Form parsing challenges for vision-language models
LlamaIndex argues that forms need purpose-built parsing to preserve section structure, match values to the right boxes and handle handwriting and checkmarks.
TLDR
LlamaIndex says frontier vision-language models struggle to parse W-2s, 1040s, W-9s and scanned W-4s. Its blog argues that parsing must identify every field, preserve the hierarchy of sections and fields, and link each value to its box. It also describes a custom LlamaParse cookbook that the company says can handle the forms at a fraction of the cost.
