## Introduction
**dots.ocr** Designed for universal accessibility, it possesses the capability to recognize virtually any human script. Beyond achieving state-of-the-art (SOTA) performance in standard multilingual document parsing among models of comparable size, dots.ocr-1.5 excels at converting structured graphics (e.g., charts and diagrams) directly into SVG code, parsing web screens and spotting scene text.
## News
* ```2026.2.16 ``` 🚀 We release [dots.ocr-1.5](https://huggingface.co/rednote-hilab/dots.ocr-1.5), designed to recognize all human scripts and symbols. This model extends beyond standard document parsing to include comprehensive image parsing. We are simultaneously releasing [dots.ocr-1.5-svg](https://huggingface.co/rednote-hilab/dots.ocr-1.5-svg), which offers more robust performance for image parsing tasks.
* ```2025.10.31 ``` 🚀 We release [dots.ocr.base](https://huggingface.co/rednote-hilab/dots.ocr.base), foundation VLM focus on OCR tasks, also the base model of [dots.ocr](https://huggingface.co/rednote-hilab/dots.ocr). Try it out!
* ```2025.07.30 ``` 🚀 We release [dots.ocr](https://huggingface.co/rednote-hilab/dots.ocr), — a multilingual documents parsing model based on 1.7b llm, with SOTA performance.

### 2. Vision-Language Parsing
Visual languages (e.g., charts, graphics, chemical formulas, logos) encapsulate dense human knowledge. **dots.ocr-1.5** unifies the interpretation of these elements by parsing them directly into **SVG code**.

> **Note:**
> - We use the ISVGEN metric from [UniSVG](https://ryanlijinke.github.io/) to evaluate the parsing result. For benchmarks that do not natively support image parsing, we use the original images as input, and calculate the ISVGEN score between the rendered output and the original image.
> - [OCRVerse](https://github.com/DocTron-hub/OCRVerse) results are derived from various code formats (e.g., SVG, Python), whereas results for Gemini 3 Pro and dots.ocr-1.5 are based specifically on SVG code.
> - Due to the capacity constraints of a 3B-parameter VLM, dots.ocr-1.5 may not excel in all tasks yet like svg. To complement this, we are simultaneously releasing dots.ocr-1.5-svg. We plan to further address these limitations in future updates.

# Quick Start
## 1. Installation
### Install dots.ocr-1.5
```shell
conda create -n dots_ocr python=3.12
conda activate dots_ocr
git clone https://github.com/rednote-hilab/dots.ocr.git
cd dots.ocr
# Install pytorch, see https://pytorch.org/get-started/previous-versions/ for your cuda version
pip install torch==2.7.0 torchvision==0.22.0 torchaudio==2.7.0 --index-url https://download.pytorch.org/whl/cu128
pip install -e .
```
If you have trouble with the installation, try our [Docker Image](https://hub.docker.com/r/rednotehilab/dots.ocr) for an easier setup, and follow these steps:
```shell
git clone https://github.com/rednote-hilab/dots.ocr.git
cd dots.ocr
pip install -e .
```
### Download Model Weights
> 💡**Note:** Please use a directory name without periods (e.g., `DotsOCR_1_5` instead of `dots.ocr-1.5`) for the model save path. This is a temporary workaround pending our integration with Transformers.
```shell
python3 tools/download_model.py
# with modelscope
python3 tools/download_model.py --type modelscope
```
## 2. Deployment
### vLLM inference
We highly recommend using vLLM for deployment and inference. All of our evaluations results are based on vLLM 0.9.1 via out-of-tree model registration. **Since vLLM version 0.11.0, Dots OCR has been officially integrated into vLLM with verified performance** and you can use vLLM docker image directly (e.g, `vllm/vllm-openai:v0.11.0`) to deploy the model server.
> **Note:**
> - We found a little bit performance drop when using vLLM 0.11.0. We are working on a fix.
```shell
# Launch vLLM model server
## dots.ocr-1.5
CUDA_VISIBLE_DEVICES=0 vllm serve rednote-hilab/dots.ocr-1.5 --tensor-parallel-size 1 --gpu-memory-utilization 0.9 --chat-template-content-format string --served-model-name model --trust-remote-code
## dots.ocr-1.5-svg
CUDA_VISIBLE_DEVICES=0 vllm serve rednote-hilab/dots.ocr-1.5-svg --tensor-parallel-size 1 --gpu-memory-utilization 0.9 --chat-template-content-format string --served-model-name model --trust-remote-code
# vLLM API Demo
# See dots_ocr/model/inference.py for details on parameter and prompt settings
# that help achieve the best output quality.

### Hugginface inference with CPU
Please refer to [CPU inference](https://github.com/rednote-hilab/dots.ocr/issues/1#issuecomment-3148962536)
## 3. Document Parse
**Based on vLLM server**, you can parse an image or a pdf file using the following commands:
```bash
# Parse all layout info, both detection and recognition
# Parse a single image
python3 dots_ocr/parser.py demo/demo_image1.jpg
# Parse a single PDF
python3 dots_ocr/parser.py demo/demo_pdf1.pdf --num_thread 64 # try bigger num_threads for pdf with a large number of pages
# Layout detection only
python3 dots_ocr/parser.py demo/demo_image1.jpg --prompt prompt_layout_only_en
# Parse text only, except Page-header and Page-footer
python3 dots_ocr/parser.py demo/demo_image1.jpg --prompt prompt_ocr
```
**Based on Transformers**, you can parse an image or a pdf file using the same commands above, just add `--use_hf true`.
> Notice: transformers is slower than vllm, if you want to use demo/* with transformers，just add `use_hf=True` in `DotsOCRParser(..,use_hf=True)`
<details>
<summary><b>Output Results</b></summary>
1. **Structured Layout Data** (`demo_image1.json`): A JSON file containing the detected layout elements, including their bounding boxes, categories, and extracted text.
2. **Processed Markdown File** (`demo_image1.md`): A Markdown file generated from the concatenated text of all detected cells.
* An additional version, `demo_image1_nohf.md`, is also provided, which excludes page headers and footers for compatibility with benchmarks like Omnidocbench and olmOCR-bench.
3. **Layout Visualization** (`demo_image1.jpg`): The original image with the detected layout bounding boxes drawn on it.
</details>
## 4. Demo

# Limitation & Future Work
- **Complex Document Elements:**
- **Table&Formula**: The extraction of complex tables and mathematical formulas persists as a difficult task given the model's compact architecture.
- **Picture**: We have adopted an SVG code representation for parsing structured graphics; however, the performance has yet to achieve the desired level of robustness.
- **Parsing Failures:** While we have reduced the rate of parsing failures compared to the previous version, these issues may still occur occasionally. We remain committed to further resolving these edge cases in future updates.
