  • Building docling-server: a one-command document API for our AI pipeline
    If you have not seen docling yet, it is IBM's document processing library. PDF, DOCX, PPTX, scanned images, tables, the whole lot โ€” out comes structured output. Very good at its job. The problem is not docling. The problem is everything around it. - Source: dev.to / 4 months ago
  • The Curse of Context Window
    OCR was the obvious option and with so many opensource libraries available, we were spoilt for choices. I Wanted to use Docling as my prior experience with it has been good so Far (I shall write a separate blog on those use-cases) but we were constrained by the infra. - Source: dev.to / 6 months ago
  • ๐Ÿ“ฃ Just announced: IBM Granite-Docling: End-to-end document understanding with one tiny model
    Granite Docling is a multimodal Image-Text-to-Text model engineered for efficient document conversion. It preserves the core features of Docling while maintaining seamless integration with DoclingDocuments to ensure full compatibility. - Source: dev.to / 11 months ago
  • So you want to parse a PDF?
    Docling* works pretty well in PDF hell, but is terribly slow. *https://docling-project.github.io/docling/. - Source: Hacker News / about 1 year ago
