Illinois Passes Frontier AI Safety Bill SB 315

Illinois lawmakers passed Senate Bill 315 on May 29, 2026, establishing a new accountability measure for powerful AI models ^[1][3]. The bill focuses on transparency for "frontier" AI systems to prevent catastrophic risks before public deployment ^[1]. It targets companies that possess massive computing power or significant annual revenue ^[1][2].

Under the new law, AI developers must undergo annual third-party audits to verify safety standards ^[1][3]. Companies are also required to publish transparency frameworks detailing their efforts to mitigate potential harms ^[2]. This move follows similar legislative efforts in states like Connecticut and New York to regulate emerging technology ^[2].
