Governor JB Pritzker signed artificial intelligence legislation modeled after similar bills in California and New York on Monday, furthering a push for a state-driven national framework in lieu of federal regulations.
Senate Bill 315, also known as the Artificial Intelligence Safety Measures Act, increases transparency and accountability requirements for the largest artificial intelligence models — those that generate more than $500 million in annual revenue and are trained using massive computing power.
The bill mirrors legislation in California and New York, which were each signed in late 2025.
It establishes new reporting standards for the possibility that the AI model could be used for large-scale harms, such as by providing users assistance in creating a chemical, biological or nuclear weapon or committing cyber-attacks.
