👏We just released OCRflux — a multimodel PDF-to-Markdown toolkit that handles multi-column layouts, table parsing & cross-page merging. 🔵Built on top of finetuning the multimodal LLM Qwen2.5-VL-3B-Instruct, it delivers 3× higher throughput on a GTX 3090 GPU than the olmOCR-7B baseline model. 🔵It achieves 0.967 Edit Distance Similarity vs olmOCR’s 0.872 vs Nanonets's 0.858.

卧槽, 真的 SOTA 了, 正在准备做一个 PDF 转 Markdown 的领域大模型评测, 结果我发现 ChatDOC 的 OCRFlux-3B 在我测试的所有场景均达到了现阶段最理想的效果. 下面直接为大家带来实测: 场景A: 让我们直接来现阶段的 PDF 转化试金石——发票转 Markdown 可以看到, 重要的 购买方, 单价, 价税合计, 销售方均十分准确, 并且没有把印章错误的当成内容. 而且形成的 Markdown 表格行列准确, 甚至还有合并单元格的表格. 以往的测试别说表格, 连内容都不一定识别准确. 更别提生成正确的 Markdown 表格了. 当然也不是没有瑕疵. 如果 OCRFlux 可以把表头和页脚也能准确识别进去就完美了. 现在生成的内容用来识别普票还是专票还是有困难的. #OCRFlux #ChatDOC #Markdown #PDF

PDF parsing is still painful because LLMs reorder text in complex layouts, break tables across pages, and fail on graphs or images. 💡Testing the new open-source OCRFlux model, and here the results are really good for a change. So OCRFlux is a multimodal, LLM based toolkit for converting PDFs and images into clean, readable, plain Markdown text. Because the underlying VLM is only 3B param, it runs even on a 3090 GPU. The model is available on @huggingface . The engine that powers the OCRFlux, teaches the model to rebuild every page and then stitch fragments across pages into one clean Markdown file. It bundles one vision language model with 3B parameters that was fine-tuned from Qwen 2.5-VL-3B-Instruct for both page parsing and cross-page merging. OCRFlux reads raw page images and, guided by task prompts, outputs Markdown for each page and merges split elements across pages. The evaluation shows Edit Distance Similarity (EDS) 0.967 and cross‑page table Tree Edit Distance 0.950, so the parser is both accurate and layout aware. How it works while parsing each page - Convert into text with a natural reading order, even in the presence of multi-column layouts, figures, and insets - Support for complicated tables and equations - Automatically removes headers and footers Cross-page table/paragraph merging - Cross-page table merging - Cross-page paragraph merging A compact vision‑language models can beat bigger models once cross‑page context is added. 🧵 1/n Read on 👇

PDFの常識を変える?!🤯✨ 新ツール「OCRFlux」が登場しましたよ! ✎. FYIG: xitter.cf/aigclink/status/193818… PDFをMarkdownに変換する新しいツール「OCRFlux」が発表されたそうです!これがもう、すごい機能満載なんですって! 一番驚いたのは、PDFでページをまたぐ表や段落を、自動で繋げてMarkdownにしてくれること!😲 これって、今まで手作業で調整していた部分ですよね。論文や長い報告書を扱う方には、革命的な機能なんじゃないでしょうか?! なんと98.3%という驚異の正確率なんですって!✨ しかも、多列レイアウトや、中国語と英語が混ざったドキュメントまで、ちゃんと自然な読み順で変換してくれるそうですよ。グローバルな資料作成にも心強いですね! 他の有名なOCRツールと比べても、ベンチマークで圧倒的な性能を示しているとのこと!そして、GTX 3090などのGPUがあれば、3Bパラメータモデルでめちゃくちゃ高速に処理できちゃうそうです!🚀 作業効率がグンと上がりそうでワクワクしますね! 実際の変換の様子は動画で見られますが、まるで魔法みたいにサクサク動いていましたよ!これがあれば、PDFからのデータ抽出や再利用が格段にラクになりますよね。 例えば、古いPDF資料をMarkdown化して検索しやすくしたり、議事録をPDFでもらってもすぐに編集可能なテキストに変換したり…アイデア次第で色々な使い方ができそうです! 詳しい情報や、もしかしたら試せるデモもあるかもしれませんね!ぜひチェックしてみてください! PDFを扱う皆さんの救世主になるかもしれませんね!これからが本当に楽しみです!😊 #OCRFlux #PDF変換 #AIツール
