   1. cost
   2. unit-economics
   3. tokens
   4. Test bounding-box and structured extraction quality

4. Which of these is directly relevant to Reasoning About Cost Per Task, Not Per Token?

   1. cost
   2. tokens
   3. Test bounding-box and structured extraction quality
   4. unit-economics

5. Which of the following is a key point about Reasoning About Cost Per Task, Not Per Token?

   1. Sum input plus output tokens per call.
   2. Aggregate spend by feature or user with tracing in place.
   3. Test bounding-box and structured extraction quality
   4. reasoning-models

6. What is one important takeaway from studying Reasoning About Cost Per Task, Not Per Token?

   1. Account for cost shifts when you change prompts.
   2. Predict cost without running on representative traffic.
   3. Test bounding-box and structured extraction quality
   4. reasoning-models

7. What is the key insight about "Cost-per-task model" in the context of Reasoning About Cost Per Task, Not Per Token?

   1. Test bounding-box and structured extraction quality
   2. reasoning-models
   3. For each feature: avg input tokens + avg output tokens + avg retries + tool-call overhead = task cost.

   1. Test bounding-box and structured extraction quality
   2. reasoning-models
   3. Note when reasoning hurts (well-specified transforms)
   4. A cheap model that needs 3 retries to get a valid answer can cost more than a strong model that nails it once.

9. What is the recommended tip about "Benchmark before committing" in the context of Reasoning About Cost Per Task, Not Per Token?

   1. Run your actual task samples against candidate models before choosing.
   2. Test bounding-box and structured extraction quality
   3. reasoning-models
