It does layout grounding, so the result stays tied to how the page is laid out. It demonstrates the LightOnOCR-3 model, which the Space names in 4B, 1B and 0.8B sizes. The Space runs on Hugging Face, so you can try it in a browser with nothing to install. ### Who it suits People who need the text of scanned or photographed pages in an editable form, and developers who want to try an OCR model before building on it. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Document processing | Office teams | Turn a scanned page into Markdown text | Drop one page and read the Markdown | | Records and archives | Archivists | Digitize printed pages into text | Try a page from the examples folder | | Software | Developers | Compare the three model sizes on the same page | Run one page against each size the Space names | | Research | OCR researchers | Look at how layout grounding ties text to the page | Open a page and inspect the grounded output | Anyone who only needs to read pages by eye can skip it. ### Where to use it It runs in these places. - A web browser, on the Space's page at Hugging Face - Windows, with Python 3.12 - macOS, with Python 3.12 - Linux, with Python 3.12 | Use case | Who | What they get back | | --- | --- | --- | | Convert a page to Markdown | Office teams | The page text as Markdown | | Check the layout grounding | Researchers | Output tied to the page layout | | Reuse the app code | Developers | A local copy with ocr.py and grounding.py to read | ### How to set it up Using the Space online needs only a browser. A copy on your own computer needs the following. - Python 3.12 and pip - The huggingface\_hub package, which gives you the hf command - Disk space for the repository, which holds 38 files 1. Install the huggingface\_hub package. 2. Download the Space's files into a local folder. 3. Move into that folder. 4. Install Gradio at the version the Space uses, then install the packages in requirements.txt. 5. Start the app. ```sh pip install -U huggingface_hub hf download lightonai/LightOnOCR-3-Demo --repo-type space --local-dir LightOnOCR-3-Demo cd LightOnOCR-3-Demo pip install gradio==6.29.1 pip install -r requirements.txt python app.py ``` ### How to use it Open the Space's page, or run the app on your computer and open the page Gradio shows. Drop in a page image and read the Markdown that comes back. ```sh python app.py ``` | Tool | What it does | | --- | --- | | app.py | The main file, it builds the Gradio page | | ocr.py | Holds the code that reads the page | | grounding.py | Holds the layout grounding code | | examples folder | Holds sample pages to try | ### Example You drop in a scanned page of a printed report. You get back the page as Markdown, with the layout grounding applied to it. ### For newcomers and experts OCR means reading the text out of a picture of a page. The first small thing to try is the online Space with one of the sample pages. The Space names three sizes of LightOnOCR-3, at 4B, 1B and 0.8B. The code is split into ocr.py, grounding.py and render.py. The hosted copy is set to run on Hugging Face's zero-a10g hardware. You drop in a page image → The LightOnOCR-3 model reads the page → Layout grounding ties text to the page → The app shows Markdown ### Good to know The Space states no usage limits, so treat it as a demo you can read and adapt. - License: apache-2 - Cost to run: none named - Data it reaches: the page images you drop in, plus the Space files and model files that Hugging Face supplies - Hardware: the Space is set to zero-a10g at Hugging Face, and what your own computer needs is not stated ## README ````markdown # LightOnOCR-3 Demo Reads a page image and returns its text as Markdown, with layout grounding.
