AWS Certified AI Practitioner

Selecting a Generative AI Model

Turn the exam's list of selection factors into a working order of operations: eliminate on hard constraints, evaluate the survivors on your own task, then optimize for cost and latency.

Intermediate 18 minutes 5 Learning Objectives
  1. Identify the factors the exam names for selecting a generative AI model, and the additional factors AWS lists in the model selection lifecycle stage
  2. Apply the three gates in order: hard constraints, capability on your task, then cost and latency
  3. Compare the evaluation options in Amazon Bedrock: programmatic, judge model, and human
  4. Explain why the largest model is usually the wrong default and what model complexity actually costs
  5. Describe why model selection is reversible on Bedrock and what must be redone after a switch
