Its mission is to help AI technology quickly land, and its vision is to make everyone an AI Developer! PaddleX currently covers areas such as image classification, object detection, image segmentation, 3D, OCR, and time series prediction, and has built-in 36 basic single models, such as RP-DETR, PP-YOLOE, PP-HGNet, PP-LCNet, PP- LiteSeg, etc.; integrated 12 practical industrial solutions, such as PP-OCRv4, PP-ChatOCR, PP-ShiTu, PP-TS, vehicle-mounted road waste detection, identification of prohibited wildlife products, etc. PaddleX provides two AI development modes: "Toolbox" and "Developer". The toolbox mode can tune key hyperparameters without code, and the developer mode can perform single-model training, push and multi-model serial inference with low code, and supports both cloud and local terminals. PaddleX also supports joint innovation and development, profit sharing! At present, PaddleX is rapidly iterating, and welcomes the participation of individual developers and enterprise developers to create a prosperous AI technology ecosystem! 📚 E-book: Dive Into OCR Dive Into OCR 🛠️ PP-OCR Series Model List（Update on September 8th） Model introduction Model name Recommended scene Detection model Direction classifier Recognition model Chinese and English ultra-lightweight PP-OCRv4 model（16.2M） ch_PP-OCRv4_xx Mobile & Server inference model / trained model inference model / trained model inference model / trained model Chinese and English ultra-lightweight PP-OCRv3 model（16.2M） ch_PP-OCRv3_xx Mobile & Server inference model / trained model inference model / trained model inference model / trained model English ultra-lightweight PP-OCRv3 model（13.4M） en_PP-OCRv3_xx Mobile & Server inference model / trained model inference model / trained model inference model / trained model For more model downloads (including multiple languages), please refer to PP-OCR series model downloads.
