What is the Illinois AI Safety Measures Act (SB 315)?
Illinois's frontier-AI safety and transparency law, built on the model of California SB 53: large frontier developers must publish a frontier AI framework and update it every year, publish a transparency report when they deploy a new or substantially modified frontier model, report critical safety incidents to the Illinois Emergency Management Agency and Office of Homeland Security, and protect whistleblowing employees. Unlike the California and New York laws, it also requires annual independent third-party audits, with a published summary.

Who does it apply to?
A "frontier model" is a foundation model trained with more than 10^26 operations, counting fine-tuning and other material modifications; a "large frontier developer" also had more than $500 million in annual gross revenue in the prior year, with affiliates. Ordinary deployers of AI systems are not covered.

Frequently asked questions
Which US states have frontier AI safety and transparency laws?
Three states have enacted laws requiring large frontier-model developers to publish safety frameworks and report critical incidents: California (SB 53, the Transparency in Frontier Artificial Intelligence Act), New York (the RAISE Act) and Illinois (SB 315, the AI Safety Measures Act), which also requires annual third-party audits. Connecticut's SB 5 covers large frontier developers through whistleblower and internal-reporting duties rather than published frameworks.
How does the Illinois AI Safety Measures Act differ from California SB 53?
Both apply to large frontier developers above the same compute and revenue thresholds and require a published frontier AI framework, transparency reports, incident reporting and whistleblower protection.
