University of Oxford researchers have created a tool called capAI, a procedure for conducting conformity assessment of AI systems in line with the EU Artificial Intelligence Act. CapAI provides organisations with practical guidance on how to translate high-level ethics principles into verifiable criteria that help shape the design, development, deployment and use of ethical AI. This tool can be used to demonstrate that the development and operation of an AI system are trustworthy. The tool is being validated with firms at the moment and the most up-to-date version can be found here.
