In the absence of congressional action on comprehensive artificial intelligence (AI) legislation, state legislatures are forging ahead with groundbreaking bills to regulate the rapidly advancing technology. On May 8, the Colorado House of Representatives passed SB 205, a far-reaching and comprehensive AI bill, on a 41-22-2 vote. The final vote comes just days after the state Senate’s passage of the bill on May 3, making Colorado the first state in the nation to send comprehensive AI legislation to its governor for signing. While Governor Jared Polis (D) has not indicated whether he will sign or veto the bill, if SB 205 becomes law, it would establish a broad regulatory regime for developers and deployers of “high-risk” AI systems.
