How does generative AI affect real workplace productivity? This column reports results from an experiment at the National Bank of Slovakia, where staff were randomly assigned GPT-4o access while completing routine and non-routine tasks. The model improved output quality by up to 44% and cut completion time by 21%, with the largest gains on non-routine, domain-specific work. Lower-skill staff saw the biggest quality boosts, while higher-skill colleagues saved the most time. The findings highlight how task characteristics and human capital shape the returns to AI, suggesting that productivity gains will depend not just on adoption, but on how organisations redesign work and reallocate tasks.
