Doing CRediT right? Don’t stop at the statement.
A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

A first-of-its-kind state law
Signed into law in 2024, the Colorado AI Act is widely described as the first comprehensive US state statute governing artificial intelligence, in contrast to the narrower, sector-specific measures other states had adopted. Its central concern is algorithmic discrimination — the risk that AI used in important decisions could produce unlawful differential treatment on the basis of protected characteristics. The law places duties on both developers, who build high-risk AI systems, and deployers, who put them to use, structured around a standard of reasonable care to protect consumers.
High-risk systems and consequential decisions
The Act focuses on high-risk AI systems, which it broadly describes as those that make, or are a substantial factor in making, a consequential decision. Consequential decisions are those with a material effect on a consumer’s access to or terms of things such as employment, education, financial or lending services, housing, healthcare, insurance, legal services or essential government services. Developers and deployers are expected to use reasonable care to avoid algorithmic discrimination and, in defined circumstances, to provide documentation, conduct impact assessments and give consumers certain notices.
Effective date and amendment
The Colorado AI Act was originally scheduled to take effect in 2026, but its implementation date has been the subject of legislative attention and amendment, reflecting ongoing debate about its scope and the readiness of affected organisations. Because the precise commencement and detailed obligations have been revisited since enactment, the operative requirements should be read against the law’s current amended text. The Act has nonetheless been influential as an early model for state-level, discrimination-focused AI regulation in the United States.

Common misconceptions
What people often get wrong
Often heard: The Colorado AI Act is a federal United States AI law.
Actually: It is a state law, enacted by Colorado as Senate Bill 24-205. It applies within Colorado rather than nationwide, and is notable as the first comprehensive AI statute at the US state level.
Often heard: The Colorado AI Act regulates every use of artificial intelligence.
Actually: Its core duties focus on high-risk AI systems involved in consequential decisions, such as those affecting employment, housing, lending or healthcare, rather than all AI uses.
Often heard: The Colorado AI Act took effect immediately on being signed.
Actually: Its effective date was set for the future, originally 2026, and has been the subject of amendment. The commencement should be read against the law’s current text.
