Model overview

dots.ocr is a multilingual document parsing model that combines layout detection and content recognition into a single vision-language architecture. Built on a compact 1.7B parameter foundation, this model achieves state-of-the-art performance across text recognition, table extraction, and reading order tasks while maintaining faster inference speeds than larger competing models. Unlike traditional multi-model pipelines that require separate tools for different document elements, this unified approach handles diverse document types through simple prompt adjustments. The model demonstrates particular strength in multilingual scenarios and low-resource languages, setting it apart from simpler OCR solutions like text-extract-ocr or basic ocr-pdf tools. Developed by sljeff, the model represents a significant advancement in document understanding technology.

Model inputs and outputs

The model accepts image inputs and generates structured JSON output containing layout information with bounding boxes, categories, and extracted content. Users can customize the extraction behavior through prompt engineering and control generation parameters for optimal results.

Inputs

image: Input document image in URI format for OCR processing
prompt: Customizable instruction text that guides the extraction process and output format
max_tokens: Maximum token limit for generation (1-32768, default 16384)
temperature: Sampling temperature controlling randomness (0-2, default 0.1)
top_p: Top-p sampling parameter for nucleus sampling (0-1, default 1)
