PaddlePaddle releases HPD-Parsing, a 1B model with hierarchical parallel decoding

PaddlePaddle has introduced HPD-Parsing, a lightweight 1-billion parameter document parsing model that utilizes a Hierarchical Parallel Decoding paradigm to improve throughput. The architecture coordinates global page structure through a main layout branch while dispatching localized content generation to concurrent branches, utilizing Progressive Multi-Token Prediction to reduce decoding steps.
