Reps. Jay Obernolte (R-CA) and Lori Trahan (D-MA) introduced legislation Thursday that would require large frontier artificial intelligence developers to undergo independent audits and provide transparency reports.The bill provides legislative text for one part of the draft legislation that the pair previously released, the Great American AI Act, which represents the most serious bipartisan effort yet to advance comprehensive AI measures.Congress came under added pressure to act on AI this week after the revelation that OpenAI models escaped containment and hacked the company Hugging Face with no human direction.

The bill introduced Thursday, the FRONTIER Act, would establish a national risk-based framework for AI governance, requiring large developers to provide transparency reports when deploying frontier models, establish risk-management frameworks, report critical safety incidents, and undergo third-party independent verification organization audits.“Artificial intelligence is advancing rapidly, and Congress must ensure our regulatory framework keeps pace without undermining American innovation,” Obernolte said in a statement. “This legislation will protect Americans from catastrophic risk, provide developers with clear rules of the road, and ensure the United States remains the global leader in AI,” he added.Frontier AI safety frameworks must be reviewed annually or within 30 days of any material modifications. Additionally, critical safety incidents must be reported no later than 24 hours after the frontier developer discovers them.“Americans deserve confidence that the most powerful models are being developed responsibly,” Trahan said in a statement.The measure is targeted only at large models, meaning those that have spent more than $1 billion on development in the past three years.The Great American AI Act
