Nubank Partners with OpenAI to Enhance Efficiency

Brazilian digital bank Nubank has formed a partnership with ChatGPT developer OpenAI to enhance both customer interactions and internal operations, according to a statement from OpenAI.

One of the key innovations emerging from this collaboration is a customised enterprise search engine. Utilising Retrieval-Augmented Generation (RAG) techniques, this tool enables Nubank’s workforce of over 7,000 employees to efficiently access internal data, facilitating improved decision-making and streamlined workflows.

Additionally, the partnership has resulted in the development of a Call Centre Copilot, designed to assist customer service agents in real time. By integrating the bank’s chat history and knowledge base, the tool provides next-reply suggestions, chat summarisation, technical guidance, and other supportive functions.

Nubank has also introduced an AI-powered assistant, leveraging the capabilities of OpenAI’s multimodal large language model GPT-4o, to respond directly to customer inquiries.

Beyond customer support enhancements, Nubank is piloting a GPT-4o vision-powered solution aimed at ensuring more consistent and high-quality responses to fraud incidents. This advanced technology combines natural language processing with image recognition to analyse customer communications, transaction records, and submitted documents.

With this initiative, Nubank joins a growing number of financial institutions worldwide that are adopting OpenAI’s solutions, including BNY Mellon and BBVA.
