A small 0.8B OCR model from LightOn that reads a page image into markdown, and in grounding mode also labels each block with a bounding box. The fast, light size of the LightOnOCR-3 family. LightOnOCR-3-0.8B is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by lightonai ## About ### What it is LightOnOCR-3-0.8B is the smallest model in LightOn's LightOnOCR-3 family of OCR models. It reads an image of a page and writes out the text, and it can also say where each block sits on the page. It is one model rather than a multi-step document pipeline. The card says it copes with receipts and forms, tables and charts, pages laid out in columns, and mathematical formulas. The 0.8B size follows the Qwen3.5 vision-language design, which the card says eases integration and speeds it up. ### Who it suits Developers who need fast OCR and page understanding in their own apps, and teams who digitize documents and want structured output without a large model. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Finance | Back-office teams | Read receipts and forms | Turning scanned receipts into text | | Legal and admin | Records teams | Digitize multi-column documents | Converting printed reports to markdown | | Software | App developers | Add page understanding to a product | Extracting tables from uploaded pages | | Research | Data teams | Pull chart data into tables | Turning a chart image into a data table | You can skip it if you need the highest accuracy, since the card names the 4B model as the best for most tasks, or if you only process plain text files. ### Where to use it It loads through the transformers library in Python, and the family also offers 1B and 4B sizes. - Python with transformers - Windows, macOS and Linux - Pipelines that feed page images in and take markdown out | Use case | Who | What they get back | | --- | --- | --- | | Page transcription | Developers | The page text as markdown | | Layout grounding | Data teams | Each block with a label and bounding box | | Chart to table | Analysts | An HTML table of the chart's data points | | Image captions | Retrieval teams | A short description of each picture | ### How to set it up You need Python and the Hugging Face tools. The model is small, at about 1.7 GB in BF16, so most modern machines can hold it. - Python with pip and transformers - About 1.7 GB of disk space - A GPU is helpful for speed 1. Install the Hugging Face hub tools with pip. 2. Download the model files with the hf command. 3. Load the model with transformers and pass it a page image. ```sh pip install -U huggingface_hub hf download lightonai/LightOnOCR-3-0.8B ``` ### How to use it Pass a page image with an empty prompt to get the page text as markdown, the default mode and the same as LightOnOCR-2. Pass the word grounding as the prompt to get labels and boxes too. | Mode | What you get | | --- | --- | | Empty prompt | All text on the page as markdown | | grounding prompt | Each block with a label and a bounding box, plus image descriptions and chart tables | In grounding mode each block starts with a placeholder showing its type and box, in page coordinates scaled from 0 to 1000. The card's example looks like this. ```text ![title](80,70,920,140) # Company report 2025 ![text](80,175,920,225) Revenue rose 20%. ![image](80,285,460,545) A solar-powered factory. ![chart](540,285,920,545)

``` ### Example You send an image of a company report page with the grounding prompt. You get a title block, a text block saying revenue rose 20 percent, an image block with a short description and a chart block as a table. ### For newcomers and experts If you are new, start with the empty prompt on one clear page image and read the markdown it returns. Try the grounding prompt next to see labels and boxes. If you know the field, the block labels include text, title, list, header, footer, page number, footnote, caption, formula, code and table, plus image and chart blocks. Boxes use coordinates normalized to 0 to 1000, so they are independent of image size. Page image in → Empty or grounding prompt → Model reads layout and text → Markdown out, with labels and boxes in grounding mode ### Good to know The family has three sizes, and the 0.8B is the fast, efficient one. The card says all models are released under Apache 2.0 for research and commercial use. - License: Apache 2.0, for research and commercial use - Cost to run: none named - Data it reaches: the page images you give it, and the model files you download - Not for: the highest accuracy, since the card recommends the 4B model for most tasks ## README ````markdown # LightOnOCR-3-0.8B A small 0.8B OCR model from LightOn that reads a page image into markdown, and in grounding mode also labels each block with a bounding box.
