A
Use Amazon Comprehend for summarization
B
Use Bedrock pre-trained FMs and apply prompt engineering
C
Start SageMaker training jobs with custom summarization datasets
D
Host a summarization model in EC2 Auto Scaling groups
Explanation:
Explanation
Correct Answer: B - Use Bedrock pre-trained FMs and apply prompt engineering
Why Option B is correct:
-
Minimal configuration requirement: Amazon Bedrock provides access to pre-trained foundation models (FMs) that require minimal configuration. You can use these models out-of-the-box without training or fine-tuning.
-
Prompt engineering approach: With prompt engineering, you can guide the model to perform summarization tasks by providing appropriate prompts and instructions, eliminating the need for model training.
-
Serverless and managed service: Bedrock is a fully managed service that handles infrastructure, scaling, and maintenance, aligning with the requirement for minimal configuration.
Why other options are incorrect:
A. Use Amazon Comprehend for summarization: While Amazon Comprehend does offer summarization capabilities, it's more limited compared to foundation models in Bedrock. Comprehend's summarization is more structured and may not handle complex document summarization as effectively as modern FMs.
C. Start SageMaker training jobs with custom summarization datasets: This requires significant configuration, data preparation, model training, and tuning - exactly what the team wants to avoid.
D. Host a summarization model in EC2 Auto Scaling groups: This involves managing infrastructure, model deployment, scaling, and maintenance - requiring substantial configuration and operational overhead.
Key AWS Services Context:
-
Amazon Bedrock: Provides access to foundation models (like Claude, Llama, etc.) through API calls with prompt engineering capabilities.
-
Prompt Engineering: The practice of designing and refining input prompts to get desired outputs from AI models without modifying the model itself.
-
Foundation Models: Large pre-trained models that can perform various tasks including summarization without additional training.
This approach best meets the requirements of minimal configuration and no model training/tuning while providing powerful summarization capabilities for large documents.
