Step-by-Step Solution
Solution:
Step 1: Understand continuous evaluation benefits
Evaluating continuously with test inputs helps catch new errors and improve the chain before users see problems.Step 2: Compare other options
Running evaluation once or skipping it delays error detection. Random inputs without review do not ensure reliability.Final Answer:
Continuously evaluate with test inputs and update the chain before production. -> Option AQuick Check:
Continuous evaluation improves reliability = D [OK]
Quick Trick: Test often with real-like inputs before release [OK]
Common Mistakes:
MISTAKES- Thinking one-time evaluation is enough
- Ignoring errors until users report them
- Evaluating without checking results
