Introduction

We present dots.mocr. Beyond achieving state-of-the-art (SOTA) performance in standard multilingual document parsing among models of comparable size, dots.mocr excels at converting structured graphics (e.g., charts, UI layouts, scientific figures and etc.) directly into SVG code. Its core capabilities encompass grounding, recognition, semantic understanding, and interactive dialogue.

Simultaneously, we are releasing dots.mocr-svg, a variant specifically optimized for robust image-to-SVG parsing tasks.

More information can be found in the paper.

Notes:

Results for Gemini 3 Pro, PaddleOCR-VL-1.5, and GLM-OCR were obtained via APIs, while HuanyuanOCR results were generated using local inference.

The Elo score evaluation was conducted using Gemini 3 Flash. The prompt can be found at: Elo Score Prompt. These results are consistent with the findings on ocrarena.

Note:

Metrics are sourced from OmniDocBench and other model publications. pdf-parse-bench results are reproduced by Qwen3-VL-235B-A22B-Instruct.

Formula and Table metrics for OmniDocBench1.5 are omitted due to their high sensitivity to detection and matching protocols.

2. Structured Graphics Parsing

Visual languages (e.g., charts, graphics, chemical formulas, logos) encapsulate dense human knowledge. dots.mocr unifies the interpretation of these elements by parsing them directly into SVG code.

Methods	Unisvg	Chartmimic	Design2Code	Genexam	SciGen	ChemDraw
Low-Level	High-Level	Score
OCRVerse	0.632	0.852	0.763	0.799	-	-	-	0.881
Gemini 3 Pro	0.563	0.850	0.735	0.788	0.760	0.756	0.783	0.839
dots.mocr	0.850	0.923	0.894	0.772	0.801	0.664	0.660	0.790
dots.mocr-svg	0.860	0.931	0.902	0.905	0.834	0.8	0.797	0.901

Note:

We use the ISVGEN metric from UniSVG 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 results are derived from various code formats (e.g., SVG, Python), whereas results for Gemini 3 Pro and dots.mocr are based specifically on SVG code.

Due to the capacity constraints of a 3B-parameter VLM, dots.mocr may not excel in all tasks yet like svg. To complement this, we are simultaneously releasing dots.mocr-svg. We plan to further address these limitations in future updates.

Quick Start

1. Installation

Install dots.mocr

shell

conda create -n dots_mocr python=3.12
conda activate dots_mocr

git clone https://github.com/rednote-hilab/dots.mocr.git
cd dots.mocr

# 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
# install flash-attn==2.8.0.post2 for faster inference
pip install -e .

If you have trouble with the installation, try our Docker Image for an easier setup, and follow these steps:

Download Model Weights

💡Note: Please use a directory name without periods (e.g., DotsMOCR instead of dots.mocr) 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. 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.

shell

# Launch vLLM model server
## dots.mocr
CUDA_VISIBLE_DEVICES=0 vllm serve rednote-hilab/dots.mocr --tensor-parallel-size 1 --gpu-memory-utilization 0.9 --chat-template-content-format string --served-model-name model --trust-remote-code

## dots.mocr-svg
CUDA_VISIBLE_DEVICES=0 vllm serve rednote-hilab/dots.mocr-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

# that help achieve the best output quality.

    - All layout elements must be sorted according to human reading order.

5. Final Output: The entire output must be a single JSON object.

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_mocr/parser.py demo/demo_image1.jpg
# Parse a single PDF
python3 dots_mocr/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_mocr/parser.py demo/demo_image1.jpg --prompt prompt_layout_only_en

# Parse text only, except Page-header and Page-footer
python3 dots_mocr/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 DotsMOCRParser(..,use_hf=True)

Output Results

Structured Layout Data (demo_image1.json): A JSON file containing the detected layout elements, including their bounding boxes, categories, and extracted text.
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.
Layout Visualization (demo_image1.jpg): The original image with the detected layout bounding boxes drawn on it.

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.
