Plain-language change summary

The amendment to Senate Bill 4 updates the mandated effective date for developers of high-risk artificial intelligence systems to ensure they take care to prevent algorithmic discrimination. Originally set for February 1, 2026, the new deadline is now June 30, 2026. This change matters because it allows developers more time to implement necessary measures to protect consumers from potential biases, ensuring these systems are fair and equitable before they go into effect.
