The bill amends Chapter 9-1 of the General Laws by introducing a new section, 9-1-55, which establishes liability for injuries caused by artificial intelligence (AI). It defines key terms such as "artificial intelligence," "covered model," and "developer," and outlines the conditions under which developers of covered models or derivatives can be held strictly liable for injuries to non-users. Specifically, liability applies if the injuries are caused by conduct of the AI that would constitute negligence or an intentional tort if performed by a human, and if such conduct was neither intended nor reasonably anticipated by the user or any intermediary involved in modifying the model.

Additionally, the bill includes provisions for rebuttable presumptions regarding the mental state of the AI in tort cases, stating that if a human would have acted with a certain mental state under similar circumstances, the AI is presumed to have that mental state as well. It also allows for affirmative defenses for developers, such as proving that the AI met the standard of care applicable to humans or that the injuries resulted from a capabilities failure rather than negligence. The act is set to take effect upon passage.
