Madrid – October 31, 2026 -- Banco Santander cut costs by more than 50% in an experimental customer-service use case while improving conversation quality, and has now signed a three-year AI collaboration framework with NVIDIA.
Smaller models cut serving costs from €5 to €0.03 per interaction
Santander AI Lab has moved progressively from large general-purpose models to smaller, specialised models built for specific banking tasks. In selected experimental use cases, serving costs fell from around €5 per interaction to approximately €0.03, with performance maintained.
The Lab runs inference within Santander's own architecture on NVIDIA Dynamo-Triton, the approach behind the serving-cost reduction.
