1. A healthcare company needs to process patient records containing sensitive medical information. They are deciding between using a frontier API (like GPT-4) or self-hosting an open-source model. What is the MOST important factor in their decision?

   1. Whether the frontier API has better natural language understanding capabilities
   2. Whether the open-source model supports more languages
   3. Data sovereignty requirements and regulatory compliance (HIPAA, GDPR)
   4. The total number of parameters in each model

2. A startup has limited MLOps experience and needs to deploy AI capabilities quickly. They have a small monthly budget. Which approach would likely be most practical?

   1. Setting up a Kubernetes cluster with open-source models
   2. Training their own model from scratch
   3. Using a frontier closed model API with managed infrastructure
   4. Building a custom GPU cluster from scratch

3. A company is comparing the token cost of using a frontier API versus self-hosting an open-source model. Why might self-hosting appear cheaper per token but actually be more expensive overall?

   1. Self-hosting requires GPU infrastructure, MLOps staff, security monitoring, and ongoing model updates
   2. Open-source models require more tokens to produce the same output
   3. Open-source licenses become more expensive at scale
   4. Frontier APIs charge for every API call regardless of success

4. A high-traffic application needs to process millions of requests daily. Which model deployment strategy would most likely optimize costs?

   1. Paying premium rates for dedicated frontier API endpoints
   2. Switching to a more expensive but faster frontier model
   3. Using a frontier API with pay-per-token pricing
   4. Self-hosting open-source models on owned GPU infrastructure

5. A financial services firm must comply with strict data residency laws that require all customer data to remain within their country's borders. What is their primary consideration when choosing between open-source self-hosting and frontier APIs?

   1. The number of available fine-tuning options
   2. The specific model architecture each option uses
   3. Whether the frontier provider can guarantee data never leaves the required geographic region
   4. The response speed of each model

6. A research lab needs access to the absolute latest model capabilities for cutting-edge experiments. Which option best meets this need?

   1. Self-hosting the newest open-source release
   2. Using frontier closed models which typically offer the most advanced capabilities
   3. Running older frontier models
   4. Training a model from scratch on new architectures

7. A company is planning their AI infrastructure for the next 12 months. They are uncertain about how the capability gap between open-source and frontier models might evolve. What does the lesson suggest about this uncertainty?

   1. The gap has already closed completely
   2. The gap will definitely widen in favor of frontier models
   3. The open-source vs. closed gap is unpredictable 12 months out
   4. Open-source models will definitely overtake frontier models

8. A retail company wants to add chatbot capabilities to their website. They expect low volume (a few hundred interactions monthly). What is the most cost-effective approach?

   1. Using a frontier API which would cost very little at low volume
   2. Building a custom model specifically for retail
   3. Deploying multiple open-source models for redundancy
   4. Self-hosting an open-source model on dedicated GPUs

9. An organization is comparing benchmarks showing frontier models outperforming open-source models. What crucial context might make these benchmarks misleading for their specific use case?

   1. Open-source models are never actually benchmarked properly
   2. Benchmarks only measure speed, not capability
   3. Generic benchmarks may not reflect performance on their particular workload and data
   4. Benchmarks are always conducted by frontier model companies

10. What operational responsibility comes with self-hosting open-source models that is avoided when using frontier APIs?

    1. Handling customer billing and payments
    2. Marketing the AI product
    3. Managing model updates and security patches
    4. Writing application code

11. A company chooses to use a hybrid approach: running customer service chatbots on open-source while using frontier models for complex analytical tasks. What does this demonstrate?

    1. Different workloads have different requirements that may favor different deployment options
    2. Hybrid approaches are more expensive than single-provider strategies
    3. Open-source models are always cheaper
    4. Frontier models cannot handle customer service

12. A tech company has an experienced MLOps team and needs to process sensitive financial data. They are comparing costs between frontier APIs and self-hosted open-source. What additional cost factor should they evaluate beyond direct API or infrastructure expenses?

    1. The cost of office furniture
    2. Marketing costs for promoting their AI features
    3. The operational burden including MLOps team time, security monitoring, and model update cycles
    4. The cost of coffee in the office break room

13. A company wants to deploy AI capabilities but has strict budget constraints and needs predictable monthly costs. Which deployment model generally offers more predictable expenses?

    1. Self-hosting with variable cloud GPU compute costs
    2. Paying per employee seat for AI tools
    3. Frontier APIs with fixed subscription or predictable per-token pricing
    4. Both options have equally unpredictable costs

14. What is the primary advantage of frontier closed models over open-source alternatives for organizations without dedicated ML infrastructure?

    1. They require no infrastructure management and provide fully managed services
    2. They can be customized more extensively
    3. They are free to use
    4. They always produce more accurate outputs

15. An organization wants to experiment with different model architectures to find what works best for their needs. What capability does self-hosting provide that frontier APIs typically don't?

    1. Direct access to model training processes
    2. Full flexibility to swap models, modify configurations, and customize deployment
    3. Guaranteed output quality
    4. Free access to all frontier models
