When ChatGPT was launched in November 2022, it captured the imagination of the public as well as leading companies, including the banking sector. But as people explored ChatGPT they soon found flaws. Lawyers and judges realised they had relied on non-existent case law. Others discovered that ChatGPT claimed to be the author of books and articles that existed long before it was created.

Despite these ‘hallucinations’, banks remain attracted by the claim that AI can answer and ask questions, generate text, draft emails and translate natural language to code. Customer relations have in some cases been improved by using this technology, thus cutting costs and improving productivity and profits.

Drawing on original, candid interviews with senior figures in the sector, How AI will revolutionise banking analyses the risks and challenges to banks and their regulators, as well as proposed solutions to issues such as hallucinations. It offers a comprehensive, up-to-date account of this exciting new technology and what it means for the world of finance.
