Research reveals that open-source large models commonly exhibit list-filling phenomena in structured extraction.

An empirical study published on October 24, 2026, on arXiv (paper ID 2610.30997v1) found that when a JSON extraction schema specifies a minimum number of items in the list but the actual document content falls short, eight open-source weighting models generally treat this minimum value as a generation target rather than a constraint, resulting in 55.4% of output lists exceeding the true count (compared to a baseline of 34.5%). The filler items are often drawn from the original text, and about half pass the source‑consistency check; common mitigation strategies prove only marginally effective.

Why it matters：This study employed a preregistered protocol to systematically evaluate eight open-source models and six hosted-service models across 558 real-world documents and nine annotated datasets. With a rigorous methodology and publicly available data—both the code and results have been released on GitHub—it reveals a critical yet often overlooked deficiency in structured information extraction that undermines the reliability of downstream tasks: schema‑induced non‑faithful filling behavior.

Several leading financial institutions in Europe have adopted open-source large models to build proprietary intelligent systems.

At the GTC Berlin conference, European financial institutions including Revolut, Starling Bank, Lloyds, and Santander announced that they are building production‑grade AI capabilities based on NVIDIA’s accelerated computing platform and open‑source weight models—such as PRAGMA, the Nemotron series, and the Kumo family—covering core use cases like trading analytics, speech recognition, fraud detection, and data pipeline acceleration, while emphasizing data sovereignty, cost control, and compliant deployment.

NVIDIA’s open-source models are helping to bring AI projects in the public sector to fruition across multiple European countries.

NVIDIA, in collaboration with governments and technology partners across multiple European countries, is advancing sovereign, controllable AI applications—leveraging open-source large models such as Nemotron and synthetic persona datasets—in Germany, Poland, the United Kingdom, France, Greece, and other nations. These efforts span areas including medical image analysis, employment services, digital government assistants, classified information processing, and localized language modeling.
