CCAO-F Claude Model Fundamentals Practice Question
Network Topology
Refer to the exhibit. A company is building a translation service for live subtitles where latency must be under 200ms per segment. Which Claude 3 model family member is the only viable candidate based on the provided performance and cost data?
⚠ Common exam trap
Candidates often choose the 'most intelligent' model (Opus) instead of the 'fastest' model, ignoring the specific constraint that latency must be under 200ms, which is the defining requirement for live services.

Correct answer & explanation
✓
Claude 3 Haiku
In real-time applications like live subtitling, latency is the primary constraint. Even if a model is more intelligent, if it cannot meet the timing requirements, it is unusable. Claude 3 Haiku's ultra-low latency makes it the only choice for near-instantaneous feedback loops required for live media.
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 Opus
Why it's wrong here
While Opus has the highest intelligence, the exhibit shows it has 'Medium' latency, which is significantly slower than Haiku. For live subtitles, the delay in Opus's response would make the text out of sync with the audio, failing the primary requirement of the 200ms threshold.
- ✗
Claude 3 Sonnet
Why it's wrong here
Sonnet offers a good balance of intelligence and speed, but its 'Low' latency is still higher than Haiku's 'Ultra-Low' latency. In strict real-time environments like live subtitling, every millisecond counts, and Sonnet may not consistently meet the 200ms segment requirement for a smooth user experience.
- ✓
Claude 3 Haiku
Why this is correct
Haiku is specifically designed for speed. The exhibit lists it as 'Ultra-Low' latency, making it the most capable of meeting the 200ms requirement for live subtitles. Additionally, its low cost makes it economically viable for the high token volume generated by continuous live translation.
- ✗
All Claude 3 models are equally viable.
Why it's wrong here
The exhibit clearly shows significant differences in latency and cost between the three models. In a scenario with strict performance requirements and budget considerations, the models are not interchangeable; Haiku's speed and low cost make it the only logical choice for this specific real-time application.
