What changed between versions

Introduced Current/Final · 7 edits
MODERATE
The bill was renumbered from SB 4 to SB 4/EN (Engrossed version) and updated page numbers. The most significant substantive change is the redefinition of 'Artificial intelligence' to focus on machine learning and statistical models rather than general machine capabilities. Several definitions were reorganized and clarified, particularly around high-risk AI systems and developer/deployer roles. The bill also added new duties for the Commonwealth Office of Technology.
Scope change
The bill's scope was expanded to include foundation models and general-purpose AI models as distinct categories, while clarifying what is excluded from high-risk AI system definitions. The applicability was narrowed for internal AI systems and expanded for external systems.
DEFINITION

Redefinition of 'Artificial intelligence' to specifically mean machine learning and statistical models that train computer systems, replacing the broader definition about machines performing tasks under varying circumstances.

New definition for 'Foundation model' covering machine learning models trained on broad data at scale for general output.

New definition for 'General-purpose artificial intelligence model' covering models with significant generality capable of performing wide range of tasks.

Clarified 'High-risk artificial intelligence system' definition to explicitly include consequential decisions and added exclusions for narrow procedural tasks and preparatory assessments.

Reorganized and renumbered definitions from (1)-(20) to (1)-(20) with some items consolidated and others split for clarity.

ELIGIBILITY

Narrowed 'Deployer' definition to specifically apply to state departments, agencies, or administrative bodies in the Commonwealth.

REQUIREMENT

Added new duties for the Commonwealth Office of Technology including serving as single information technology authority for the Commonwealth.
