Nubank Partners with OpenAI to Enhance Customer Experience

Nubank has partnered with OpenAI to enhance customer experience and internal efficiency, leveraging AI solutions such as GPT-4o. The collaboration aims to optimize services for Nubank's 114 million customers across Brazil, Mexico, and Colombia.

Initially, Nubank worked with OpenAI to develop a custom enterprise search tool, which provides employees with quick access to FAQs, brand guidelines, and internal policies. This tool, powered by GPT-4o and GPT-4o mini, uses Retrieval-Augmented Generation (RAG) techniques to deliver accurate answers, improving productivity and onboarding processes for over 5,000 employees monthly.

Building on this foundation, Nubank has introduced a call center copilot to assist human agents with conversation summaries and recommended answers. Additionally, an AI Assistant powered by GPT-4o manages up to five automated interactions before escalating, handling over two million chats monthly. These tools have enabled Nubank to resolve queries 2.3 times faster with higher accuracy.

Furthermore, Nubank is piloting the use of GPT-4o to tackle fraud by analyzing transaction records, customer communications, and submitted documents to identify potential fraud patterns and anomalies.
