CCDV-F Model Selection and Cost Management Practice Question
A financial services firm is developing a customer support bot that requires low latency and high throughput for processing simple account inquiries. The firm expects over 500,000 requests per day and prioritizes cost-efficiency above the highest possible reasoning capabilities. Which model should the developer select to meet these specific business requirements?
⚠ Common exam trap
Candidates sometimes prioritize 'intelligence' benchmarks over business requirements, failing to realize that Haiku's low latency and cost are superior for simple, high-volume automated support interactions.
Answer choices
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
Selecting the right model involves balancing intelligence, speed, and cost. For high-volume, low-complexity tasks like account inquiries, Claude 3 Haiku offers the best performance-to-price ratio. It provides near-instant responses and significantly lower per-token costs compared to Sonnet or Opus, making it the industry standard for high-scale, simple automation where latency is a critical factor for user satisfaction.
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 3.5 Sonnet
Why it's wrong here
While this model offers a great balance of speed and intelligence, its cost is significantly higher than Haiku. For simple account inquiries that do not require complex reasoning, the extra expense and slightly higher latency would not be justified for a high-volume application processing millions of tokens daily.
- ✓
Claude 3 Haiku
Why this is correct
This model is specifically designed for speed and cost-effectiveness in high-volume applications. It handles simple tasks with minimal latency and has the lowest price point in the Claude 3 family. This makes it ideal for real-time customer support scenarios where response time and budget management are the primary technical constraints.
- ✗
Claude 3 Opus
Why it's wrong here
Opus is the most powerful model in terms of reasoning but is also the most expensive and has the highest latency. Using it for simple customer inquiries would lead to unnecessary costs and a slower user experience, as the model's advanced capabilities are overkill for basic account information retrieval tasks.
- ✗
Claude 2.1
Why it's wrong here
This older model lacks the architectural optimizations for speed found in the Claude 3 family. While it has a large context window, its cost-per-token and latency profiles are less competitive than Haiku's, making it a poor choice for a modern, high-throughput support bot requiring rapid execution and tight budget controls.
