## What proprietary AI has Citizens built in-house?

Citizens builds AI applications and buys the models. CIO Michael Ruttledge said in September 2024 that 'our plans right now are not to build our own LLM models' and that the bank uses 'best-in-class models from our technology providers'. What it has built on top: a gen-AI portal in which employees choose OpenAI, AWS Bedrock, Anthropic or another provider (December 2025); a gen-AI model for contact-centre product questions that replaced a legacy app (July 2024); CiZi, the AI assistant in the mobile app since November 2024, credited with a 44% cut in mobile-banking calls; LLM voice agents that order debit cards through back-end systems, with 50%-plus of calls to be answered by a non-human over time; an AI lending onboarding platform built by Ruttledge's team; a cloud fraud platform with new detection models; and Digital Butler, a commercial assistant patented in 2024. The 3Q26 deck (October 16, 2026) adds AI phone support built for credit-card calls, AI meeting prep used by about 50% of commercial bankers and analysts, and AI coding tools used by about 95% of engineers. Chief data and analytics officer Krish Swamy said in July 2026 that some models run inside the bank's own VPC. Citizens has not disclosed which model runs CiZi or the voice agents, the size of its AI team or AI spend within its $300 million Reimagine the Bank budget.

## Which AI systems has Citizens built itself?

Systems Citizens describes as its own, oldest first. 'Built on' records what the bank or its vendors have said about the models and platforms underneath.

## Who builds Citizens' in-house AI?

Michael Ruttledge, Chief Information Officer and Head of Enterprise Technology & Security, runs the build: his team built the AI lending onboarding platform, and in July 2024 he described a hackathon that produced more than 90 ideas, narrowed to about half a dozen, with the first two production uses sharing one platform 'rather than having everybody develop' their own. ([American Banker](https://www.americanbanker.com/news/inside-citizens-plan-to-reimagine-itself-with-ai), [Banking Dive](https://www.bankingdive.com/news/citizens-bank-cio-ruttledge-ai-banking-generative-genai/722507/))

Chief data and analytics officer Krish Swamy leads the data side; in July 2026 he described using large language models 'as a translator' that maps what callers say to a small set of things the bank can answer. ([American Banker](https://www.americanbanker.com/leaders/the-ai-enabled-bank-reimagining-retail-banking-from-branch-to-mobile))

Outside capacity comes from Infosys. In April 2026 Ruttledge said 'our AI-first Innovation Hub reflects Citizens' long-term commitment to building modern, secure, and intelligent banking capabilities', built with Infosys and its Topaz Fabric. ([Infosys via PR Newswire](https://prnewswire.com/news-releases/revenue-crosses-20-billion-mark-with-resilient-growth-of-3-1-in-fy-26-in-constant-currency-302751870.html))

The 3Q26 deck counts more than 500 colleagues dedicated to executing Reimagine the Bank, with 35-plus of 50-plus planned initiatives launched and about 95% of software engineers using AI coding tools. Citizens Bank's Deepak Nair presented the voice-agent build with AWS at Customer Contact Week 2026. ([Citizens Financial Group (SEC filing)](https://www.sec.gov/Archives/edgar/data/759944/000075994426000206/a3q26earningspresentatio.htm), [AWS (Amazon Connect)](https://aws.amazon.com/products/connect/customer/resources/customer-contact-week))

## What does Citizens build, and what does it buy?

Models are bought. Ruttledge said in September 2024 that the bank was working with its cloud providers, Amazon Web Services and Microsoft, to deploy large language models, and that 'our plans right now are not to build our own LLM models'. By December 2025 the gen-AI portal offered OpenAI, AWS Bedrock and Anthropic models side by side. ([Bank Automation News](https://bankautomationnews.com/banking/citizens-sees-up-to-20-efficiency-gains-through-gen-ai), [American Banker](https://www.americanbanker.com/news/inside-citizens-plan-to-reimagine-itself-with-ai))

Some hosting is in-house. Swamy said in July 2026 that, with the bank 100% in the cloud, certain models are hosted and run 'within our VPC' so that 'nothing goes out of the VPC', for some use cases but not all, because 'setting up a model instance and running it is also its own kind of engineering task'. ([American Banker](https://www.americanbanker.com/leaders/the-ai-enabled-bank-reimagining-retail-banking-from-branch-to-mobile))

Applications and workflows are built. President Brendan Coughlin said in March 2026 that the bank is 'building all these work streams' for the voice agent, which connects to back-end operations to complete requests rather than only routing calls. ([American Banker](https://www.americanbanker.com/news/citizens-details-how-ai-is-speeding-everything-up))

Vendors are being cut, not added. The 3Q26 deck reports a streamlined process for approving new technology, AI tools and vendors, 35 applications rationalised in 2026 and about 90% of the 2026 vendor savings target reached; on the October 16, 2026 call management said it has 'significant resources dedicated to leveraging AI'. ([Citizens Financial Group (SEC filing)](https://www.sec.gov/Archives/edgar/data/759944/000075994426000206/a3q26earningspresentatio.htm), [The Motley Fool](https://fool.com/earnings/call-transcripts/2026/10/16/citizens-cfg-q3-2026-earnings-call-transcript))

## What has Citizens not disclosed about its in-house AI?

Citizens' own materials do not name the model behind CiZi or the LLM voice agents, the number of employees using the gen-AI portal, or which models are hosted inside its VPC. ([Citizens](https://citizensbank.com/mobile-and-online-banking/cizi.aspx), [American Banker](https://www.americanbanker.com/leaders/the-ai-enabled-bank-reimagining-retail-banking-from-branch-to-mobile))

No AI engineering headcount or AI-only budget is published; the AI work is funded inside Reimagine the Bank, a three-year, $300 million program targeting at least $450 million of pre-tax run-rate benefit by year-end 2028. The Digital Butler patent was reported by Bank Automation News without a patent number. ([American Banker](https://www.americanbanker.com/news/citizens-details-how-ai-is-speeding-everything-up), [Citizens Financial Group (SEC filing)](https://www.sec.gov/Archives/edgar/data/759944/000075994426000206/a3q26earningspresentatio.htm), [Bank Automation News](https://bankautomationnews.com/allposts/ai/citizens-receives-patent-for-its-digital-butler))

## Common questions

### Does Citizens build its own AI models?

Not large language models. CIO Michael Ruttledge said in September 2024 that 'our plans right now are not to build our own LLM models' and that Citizens uses 'best-in-class models from our technology providers'. It does build its own applications, agents and some machine-learning models, such as new fraud-detection models, and hosts certain models inside its own VPC.

### What AI has Citizens built in-house?

A gen-AI portal for employees, a contact-centre product model (2024), the CiZi app assistant (November 2024), the Digital Butler commercial assistant (patented 2024), a cloud fraud platform with new detection models, an AI lending onboarding platform, agentic complaint handling, LLM voice agents, an enterprise AI-chat agent and AI phone support for credit-card calls (October 2026).

### Which AI models does Citizens use?

Its gen-AI portal lets employees choose OpenAI, AWS Bedrock, Anthropic or another LLM provider, per American Banker in December 2025. In 2024 the CIO named AWS and Microsoft as the providers it works with to deploy large language models. The bank has not named the model behind CiZi or its voice agents in its own materials.

### What is Citizens' gen-AI portal?

An internal gateway where Citizens employees pick among OpenAI, AWS Bedrock, Anthropic and other LLM providers. Ruttledge said it gives the bank 'the freedom to adopt different ones where we think someone's got a leap on the market and we want to get there'. Usage figures for the portal have not been published.

### How much of Citizens' call volume will its AI agents handle?

President Brendan Coughlin said in March 2026 that the goal is for 50%-plus of phone calls to be answered by a non-human, with the bank halfway there by the end of 2026. The agents can reorder a debit card, start a fraud claim or read recent transactions, and AWS says in-app voice agents took adoption from 0% to about 60%.
