SmolDocling: A New Era in Document Processing — OCR

A model that outperforms its competitors 27 times its size with the DocTags format

Document understanding and conversion technologies have become one of the most critical components of digitalization processes today. SmolDocling, a new development in this field, stands out as an ultra-compact vision model designed for end-to-end document conversion.

The paper of this model, prepared jointly by HuggingFace and IBM, was published on March 14. If you are ready now, we will examine what is written in this paper and how it is implemented.

What is SmolDocling?

SmolDocling is an ultra-compact model derived from Hugging Face’s SmolVLM-256M model, 5–10 times smaller than other vision models. Containing only 256 million parameters, this model performs at a level that can compete successfully with vision models 27 times larger.
