Illinois AI Safety Bill SB 315: Frontier AI Developers Compliance by 2028

Illinois SB 315 targets frontier AI developers, requiring them to complete mandatory safety measures by January 2028, including risk identification, model testing, and consumer disclosure. 'Frontier AI' typically refers to general or generative AI systems exceeding thresholds in model scale, capability, or training compute. Non-compliance may lead to fines or business restrictions. The bill directly impacts model developers offering AI products in Illinois, enterprises deploying large models, and teams with training compute above standard thresholds. These organizations must establish safety testing and reporting processes in advance, ensuring products pass compliance review before the law takes effect. For small and medium teams, compliance costs could become a new entry barrier, while large firms need to adjust previously relaxed testing schedules.
