LiLT FUNSD — GGUF

GGUF conversion of philschmid/lilt-en-funsd for use with CrispEmbed.

LiLT (Language-independent Layout Transformer) is a dual-stream encoder that combines RoBERTa (768d text) with a parallel layout transformer (192d) via BiACM (bidirectional attention complementation). It takes OCR text + bounding boxes and performs token classification for document understanding.

This variant is fine-tuned on FUNSD (Form Understanding in Noisy Scanned Documents) with 7 IOB labels: O, B-HEADER, I-HEADER, B-QUESTION, I-QUESTION, B-ANSWER, I-ANSWER.

Parity

Verified against HuggingFace transformers using the crispembed-diff harness:

• —25/25 encoder stages: cos_min = 1.000000
• —16/16 token labels match (100%)
• —max_abs < 1.6e-03 across all layers
