- AI contributes 40% to code releases, significantly boosting productivity.
- Digital banking product releases increased over 200-fold since a decade ago.
- Bank operates with 20% fewer employees despite doubling in size.

Fifth Third Bancorp has reported significant cost savings attributed to its strategic implementation of artificial intelligence. Chief Executive Officer Tim Spence highlighted that AI tools, introduced about two years ago, have become integral to the bank's operations.
Currently, AI is responsible for 40% of the code released by the company. This increased productivity has facilitated a massive expansion in digital offerings, with mobile app releases jumping from two to three annually a decade ago to over 400 in 2025.
Spence also noted that the bank's workforce has decreased by 20% over the past ten years, despite its assets nearly doubling following the recent acquisition of Comerica Inc. The successful integration of AI alongside traditional automation has allowed for greater operational efficiency.
