While VLMs are improving quickly, there are not good enough to handle a variety of documents with complex visual elements in one shot. Document ingestion requires a hiearchical, modular approach that breaks the problem into a multiple stages, which ideally should be customized for your specific needs. Image The library offers a pre-built modules, such as `LayoutParser`, `DocumentReader` and `Formatter` that can be used to build custom pipelines. It comes with a few off-the-shelf models for layout detection and OCR, and also encourages bring in custom finetuned models to support special needs.
