Coming into force

Enacted AI law that starts applying after the data date, by month: plan the guard before the date, not after launch.

Informational data, not legal advice. Summaries are TwinEthos's own words and rules have not been reviewed by a lawyer: check the official text before relying on any of it. A guard addresses an item; adding it is not a statement that your code meets any law.

43 dated obligation starts from 38 rules in 9 jurisdictions, 1 Oct 2026 to 1 Jan 2029, as of the data date 2026-10-01. Stayed laws are listed with the date they would apply from. Dates change (amendments, stays, court orders): check the official source.
