Section 1 of SB 25B-004 amends five subsections of the developer duty provision. The sole substantive change is replacing every instance of February 1, 2026 with June 30, 2026, extending the compliance deadline by approximately five months. A conforming edit replaces "promulgated" with "adopted" to describe the attorney general's rulemaking authority. The underlying obligations — reasonable care to avoid algorithmic discrimination, documentation and model-card availability to deployers, public use-case inventory disclosure, discrimination-risk reporting to the AG and deployers, and on-demand document production — remain unchanged.

Section 3 of SB 25B-004 amends the AI disclosure provision by replacing February 1, 2026 with June 30, 2026. The underlying obligation — requiring deployers and other developers who make an AI system intended to interact with consumers available to ensure disclosure to the consumer that they are interacting with an AI system — remains unchanged.
