1. What is the main idea of "Comparing AI Evaluation Frameworks: Braintrust, Langfuse, Humanloop, Promptfoo"?

   1. How the major LLM eval platforms differ on tracing, scorers, datasets, and CI integration.
   2. Use AI as the final authority for the whole decision
   3. Avoid checking the answer once it sounds polished
   4. Focus only on speed instead of judgment

2. Which concept is most central to "Comparing AI Evaluation Frameworks: Braintrust, Langfuse, Humanloop, Promptfoo"?

   1. Braintrust
   2. evaluation-platforms
   3. Langfuse
   4. Humanloop

3. Which use of AI fits this topic best?

   1. Replace a thoughtful eval set with their starter datasets
   2. Let the AI decide what matters without your review
   3. Trace LLM calls with token cost, latency, and inputs/outputs
   4. Use the answer before checking whether it fits the situation

4. Which limitation should you watch for in this topic?

   1. Trace LLM calls with token cost, latency, and inputs/outputs
   2. Explain the topic in plain language
   3. Organize a draft for human review
   4. Replace a thoughtful eval set with their starter datasets

5. What should a careful learner remember about "Eval platform shortlist criteria"?

   1. Use AI to draft or organize ideas about evaluation-platforms, then verify before acting.
   2. Skip the context so the tool can guess faster
   3. Treat the output as private even after sharing it online
   4. Use the answer without checking the source

6. You want to use AI after this lesson. What is the safest next step?

   1. Act immediately because the AI answer is written clearly
   2. Use AI for drafting and comparison, but verify before publishing or relying on it.
   3. Hide uncertainty so the final answer looks cleaner
   4. Use private or sensitive details before checking permission

7. How should AI output about evaluation-platforms be treated?

   1. As proof that no other source is needed
   2. As a replacement for context, consent, or expert review
   3. As a draft or helper output that still needs human judgment and verification
   4. As something that becomes correct when it sounds confident

8. Name one way to verify an AI answer about evaluation-platforms.

9. Which action would help you apply "Comparing AI Evaluation Frameworks: Braintrust, Langfuse, Humanloop, Promptfoo" responsibly?

   1. Score qualitative dimensions reliably without human labels
   2. Use the tool to avoid thinking through the tradeoff
   3. Keep going even if the output conflicts with a trusted source
   4. Run scorers (LLM-as-judge, deterministic, human) on stored runs

10. Which choice is a bad use of AI for this lesson?

    1. Score qualitative dimensions reliably without human labels
