AI Deployment Transforms Productivity at Scale
Citigroup has achieved a major milestone in its ongoing IT modernization: the deployment of
Citi Squad, a generative AI coding assistant, is now freeing up approximately
100,000 hours of developer time every week as of late 2025. This marks a sharp acceleration in productivity for the bank’s roughly 40,000 global developers, reflecting Citi’s multi-year strategy to deeply integrate artificial intelligence into both technology operations and daily workflows.
How Citi’s AI Tools Deliver Impact
Citi’s comprehensive approach centers on democratizing AI access across its organization—not only for developers, but for employees in diverse roles. Key elements of the bank’s strategy include:
-
Citi Squad: A generative AI coding assistant purpose-built for Citi’s software engineers. This tool has already completed more than 220,000 automated code reviews in a single quarter, dramatically speeding up development and improving code quality[1][8].
-
Citi Stylus: A document intelligence platform that allows staff to summarize, analyze, and compare documents in real-time—streamlining workflows in departments such as legal, compliance, and audit[8].
-
Citi Assist: An advanced virtual assistant embedded in Microsoft Teams, designed to guide employees through complex internal policies and procedures, facilitating faster access to knowledge across HR, risk, and finance[8].
AI-Native Workforce and Modern Infrastructure
These AI deployments are part of a broader overhaul involving the migration to modern, unified cloud platforms and the cultivation of an AI-native workforce. By consolidating fragmented tech stacks and retiring over 2,000 legacy applications in the past three years alone, Citi ensures that advanced tools like
Citi Squad operate on a robust digital foundation[1][8].
The roll-out is supported by “AI accelerators”—enthusiastic employees who champion adoption within departments—and a leadership commitment to embedding AI throughout everyday operations[2][8]. Citi’s approach emphasizes both top-down vision and bottom-up empowerment to maximize impact.
Gains Beyond Citigroup: Banking Industry Adopts Generative AI
The productivity leap at Citi mirrors broader trends in the financial sector. Banks worldwide are equipping software engineers with generative AI assistants: similar initiatives at competitors like JPMorgan Chase have yielded developer productivity increases of up to 20%, with forecasts of 20–40% software ROI improvements across the industry by 2028[5][7].
The Road Ahead
With 100,000 developer hours freed each week and over 385,000 staff interactions logged across its suite of AI tools, Citi is positioning itself at the forefront of enterprise AI adoption[1][8]. The bank’s ongoing investments, totaling $2.4 billion in technology and communications for the first quarter of 2025 alone, signal that generative AI will remain central to Citi’s operational and competitive strategy going forward[1].
