# PP-OCRv6 Tiny Rec — ONNX

ONNX export of [PaddlePaddle/PP-OCRv6_tiny_rec_onnx](https://huggingface.co/PaddlePaddle/PP-OCRv6_tiny_rec_onnx), the lightweight tiny text recognition model from PaddleOCR PP-OCRv6 (~4.5 MB). Features a compact 6,904-character CTC dictionary.

Mirrored for use with [inference4j](https://github.com/inference4j/inference4j), an inference-only AI library for Java.
