1. At what point does running local LLMs typically become more cost-effective than paying for API-based hosted inference?

   1. When you process fewer than 50 prompts per month
   2. When you want to use the newest available model
   3. Only when you need real-time responses under 100ms
   4. When your monthly bill for batch inference exceeds a certain threshold

2. Which scenario is NOT mentioned as a case where local AI models typically pay off?

   1. You require fully offline operation
   2. You need the absolute latest frontier-model reasoning capabilities
   3. Running high-volume batch inference where per-token costs add up
   4. Data is regulated and cannot leave your security perimeter

3. What is a fundamental limitation of local LLMs compared to frontier hosted models?

   1. They typically cannot match frontier-model reasoning at smaller parameter counts
   2. They cannot be customized for specific tasks
   3. They require constant internet connectivity to function
   4. They always produce lower-quality output regardless of size

4. After downloading model weights for offline use, what can a local LLM still do?

   1. Automatically update its knowledge base with new information
   2. Improve its performance through self-training
   3. Generate text and run inference without any internet connection
   4. Switch to different model architectures without downloading

5. Why might an open-weight model that scores close to a frontier model on public benchmarks still perform poorly on your specific task?

   1. Public benchmarks test general capabilities, not your particular use case
   2. The model was intentionally designed to fail on specific tasks
   3. Open-weight models always lie about their benchmark scores
   4. Benchmark scores have no relationship to actual performance

6. What hardware advantage do local LLMs typically have over large frontier models?

   1. They need no GPU and run on CPU alone
   2. They require data center-grade cooling systems
   3. They require specialized quantum computing hardware
   4. They can run on commodity GPUs at smaller parameter counts

7. Before committing to a specific open-weight model for production use, what should you do according to the key principles?

   1. Choose whichever model has the most parameters
   2. Accept the public benchmark scores as definitive
   3. Re-benchmark the model against your own evaluation set
   4. Skip testing since benchmarks are sufficient

8. When the material discusses the 'cost vs. quality tradeoff,' what does it refer to?

   1. Hosted models being more expensive but less capable
   2. The tradeoff between model speed and energy consumption
   3. Local models being cheaper but typically lower in reasoning quality compared to frontier models
   4. The price of hardware versus the physical size of the model

9. What does 'ergonomics' refer to when comparing local versus hosted AI models?

   1. The model's ability to understand human body language
   2. Energy efficiency of the inference process
   3. Developer experience and ease of integration
   4. The physical weight of the computing hardware

10. A colleague says local models 'lose on ergonomics.' What does this mean in practice?

    1. Local models are physically uncomfortable to use
    2. Local models require less technical skill to operate
    3. Hosted solutions typically offer better developer experience and easier integration
    4. There is no difference in usability between local and hosted

11. What is a 'batch workload' in AI inference?

    1. The process of training a model on new data
    2. Processing large volumes of requests in bulk, often scheduled in advance
    3. A single user query processed in real-time
    4. A continuous stream of conversational messages

12. Why might healthcare or financial organizations benefit from local LLMs?

    1. They require no technical expertise to deploy
    2. They allow sensitive data to remain within compliance boundaries rather than sending it to external APIs
    3. They always provide better quality output than hosted models
    4. They are significantly cheaper than all other options

13. If you need to update a local LLM with new knowledge, what must you typically do?

    1. Type new information into a configuration file
    2. Re-download the model weights with the new information
    3. Wait for the model to update itself automatically
    4. Nothing — local models never need updates

14. What is required to achieve 'hosted-grade reliability' with local models?

    1. Automatic updates from the model developers
    2. Nothing — local models are inherently as reliable as hosted services
    3. A premium subscription to the model provider
    4. Additional operational effort including monitoring, scaling, and failover systems

15. Why can local LLMs serve high-throughput batch workloads more cheaply than API providers?

    1. They are always faster than hosted alternatives
    2. They avoid per-token API pricing once hardware is purchased
    3. They use fundamentally more efficient algorithms
    4. They require no electricity to operate
