1.3.4. Cost Management

  • Concept: AI services have usage-based pricing with multiple dimensions
  • Purpose: Predict and control AI spending
  • Benefit: Avoid unexpected bills, optimize for value
Key Cost Factors:
FactorDescriptionOptimization
Transaction volumePer-call pricingBatch requests where possible
Data processedPer-character/image/minuteFilter unnecessary processing
Model typeGPT-4 > GPT-3.5-TurboUse appropriate model tier
Provisioned throughputReserved vs. pay-as-you-goReserve for predictable workloads
Key Trade-Offs:
  • Pay-as-you-go vs. Provisioned: PAYG offers flexibility but variable costs; provisioned offers predictability but commitment
  • Model Capability vs. Cost: More capable models cost more; right-size to requirements

Reflection Question: Your AI application costs spike unexpectedly. What diagnostic data would you examine first, and what are three potential causes?
