## Summary

Santander announced a partnership with Nvidia to create a suite of AI tools for banking, focusing on evaluating and deploying the most suitable models for each task. The bank’s AI lab has built a “Model Arena” that pits open‑weight models against real banking workloads and uses Nvidia’s NeMo Customizer to fine‑tune smaller, task‑specific models. In internal tests the new approach cut serving costs from €5 per interaction to roughly €0.03 while maintaining strong performance.

A pilot customer‑service use case showed that the specialized model improved conversation quality and reduced costs by more than 50%, according to the release. Santander said the collaboration will expand to foundation models, AI agents, fraud and anti‑money‑laundering tools, real‑time decisioning and digital‑twin simulations. Nvidia’s global banking lead, Aser Blanco, emphasized that cost per intelligence output is a key metric for data‑heavy banks and that Santander is demonstrating production‑scale efficiency with smaller, data‑focused models. Recent PYMNTS Intelligence research found 95% of large financial‑services firms have broadly deployed AI tools, though only 25% have adopted AI in API orchestration and integration.

## Key points

- Santander cut AI serving costs from €5 per interaction to about €0.03 using smaller specialized models.
- The bank’s Model Arena evaluates open‑weight models for banking tasks, leveraging Nvidia’s NeMo Customizer.
- A customer‑service test improved conversation quality while lowering costs by more than 50%, per the release.

## Why it matters

Shows how banks can dramatically lower AI operating costs and boost performance, encouraging broader AI adoption in finance and shaping vendor collaborations.
