Ursula von der Leyen, president of the European Commission, and Vera Jourova, a vice president, will attend the summit, according to an update to their official calendars published on Friday.
While Sunak hopes to secure Britain's role as a world leader in AI regulation, some have questioned what the summit will achieve in practice.
Last week, Bloomberg reported a number of world leaders - including Germany's Olaf Scholz and Canada's Justin Trudeau - would not be attending.
While several world leaders, including U.S. Vice President Kamala Harris, are expected to attend the summit, the full guest list has not been made public.
Matt Clifford, a tech investor and one of two chief organisers of the event, recently told Reuters the aim of the summit was to kickstart international dialogue on AI regulation.
