ONNX exports of PaddlePaddle document models, one flat file per model. MANIFEST.txt lists the sha256 of every file. All files are Apache-2.0.

File	Model	Source
`PP-DocLayoutV3_fp32_batchable.onnx`	layout detection	`PaddlePaddle/PP-DocLayoutV3_onnx`, output reshaped to `[B,300,7]`
`PP-OCRv6_{tiny,small,medium}_det.onnx`	text detection	`PaddlePaddle/PP-OCRv6_*_det_onnx`, unchanged
`PP-OCRv6_{tiny,small,medium}_rec_ctc.onnx`	text recognition	`PaddlePaddle/PP-OCRv6_*_rec_onnx`, plus `ctc_idx` / `ctc_prob` outputs (argmax and max over the class axis)
`SLANet_plus_encoder.onnx`, `SLANet_plus_decoder.bin`	table structure	`PaddlePaddle/SLANet_plus_onnx`: the encoder graph, and the GRU decoder's weights as raw float32
`PP-FormulaNet_plus-{M,S}_{encoder,prep,decoder_step}.onnx`, `_tokenizer.json`	formula recognition	`PaddlePaddle/PP-FormulaNet_plus-M` / `-S`, split into encoder, cross-attention precompute and one greedy decoder step over a static KV cache
`PP-DocLayoutV3_fp32_batchable_fp16.onnx`, `PP-OCRv6_{tiny,small,medium}_rec_ctc_fp16.onnx`	FP16 graphs for ONNX Runtime's TensorRT provider	derived from the FP32 file of this repository by `convert_fp16.py` (onnx 1.21.0, onnxconverter-common 1.16.0; I/O stay FP32)
