The verified answers are A. Model evaluation and C. AI model service cards. The question is specifically about explainability and transparency with model selections before a generative AI application goes to production. AWS AI Practitioner guidance identifies model selection as part of the foundation model lifecycle and includes evaluation as a required activity in that lifecycle. AWS also lists model-selection factors such as model type, performance requirements, capabilities, constraints, compliance, modality, latency, model complexity, customization, and input/output length. This means model evaluation directly supports responsible selection because it provides measurable evidence that a model meets the application’s business, technical, and governance requirements.
AI model service cards are also correct because AWS describes AI Service Cards as responsible AI documentation that improves transparency. AWS states that AI Service Cards provide information about intended use cases, limitations, responsible AI design choices, and performance optimization best practices for AWS AI services and models. AWS also links these cards to responsible AI areas such as fairness, bias, explainability, robustness, governance, transparency, privacy, and security. That directly addresses the company’s concern about transparency when choosing models.
Guardrails is not the best answer here. Guardrails are important for safety controls, denied topics, content filtering, and responsible runtime behavior, but the question focuses on explainability and transparency in model selection, not output filtering. Data encryption is incorrect because encryption protects data confidentiality at rest or in transit; it does not explain model behavior or document model limitations. Automated reasoning is also not the best match. It can support formal validation of specific policy-based logic, but it is not the primary AWS tool or technique for transparent model selection. Therefore, model evaluation and AI model service cards are the two techniques/tools that best address the stated requirement.
