The Hong Kong Monetary Authority (HKMA), together with Hong Kong Cyberport Management Company Limited (Cyberport), co-hosted a Generative Artificial Intelligence (GenA.I.) Symposium, marking the conclusion of the first cohort of the GenA.I. Sandbox and the commencement of the second cohort. The HKMA also published the Report on the First Cohort of the GenA.I. Sandbox and unveiled a pilot GenA.I. chatbot intended to provide more interactive access to the Sandbox’s insights and practical guidance. The report highlights GenA.I.’s potential to add value in banking, particularly in enhancing risk management, anti-fraud capabilities and customer experience. It also shares technical learnings from trials conducted at Cyberport’s Artificial Intelligence Supercomputing Centre, including practical guidance on model fine-tuning and guardrail implementation for safer and domain-specific solutions. The pilot chatbot tests the feasibility of a knowledge-bound GenA.I. approach designed to address concerns such as hallucinations and inaccuracies; Amazon Web Services showcased the chatbot developed in collaboration with the HKMA. The symposium drew over 500 practitioners from banking, insurance and technology sectors and included participant showcases and panel discussions on GenA.I. developments and implications for the financial sector. The HKMA linked insights from the first cohort to the initiation of Project Noor, a collaboration with the Bank for International Settlements Innovation Hub (BISIH) and other regulators aimed at developing an explainable A.I. toolkit.
