Banks have long used traditional AI and machine learning techniques for various functions, such as customer service bots and decision algorithms that provide a faster-than-human response to market swings. But modern generative AI is different from prior AI/ML methods, and it has its own strengths and weaknesses. Hari Gopalkrishnan, Bank of America’s chief information officer and head of retail, preferred, small business, and wealth technology, said generative AI is a new tool that offers new capabilities, rather than a replacement for prior AI efforts. “We have a four-layer framework that we think about with regards to AI,” Gopalkrishnan told. The first layer is rules-based automation that takes actions based on specific conditions, like collecting and preserving data about a declined credit card transaction when one occurs. The second is analytical models, such as those used for fraud detection. The third layer is language classification, which Bank of America used to build Erica, a virtual financial assistant, in 2016. “Our journey of Erica started off with understanding language for the purposes of classification,” Gopalkrishnan said. But the company isn’t generating anything with Erica, he added: “We’re classifying customer questions into buckets of intents and using those intents to take customers to the right part of the app or website to help them serve themselves.” The fourth layer, of course, is generative AI. Given the history, it’d be reasonable to think banks would turn generative-AI tools into new chatbots that more or less serve as better versions of Bank of America’s Erica, or as autonomous financial advisors. But the most immediate changes instead came to internal processes and tools. Bank of America is pursuing similar applications, including a call center tool that saves customer associates’ time by transcribing customer conversations in real time, classifying the customer’s needs, and generating a summary for the agent. The decision to deploy generative AI internally first, rather than externally, was in part due to generative AI’s most notable weakness: hallucinations. Banks are wary of consumer-facing AI chatbots that could make similar errors about bank products and policies. Deploying generative AI internally lessens the concern. It’s not used to autonomously serve a bank’s customers and clients but to assist bank employees, who have the option to accept or reject its advice or assistance. Bank of America provides AI tools that can help relationship bankers prep.
