Massachusetts lawmakers are weighing some of the toughest state-level artificial intelligence rules in the U.S.

The state Senate passed an economic development bill last month requiring AI labs to go through independent reviews of the “catastrophic risks” every 120 days, Bloomberg reported. The results would be publicly released, but the state would not have the authority to use them to stop AI development.

The border legislation is expected to pass in the legislature prior to the November election, due to the fact that it includes funding for projects in lawmakers’ home districts. A six-member negotiating committee made up of the House and Senate members is now working to resolve the remaining differences, including the AI provisions.

Bloomberg noted that Anthropic retained Boston-based lobbying firm Tremont Strategies Group earlier this year and OpenAI recently hired lobbying shop Benchmark Strategies to lead the effort.

Cesar Fernandez, Anthropic’s head of U.S. State and Local Government Relations, stated in a post on X that the company is in favor of the new laws: “We applaud the Massachusetts Senate for passing the clearest and strongest AI safety legislation in the country. The Senate’s economic development bill raises the bar on AI safety while ensuring that innovation is able to continue.”

“We have long believed frontier AI safety is best addressed by a strong federal standard. But powerful AI won’t wait for consensus in Washington and Massachusetts just showed what thoughtful state leadership looks like,” he continued.
