AI coding assistants and software-maintenance agents
Citi reported 740,000 automated reviews as it added Devin to its developer tools
Problem
Developers spent time reviewing code and performing routine software maintenance.
Approach
Citi began deploying GitHub Copilot around 2024 and launched its Citi Squad developer tool that year. In July 2025, it had started using Cognition's Devin for tasks such as library upgrades. Devin examined repositories and tested proposed changes before presenting them for human review and approval.
Results
Takeaway
Citi introduced autonomous maintenance tasks alongside coding assistance while retaining human approval of changes. The review count was the bank's estimate.
