The Hong Kong Monetary Authority, working with the Hong Kong Cyberport Management Company Limited, has announced the second cohort of the Generative Artificial Intelligence (GenA.I.) Sandbox, selecting 27 use cases from 20 banks and 14 technology partners from more than 60 proposals. The cohort is positioned as a move from experimentation toward secure and reliable implementation of generative AI in banking. Selected submissions were prioritised based on innovation, technical complexity and potential industry value. The use cases include governance-oriented “AI vs AI” approaches, such as using AI to run automated quality checks on AI-generated outputs, and deepfake-fraud defence testing, including adversarial simulations to stress-test and strengthen systems against sophisticated digital fraud. Participants will gradually onboard to the designated platform at Cyberport’s Artificial Intelligence Supercomputing Centre later in 2025, with trials commencing in early 2026. The HKMA plans to use the GenA.I. Sandbox to share good practices and promote responsible AI adoption in the financial sector.
