# Illinois Governor Signs Landmark AI Safety Law Requiring Catastrophic Risk Framework

> Illinois has become the third US state to pass comprehensive AI safety legislation, following California and New York, with Governor Pritzker signing a bill that targets the far end of the risk spectrum. The law requires developers of large AI models to identify and assess catastrophic risks and to publish a formal risk-management framework describing how they handle them. Catastrophic risk is defined concretely: an incident with the potential for 50 or more deaths or more than $1 million in property damage. The approach is notable because it regulates process and disclosure rather than banning specific capabilities, an attempt to force transparency without freezing the technology in place. It also deepens a growing patchwork. With three states now enforcing their own frameworks and the EU AI Act already in force, developers face a thickening web of overlapping obligations, and the pressure for some federal baseline keeps rising. For anyone building or deploying frontier models, publishing a public safety framework is quietly shifting from good practice to legal requirement.
