HunyuanOCR 1.5: Making Lightweight OCR VLMs Faster and Better 🤗 HF Model 💻 GitHub Repo 📄 Paper 📦 Model layout. This repository hosts HunyuanOCR 1.5 checkpoint at the root (target base weights). The DFlash speculative decoding draft lives under dflash/ , and the previous HunyuanOCR 1.0 is archived under v1.0/ (load it with subfolder="v1.0" , or download the v1.0/ directory directly). 📖 Introduction HunyuanOCR 1.5 is a lightweight, end to end OCR specialized vision language model. It targets a broad range of text centric visual tasks and unifies document parsing, text spotting, information extraction, text image translation within a single end to end VLM. Building upon the validated lightweight architecture of HunyuanOCR 1.0, HunyuanOCR 1.5 does not redesign the model backbone. Instead, it performs a systematic upgrade around two goals — making the model faster and better : ⚡ Faster — DFlash inference acceleration. End to end OCR is often accompanied by long autoregressive decoding, which becomes the major bottleneck for dense documents, tables, formulas, and other long structured outputs. HunyuanOCR 1.5 adapts a speculative decoding framework based on DFlash : a lightweight blo…
