PP-OCRv6_det_tiny.onnx is the unchanged pretrained detector.
PP-OCRv6_rec_tiny.onnx WAS MODIFIED by Maureese Williams in 2026:
selected float32 weight tensors were stored as per-channel int8 values with
constant decoding back to float32. Computation remains float32. No training
or calibration was performed. This modified file is not an official
PaddlePaddle release. SHA-256 hashes and origins are in assets/models.json.

Original ONNX artifacts were distributed through RapidAI/RapidOCR v3.10.0:
