Docling Layout Heron (GGUF for LM-Kit)
A GGUF conversion of docling-project/docling-layout-heron, an RT-DETRv2 document layout detector. It finds the regions of a page with their bounds and confidence, across 17 classes: caption, footnote, formula, list item, page footer, page header, picture, section header, table, text, title, document index, code, checkbox (selected and unselected), form and key-value region.
This file runs on LM-Kit.NET's graph runner (architecture lmkit-layout-rtdetr), on the CPU or a GPU, in full F32 precision. It is not a llama.cpp language model.
