1. Which sentence best captures the main idea of 'What does an AI agent actually cost per task?'?

   1. Tools and goals are unnecessary for agent design
   2. Agents should always run without limits or oversight
   3. Agents call models many times — the per-task bill is sneaky bigger than chat.
   4. Agents and chatbots are the same thing in every way

2. Which of the following is part of 'Some examples'?

   1. Avoid taking any actions in the world
   2. Use the most expensive model regardless of fit
   3. Track tokens per run.
   4. Approve all actions automatically

3. Which of the following is part of 'The rule'?

   1. Always run with no oversight
   2. Skip every form of evaluation
   3. Run unbounded retries on any error
   4. Measure the cost of one run before you scale to a thousand.

4. Which of the following is part of 'You did it!'?

   1. Always run with no oversight
   2. Use the most expensive model regardless of fit
   3. Run unbounded retries on any error
   4. You won't get billing-shock now.

5. What is 'token cost' in this context?

   1. A reason to skip all logging
   2. A way to disable the agent's tools
   3. A core concept covered in What does an AI agent actually cost per task?
   4. A trick to bypass approvals

6. What is 'billing' in this context?

   1. A core concept covered in What does an AI agent actually cost per task?
   2. A reason to skip all logging
   3. A way to disable the agent's tools
   4. A trick to bypass approvals

7. Which formula best estimates an agent's real cost per task?

   1. The cost of the cheapest call only
   2. Just the price of one model call
   3. The price of the GPU
   4. Sum of all model calls and tool fees per run, divided by completed tasks (not attempts)

8. Why does a multi-agent system sometimes outperform a single agent on complex jobs?

   1. Single agents cannot use tools
   2. More agents always means more accuracy
   3. Specialized roles can divide work and check each other
   4. Multiple agents always cost less

9. Which signal best tells you an agent is stuck in a runaway loop?

   1. It asks one clarifying question
   2. It keeps repeating the same tool call with no new progress
   3. It finishes the task in one step
   4. It returns a short summary and stops

10. Why does an AI agent need 'tools' such as a browser, calendar, or code runner?

    1. Tools replace the need for any prompts
    2. Tools shrink the context window
    3. Tools let the agent take actions in the world instead of only producing text
    4. Tools make the model speak more naturally

11. Which budget control most directly prevents runaway costs from an agent loop?

    1. A bigger model
    2. A friendly system prompt
    3. A hard cap on steps, tokens, or dollars per task
    4. A longer context window

12. What is the most reliable way to keep an autonomous agent from going off the rails on a long task?

    1. Trust the model to know when to stop
    2. Disable its tools so it can only think
    3. Run it for as many steps as possible without checking in
    4. Set a clear goal, a step budget, and review checkpoints

13. Why is it dangerous to give an agent access to your email and calendar without scoped permissions?

    1. Scoped permissions slow the model down
    2. It will refuse to work
    3. Scopes only matter for paid accounts
    4. Broad access means a single misstep can send the wrong message or wipe events

14. What is the best response when an agent suggests an action you do not understand?

    1. Run it twice to be sure
    2. Approve it to keep things moving
    3. Ask the agent to explain the action and its expected effect before approving
    4. Reject everything and stop using the agent

15. What does an 'eval' for an agent measure?

    1. The exact wording of every prompt
    2. How polite the model sounds
    3. The temperature setting
    4. Whether the agent reliably completes a defined task end to end
