LawAI SafetyAI GovernanceRisk

Catastrophic Risk

A term used in frontier AI safety law for specified extremely severe harms or risks. The exact definition depends on the applicable law and should not be treated as universal.

Why it matters: Catastrophic-risk laws establish special duties for certain frontier AI developers, while the underlying focus on extreme severity can also inform broader risk analysis without extending those legal duties to organizations outside scope.

ForHumanity TermAI GovernanceRisk

Diverse Inputs and Multi-Stakeholder Feedback (DIMSF)

A ForHumanity governance concept for deliberately incorporating people with varied lived experiences, backgrounds, cultures, perspectives, skills, expertise, protected categories, and intersectionalities into risk input, evaluation, and assessment across the system lifecycle.

Why it matters: Governance decisions can miss material impacts when they rely on a narrow set of perspectives.

AuditDIFFAI SafetyRiskThird-Party RiskAI Governance

Downstream Risk

Risk that emerges or changes when an organization deploys an AI model within its own environment, combining upstream model capabilities, safeguards, and limitations with local access, data, tools, autonomy, scale, and business processes.

Why it matters: A model provider's safety controls do not fully describe the risk created by a customer's deployment. Auditors need to examine both upstream dependencies and the conditions the deploying organization controls.

F

LawAI SafetyAI Governance

Frontier Model

A highly capable foundation model that meets a technical threshold defined by an applicable frontier AI law. The precise threshold and related requirements depend on the jurisdiction.

Why it matters: Whether a model meets a legal frontier-model definition can determine whether special safety, transparency, assessment, and incident-reporting requirements apply to its developer.

Audit & AssuranceAudit & AssuranceAI Governance

Independent Assurance

Evaluation performed with sufficient independence from the activity being assessed to provide credible confidence in the result.

Why it matters: Independence helps separate an organization's own claims about its program from an external evaluation of evidence against defined criteria.

California LawAI GovernanceAudit & AssuranceRisk

Independent Verification Organization (IVO)

Under California SB 813, an Independent Verification Organization, or IVO, is an AI auditor designated by the Government Operations Agency as having demonstrated expertise in assessing risks associated with artificial intelligence and identifying the metrics and methodologies used to conduct those assessments.

Why it matters: California is creating an IVO designation to identify AI auditors that meet state-developed expectations for expertise, risk assessment, conflicts of interest, and independence.

International StandardAI GovernanceStandardsAudit & Assurance

ISO/IEC 42001

ISO/IEC 42001:2023 is an international management system standard that specifies requirements for establishing, implementing, maintaining, and continually improving an artificial intelligence management system.

Why it matters: It gives organizations a structured management-system approach for governing AI-related risks, responsibilities, objectives, controls, monitoring, and continual improvement.

M

California CCPA RegulationPrivacyRiskGovernance

Material Change

A meaningful change to covered processing that creates new negative impacts, increases an existing impact, or makes a safeguard less effective.

Why it matters: A material change can trigger an update to a CCPA risk assessment as soon as feasible and no later than 45 calendar days after the change.

AuditDIFFAI SafetyRiskAudit & Assurance

Maximum Credible Harm

The most severe reasonably foreseeable harm an AI system could cause or materially contribute to, used as a starting point for reasoning backward through the conditions, capabilities, failures, and controls that shape the risk.

Why it matters: Starting with harm can prevent an assessment from being constrained by the controls an organization already has and can make severe risk pathways easier to test.

N

California CCPA RegulationPrivacyRisk

Negative Impact

A harmful consequence that processing personal information may create for a consumer.

Why it matters: A CCPA risk assessment must identify relevant negative impacts and weigh privacy risks against the benefits of the processing.

Industry UsageAI SafetyRiskAI Governance

Systemic Societal Risk

AI risk that can spread, accumulate, interact, or scale across populations, institutions, markets, infrastructure, or other parts of society rather than remaining confined to one user, system, or organization.

Why it matters: Some AI harms become important because of scale, repetition, interconnectedness, concentration, or correlated failures. Evaluating only direct organizational impacts can miss those broader pathways.
