Bank of America will invest $4 billion in AI and related technology innovations this year, but the financial services giant’s 7-year-old homemade AI agent, Erica, remains a key ROI generator, linchpin for customer and employee experience, and source of great pride today. Few used the term agent, let alone agentic AI, in 2018, but the bank built a team of software engineers, linguistic specialists, and banking experts to create the small language model, which has been tuned over the years using customer feedback data from the call center. Hari Gopalkrishnan, head of consumer, business, and wealth management technology at BofA, says the key to Erica’s success and longevity has been its small size. “We are not writing essays with Erica. We are not trying to write software. We’re trying to understand short bursts of information a customer asks us because they don’t want to hunt and peck on a menu on a screen that’s got 50 different things, and basically be able to translate, what does the customer really mean when they say, ‘I want to pay a bill’?” Gopalkrishnan says. “How do we understand the short burst of conversation that the customer would want? “We trained the model to do just that,” he says about Erica, which is built on open-source models. “Over time, it went from a model that was 80% accurate to 85% to well in the north of 90% accurate. It also let us be more predictive in what the model would do.” Gopalkrishnan says the Bank of America was able to tune Erica during the pandemic to enable customers to apply for PPP loans and handle a multitude of business and consumer needs. He will embrace generative AI and agentic AI offerings as they evolve but believes that most of the bank’s customers requirements can be built in house. |
