dots.ocr

1. Powerful Performance: dots.ocr achieves SOTA performance for text, tables, and reading order on OmniDocBench, while delivering formula recognition results comparable to much larger models like Doubao-1.5 and gemini2.5-pro.
2. Multilingual Support: dots.ocr demonstrates robust parsing capabilities for low-resource languages, achieving decisive advantages across both layout detection and content recognition on our in-house multilingual documents benchmark.
3. Unified and Simple Architecture: By leveraging a single vision-language model, dots.ocr offers a significantly more streamlined architecture than conventional methods that rely on complex, multi-model pipelines. Switching between tasks is accomplished simply by altering the input prompt, proving that a VLM can achieve competitive detection results compared to traditional detection models like DocLayout-YOLO.
4. Efficient and Fast Performance: Built upon a compact 1.7B LLM, dots.ocr provides faster inference speeds than many other high-performing models based on larger foundations.

Usage with transformers

from transformers import AutoModelForCausalLM, AutoProcessor, AutoTokenizer
from qwen_vl_utils import process_vision_info
from dots_ocr.utils import dict_promptmode_to_prompt

model_path = "./weights/DotsOCR"

image_path = "demo/demo_image1.jpg"
prompt = """Please output the layout information from the PDF image, including each layout element's bbox, its category, and the corresponding text content within the bbox.

1. Bbox format: [x1, y1, x2, y2]

2. Layout Categories: The possible categories are ['Caption', 'Footnote', 'Formula', 'List-item', 'Page-footer', 'Page-header', 'Picture', 'Section-header', 'Table', 'Text', 'Title'].

3. Text Extraction & Formatting Rules:
    - Picture: For the 'Picture' category, the text field should be omitted.
    - Formula: Format its text as LaTeX.
    - Table: Format its text as HTML.
    - All Others (Text, Title, etc.): Format their text as Markdown.

4. Constraints:
    - The output text must be the original text from the image, with no translation.
    - All layout elements must be sorted according to human reading order.

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

Performance Comparison: dots.ocr vs. Competing Models

Notes:

• The EN, ZH metrics are the end2end evaluation results of OmniDocBench, and Multilingual metric is the end2end evaluation results of dots.ocr-bench.

News

• 2025.07.30 🚀 We release dots.ocr, — a multilingual documents parsing model based on 1.7b llm, with SOTA performance.

Benchmark Results

1. OmniDocBench

The end-to-end evaluation results of different tasks.

The end-to-end text recognition performance across 9 PDF page types.

Notes:

• The metrics are from MonkeyOCR, OmniDocBench, and our own internal evaluations.
• We delete the Page-header and Page-footer cells in the result markdown.
• We use tikz_preprocess pipeline to upsample the images to dpi 200.

2. dots.ocr-bench

This is an inhouse benchmark which contain 1493 pdf images with 100 languages.

The end-to-end evaluation results of different tasks.

Notes:

• We use the same metric calculation pipeline of OmniDocBench.
• We delete the Page-header and Page-footer cells in the result markdown.

Layout Detection

Notes:

• prompt_layout_all_en for parse all, prompt_layout_only_en for detection only, please refer to prompts

3. olmOCR-bench.

Note:

• The metrics are from MonkeyOCR, olmocr, and our own internal evaluations.
• We delete the Page-header and Page-footer cells in the result markdown.
