Building and training a generative AI model from scratch provides the company with the most ownership and control over security responsibilities. In this scenario, the company is responsible for all aspects of the security of the data, the model, and the infrastructure.

Option D (Correct): " Building and training a generative AI model from scratch by using specific data that a customer owns " : This is the correct answer because it involves complete ownership of the model, data, and infrastructure, giving the company the highest level of responsibility for security.

Option A: " Using a third-party enterprise application that has embedded generative AI features " is incorrect as the company has minimal control over the security of the AI features embedded within a third-party application.

Option B: " Building an application using an existing third-party generative AI foundation model (FM) " is incorrect because security responsibilities are shared with the third-party model provider.

Option C: " Refining an existing third-party generative AI FM by fine-tuning the model with business-specific data " is incorrect as the foundation model and part of the security responsibilities are still managed by the third party.

Generative AI Security Scoping Matrix on AWS: AWS provides a security responsibility matrix that outlines varying levels of control and responsibility depending on the approach to developing and using AI models.

Amazon SageMaker Clarify provides built-in tools to detect bias in data and models, and to generate detailed explainability reports for model predictions, including SHAP values and feature importance.

A is correct:

“Amazon SageMaker Clarify provides bias detection, explainability for ML models, and comprehensive reports to satisfy regulatory and ethical requirements.”

(Reference: Amazon SageMaker Clarify Overview)

B (Data Wrangler) is for data preparation, not bias/explainability.

C (Model Cards) document models, but don’t detect bias or explain predictions.

D (AI Service Cards) provide transparency for AWS AI services, not custom model explainability.

Decreasing the number of tokens in the prompt reduces the cost associated with using an LLM model on Amazon Bedrock, as costs are often based on the number of tokens processed by the model.

Token Reduction Strategy:

By decreasing the number of tokens (words or characters) in each prompt, the company reduces the computational load and, therefore, the cost associated with invoking the model.

Since the model is performing well with few-shot prompting, reducing token usage without sacrificing performance can lower monthly costs.

Why Option B is Correct:

Cost Efficiency: Directly reduces the number of tokens processed, lowering costs without requiring additional adjustments.

Maintaining Performance: If the model is already performing well, a reduction in tokens should not significantly impact its performance.

Why Other Options are Incorrect:

A. Fine-tuning: Can be costly and time-consuming and is not needed if the current model is already performing well.

C. Increase the number of tokens: Would increase costs, not lower them.

D. Use Provisioned Throughput: Is unrelated to token costs and applies more to read/write capacity in databases.
