CCAO-F Claude Model Fundamentals Practice Question
A product manager is evaluating Claude models for a customer-support chatbot that must handle 50,000 conversations per day while keeping inference costs low. The conversations are short, factual, and do not require complex reasoning. Which Claude model is the most appropriate choice?
⚠ Common exam trap
The trap here is assuming that the most capable model is always the best choice, when cost and latency requirements often favor a smaller, faster model.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Claude 3 Haiku
The scenario demands a model that can handle high-volume, simple conversations at low cost. Claude 3 Haiku is specifically designed for speed and cost efficiency, making it the right fit for short, factual customer-support interactions. The other models offer greater capability but at higher cost, which is unnecessary for this use case.
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 2.1
Why it's wrong here
Claude 2.1 is an older-generation model with a 200K context window, but it is not optimized for cost or speed compared to Claude 3 Haiku. Using a legacy model for a new high-volume deployment would likely result in higher latency and cost, and it lacks the efficiency improvements of the Claude 3 family. It is not the best choice here.
- ✗
Claude 3 Opus
Why it's wrong here
Claude 3 Opus is the most capable and expensive model in the Claude 3 family, designed for complex reasoning and nuanced tasks. For short, factual customer-support conversations at high volume, its advanced capabilities are unnecessary and would significantly increase inference costs without improving the quality of simple responses. It is not the cost-effective choice for this scenario.
- ✓
Claude 3 Haiku
Why this is correct
Claude 3 Haiku is the fastest and most cost-effective model in the Claude 3 family, optimized for high-volume, straightforward tasks like simple customer-support queries. It delivers quick responses at low cost, making it ideal for 50,000 short, factual conversations per day where complex reasoning is not required. This aligns perfectly with the scenario's requirements.
- ✗
Claude 3.5 Sonnet
Why it's wrong here
Claude 3.5 Sonnet balances intelligence and speed, but it is more expensive than Claude 3 Haiku. For short, factual conversations that do not need advanced reasoning, using Sonnet would incur unnecessary costs. While it could handle the task, it is not the most cost-effective option when the workload is simple and high-volume.
