Artificial intelligence: defenses.

Abstract

Existing law provides that everyone is responsible not only for the result of their willful acts, but also for an injury occasioned to another by their want of ordinary care or skill in the management of their property or person. Existing law requires the developer of a generative artificial intelligence system or service that is released on or after January 1, 2022, and made publicly available to Californians for use, to post on the developer's internet website documentation regarding the data used by the developer to train the generative artificial intelligence system or service. Existing law defines "artificial intelligence" for these purposes. This bill would prohibit a defendant who developed, modified, or used artificial intelligence, as defined, from asserting a defense that the artificial intelligence autonomously caused the harm to the plaintiff.
