Regulatory cooperation in AI sandboxes: insights from Fintech

With the expansion of artificial intelligence worldwide, countries have started adopting the sandbox regime commonly used in the financial sector to examine AI applications in various domains and contexts. The European Union has gone even further, with its new Artificial Intelligence Act obliging EU Member States to establish AI sandboxes. This article proposes an optimal model for regulatory cooperation in AI sandboxes at the national level. Drawing on the experience of Fintech sandboxes, including the Digital Securities Sandbox in the United Kingdom, the article examines various potential models for operating regulatory sandboxes in the field of AI: jointly administered cross-sector sandboxes, separate sandboxes with a single-entry mechanism, and separate sandboxes with independent entry points. Additionally, the article evaluates the mechanism of a joint regulatory committee, whether as a statutory body with decision-making power or as a coordinating committee based on soft law instruments such as memoranda of understanding.
