilities

Extracts image and Chinese text feature vectors and calculates their similarity through a Python API.
Provides workflows for text-to-image and image-to-text retrieval, including top-k predictions.
Provides code and evaluation workflows for zero-shot image classification using Chinese prompts and labels.
Provides example scripts for fine-tuning pretrained Chinese-CLIP models, including distributed training support.

Limitations and risks

The provided KNN retrieval implementation is described for small-scale academic retrieval datasets.
A Chinese-CLIP pretrained checkpoint is required for documented fine-tuning and evaluation workflows, and a GPU is required for operation.

Getting started

Install the cn_clip package via pip, load a named Chinese-CLIP model through the Python API, and provide an image and Chinese text to extract features and calculate similarity.
