CCDV-F Model Selection and Cost Management Practice Question
You are building a summarization feature that processes 20,000 support tickets nightly. Each ticket is under 4,000 tokens and the output summary is around 300 tokens. The job must complete within a 6-hour window and you want to minimize cost. Which Claude model should you choose?
⚠ Common exam trap
The trap here is assuming that a more capable model is always better, when the scenario explicitly prioritizes cost minimization for a simple task.

Correct answer & explanation
✓
Claude 3 Haiku
For high-volume, short-input summarization where cost is the primary constraint, Claude 3 Haiku provides the best balance of speed, quality, and price. Its lower per-token cost directly reduces the total spend for 20,000 requests, and its speed helps meet the 6-hour window. More expensive models like Sonnet or Opus are overkill for this task.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Claude 3 Sonnet
Why it's wrong here
Claude 3 Sonnet sits between Haiku and Opus in cost and capability. While it could handle the summarization, it is more expensive than Haiku and provides no decisive advantage for short, straightforward tickets. Choosing it would raise costs without a clear benefit, violating the requirement to minimize cost.
- ✗
Claude 3 Opus
Why it's wrong here
Claude 3 Opus is the most capable but also the most expensive model in the Claude 3 family. For summarizing short support tickets with a strict budget and a 6-hour deadline, its higher per-token cost is unnecessary and would inflate the total spend significantly without a commensurate quality gain on this straightforward task.
- ✗
Claude 3.5 Sonnet
Why it's wrong here
Claude 3.5 Sonnet offers strong quality but costs more per token than Haiku. For a simple summarization task on short tickets, the extra capability is not needed, and the higher cost would unnecessarily increase the total spend for 20,000 requests, making it a suboptimal choice when cost minimization is the goal.
- ✓
Claude 3 Haiku
Why this is correct
Claude 3 Haiku is the fastest and most cost-effective model in the Claude 3 family. For summarizing short tickets under 4,000 tokens with a modest 300-token output, Haiku delivers adequate quality at the lowest price per token, making it ideal for high-volume, budget-sensitive batch jobs that must finish within a 6-hour window.
