Knowledgator has introduced GLiFormer Large, a 575-million-parameter encoder model designed for structured document extraction tasks. It achieves a 91.10 F1 score on nested JSON extraction, placing it close to GPT-5.6-luna's 91.96 on the same benchmark.
Unlike generative LLMs that produce tokens autoregressively, GLiFormer operates as an encoder. This means it identifies and classifies spans within source text directly, assigning each extracted value to its exact location in the original document rather than generating new text.
The span-grounding approach matters for enterprise data pipelines where traceability is critical. By tying every output field back to a specific source span, the model reduces hallucination risk and makes it easier to audit extracted structured data against original inputs.
At 575 million parameters, GLiFormer reaches near-frontier performance on this specific task at a fraction of the size of large generative models. This could lower compute costs for document-processing workloads such as parsing invoices, contracts, and forms into nested JSON structures.
