In one paragraph

Illinois' Artificial Intelligence Safety Measures Act regulates developers of frontier AI models (trained with more than 10^26 operations), with most duties on large frontier developers, those with over $500 million in annual gross revenue with affiliates. From January 1, 2027 large frontier developers need a current disclosure statement on file with the state to develop, deploy or operate a frontier model in Illinois; from January 1, 2028 they must publish and follow a frontier AI safety framework and undergo annual independent audits.
