1. A developer needs to sort 50,000 customer support emails into categories like 'billing,' 'technical,' and 'general.' Which model would be the most cost-effective choice?

   1. GPT-5 because it provides the most accurate classification
   2. DALL-E because it can visualize the emails
   3. GPT-4o-mini because it handles high-volume tasks cheaply
   4. Claude because it specializes in text analysis

2. A student wants to build a chatbot that answers questions about school lunch menus, bus schedules, and homework policies. Which model should they start with?

   1. A custom model trained from scratch on school data
   2. Claude because it has better safety features
   3. GPT-5 because school information is important and needs the best AI
   4. GPT-4o-mini because the task is simple and doesn't require advanced reasoning

3. Why might a company process a million daily customer messages using GPT-4o-mini instead of GPT-5?

   1. To significantly reduce costs while maintaining acceptable quality
   2. Because GPT-5 has stricter content filters
   3. Because GPT-5 requires special government approval
   4. Because GPT-5 cannot handle customer service queries

4. What is 'throughput' in the context of AI models like GPT-4o-mini?

   1. The speed at which the model generates text
   2. The maximum size of a single input the model can handle
   3. The number of different languages the model understands
   4. The amount of data the model can process in a given time

5. When should a developer consider upgrading from GPT-4o-mini to a larger model like GPT-5?

   1. When they need to process more images than text
   2. When the quality of outputs isn't good enough for the task
   3. When the API becomes too slow
   4. When they want to save money

6. What does 'cost-efficient' mean when describing GPT-4o-mini?

   1. The model requires fewer API calls to complete tasks
   2. The model runs on less expensive computer hardware
   3. The model is free to use for everyone
   4. The model provides good results relative to what it costs to use

7. What would be a bad use case for GPT-4o-mini?

   1. Classifying customer feedback into categories
   2. Generating quick replies to common questions
   3. Writing a complex mathematical proof that requires step-by-step reasoning
   4. Summarizing short paragraphs of text

8. An API (Application Programming Interface) allows developers to:

   1. Train their own AI models from scratch
   2. Build physical computer hardware for AI
   3. Create new AI models from nothing
   4. Send requests to use AI models like GPT-4o-mini in their own software

9. Why is the phrase 'match the model size to the task size' important?

   1. Smaller models always produce better results
   2. The model size must match the size of the input text
   3. Larger models are always faster than smaller ones
   4. Using the right model prevents wasting money on unnecessary power

10. What does it mean that GPT-4o-mini costs 'pennies per million tokens'?

    1. The model is more expensive than GPT-5
    2. The model is extremely cheap to use for most requests
    3. The model only charges for images, not text
    4. The model costs exactly one penny per million requests

11. What is the main advantage of using GPT-4o-mini for a class assistant chatbot?

    1. It can generate entire textbooks
    2. It can handle many student questions at very low cost
    3. It can replace teachers entirely
    4. It can grade student assignments automatically

12. A developer is building an app that needs to process 100,000 text entries per minute. Which characteristic of GPT-4o-mini would be most important?

    1. Its image recognition capabilities
    2. Its ability to generate creative fiction
    3. Its low cost per token makes high-volume processing affordable
    4. Its ability to understand complex emotional nuance

13. Why would a developer start with GPT-4o-mini when building an AI feature?

    1. It's the most cost-effective starting point that handles most tasks
    2. It never makes mistakes
    3. It's the most powerful model available
    4. It requires no coding to use

14. What type of model is GPT-4o-mini in relation to other OpenAI models?

    1. It's being discontinued by OpenAI
    2. It's a smaller, less expensive model compared to GPT-5
    3. It's only available to enterprise customers
    4. It's the largest and most powerful model OpenAI offers

15. If GPT-4o-mini processes an image poorly, what should you consider using instead?

    1. A different company's AI model
    2. A text-only model because images are too difficult
    3. GPT-5 because it reads images better
    4. Nothing — all models read images equally
