On Friday, David Sacks, former White House AI and crypto czar and current co-chair of the President’s Council of Advisors on Science and Technology, defended open-source artificial intelligence models.
He cited legal-tech startup Harvey’s new Tenet model as evidence of American innovation built on open systems.
Sacks Warns Against Restrictions
In a post on X, Sacks said Harvey’s approach shows how "American companies are building world-class specialized models."
He noted that the startup used the open-source Kimi K3 as a base and trained it on legal data, achieving top-tier results on legal benchmarks at a fraction of the cost of proprietary "frontier" models.
