When anew versionof a third-party model is released, the deployer must ensure it still meets safety, performance, and compliance requirements - which calls for aformal audit.
From theAI Governance in Practice Report 2024:
"Any updates or changes to AI systems should trigger a re-evaluation to ensure continued compliance and performance." (p. 12)
"Post-market monitoring includes reassessing the impact of updated models or retraining." (p. 35)

Online platforms displaying user-specific content and targeted ads are common and generally accepted practices, making them least likely to raise concerns under consumer protection laws compared to the other scenarios involving more direct consumer impact or claims.

If it is possible to provide a rationale for a specific output of an AI system, that system can best be described as explainable. Explainability in AI refers to the ability to interpret and understand the decision-making process of the AI system. This involves being able to articulate the factors and logic that led to a particular output or decision. Explainability is critical for building trust, enabling users to understand and validate the AI system's actions, and ensuring compliance with ethical and regulatory standards. It also facilitates debugging and improving the system by providing insights into its behavior.

Statistical sampling is a data analysis technique rather than a testing method to evaluate responsible AI system performance, unlike risk probability/severity, adversarial robustness, and decision analysis.
