Virginia HB 713 establishes the FAIR AI Act, which imposes a disclosure obligation on developers of base artificial intelligence models requiring them to publish specified model information in their terms of service. The bill eliminates 'the AI did it' as a defense in civil and criminal actions for both developers and deployers, preventing defendants from arguing that autonomous AI conduct shields them from liability. It creates the FAIR AI Enforcement Fund, administered by the Attorney General, to support state agency enforcement against AI system misuse, bias, and workforce disruption. The bill does not create a private right of action, nor does it specify monetary penalties or remedies. The bill was left in committee and has not been enacted.
