In an experimental customer-service use case, Santander improved conversation quality while reducing costs by more than 50%.
Santander establishes a three-year framework for the next phase of collaboration with NVIDIA.
Madrid and Santa Clara (California), October 19, 2026.
Banco Santander today announced a new milestone in their artificial intelligence collaboration with NVIDIA. With support from NVIDIA, the Santander AI Lab has developed new capabilities to evaluate AI models and agents for banking applications, helping identify which model is best suited for each task and deploy it in the most efficient way.
The work is being carried out through Santander AI Lab, which explores and tests emerging AI technologies before broader deployment across the bank. As part of this effort, Santander has been progressively moving from large general-purpose models towards smaller, specialised models designed for specific banking tasks. In selected experimental use cases, this approach has reduced serving costs from around €5 per interaction to approximately €0.03 while maintaining strong performance.
Through the Lab, Santander has built Model Arena to evaluate open-weight models against banking tasks and identify the right model for each workload, and is specialising models using NVIDIA NeMo Customizer. Customer-service comparisons delivered evidence that smaller, specialised models can deliver strong performance on targeted banking tasks. Santander has built…
