1. What does the term "open weights" refer to in an AI model?

   1. The model's internal parameters are publicly available for inspection and modification
   2. The model can be downloaded and run on personal devices
   3. The model produces outputs that anyone can see and share
   4. The model is free to use without any restrictions

2. A student wants to use an AI chatbot but is concerned about their conversations being seen by the company that runs the AI. Which type of model would better address this concern?

   1. A model that runs entirely on their own computer
   2. A model that requires a subscription fee
   3. A closed model accessed through a paid API
   4. A model hosted on a remote server

3. Which of these AI models is an example of a closed model?

   1. Mistral
   2. Gemma
   3. GPT-5
   4. Llama 3

4. What is a primary advantage that closed models typically have over open models?

   1. Easier to modify and customize
   2. More advanced capabilities for cutting-edge tasks
   3. Greater transparency in how they work
   4. Lower cost for individual users

5. A researcher wants to study exactly how a neural network processes text to reach its conclusions. What type of model would allow this kind of study?

   1. A closed model accessed via API
   2. A model with open weights that can be downloaded
   3. A proprietary model with hidden parameters
   4. A model that charges per query

6. What does it mean to perform "local inference" with an AI model?

   1. Using AI to make decisions about local businesses
   2. Processing AI requests on your own device rather than sending data to the cloud
   3. Training a model on data from your local area
   4. Running the model on a server far away from the user

7. A company is building an AI feature for their product and wants to avoid paying per-query fees as usage grows. Which type of model would likely be more cost-effective at scale?

   1. A model that charges based on output length
   2. An open model that can be hosted on company servers
   3. A closed model accessed through an API
   4. A subscription-based model

8. What piece of information would you typically find on a model's page at huggingface.co?

   1. The license that tells you how you can legally use the model
   2. The model's favorite color
   3. The phone number of the model developers
   4. The exact price the model charges per response

9. What is a typical payment model for using closed AI systems like Claude or Gemini?

   1. Paying for each individual query or amount of text processed
   2. Paying a monthly subscription fee
   3. Paying based on how many people have access to the model
   4. Paying only for the initial download

10. Why do privacy-conscious users often prefer open AI models?

    1. Data processed locally doesn't get sent to external servers
    2. Open models never make mistakes
    3. Open models are required by law to protect privacy
    4. Open models are always more accurate

11. What does it mean when an AI model is described as "open source"?

    1. The model can be used without any restrictions whatsoever
    2. The model generates only open-source code as output
    3. The model's weights, architecture, and training code are publicly available
    4. The model must be connected to the internet to function

12. A machine learning researcher wants to fine-tune an AI model for a specific task, such as analyzing medical texts. Which type of model would be easier to modify for this purpose?

    1. A model that only works in the cloud
    2. An open weights model that can be downloaded
    3. A closed model accessed via API
    4. A proprietary model with encrypted parameters

13. When you use a closed AI model through a web interface, what typically happens to your prompts?

    1. They are shared with all other users of the model
    2. They are sent to the company's servers where the model runs
    3. They are stored only on your device
    4. They are automatically deleted after one use

14. Which type of model is more likely to receive the latest improvements and new capabilities first?

    1. Both receive improvements at exactly the same time
    2. Open models because anyone can contribute improvements
    3. Neither type can be improved after release
    4. Closed models because the company controls development

15. What is a major tradeoff when choosing to run an open AI model locally instead of using a closed API?

    1. You avoid per-query fees but sacrifice all ability to customize the model
    2. You get better privacy but must share your data with more companies
    3. You gain unlimited free access but need capable hardware and technical setup
    4. You need faster internet but can use any model available
