1. What is the primary economic benefit of using an LLM routing platform?

   1. Matching query complexity to cost-appropriate models to reduce spending
   2. Sending every query to the most expensive frontier model available
   3. Guaranteeing faster response times than any single provider
   4. Automatically selecting the model with the most parameters

2. According to the evaluation method described, how should you compare a routing platform against always using a frontier model?

   1. Compare the prices of the router's API versus direct provider APIs
   2. Deploy the router to production and measure savings after one week
   3. Test only on your most difficult queries to see if routing can handle them
   4. Run 500 representative requests through both approaches and compare quality, cost, and p95 latency

3. Which of the following is explicitly listed as a hidden cost that requires attention when using routing platforms?

   1. Increased latency from routing decisions
   2. Model licensing fees
   3. API key management complexity
   4. Training data costs

4. What does the lesson say about the stability of routing platform behavior over time?

   1. Behavior may change without notice as platforms tune their classifiers
   2. Router classifiers remain frozen once trained
   3. Routing decisions become more predictable after the first month
   4. Routers only change behavior when you update your API keys

5. What key capability do routing platforms provide regarding different LLM providers?

   1. They eliminate the need for any API keys
   2. They automatically translate between programming languages
   3. They host their own models exclusively
   4. They provide a unified API across multiple providers

6. Why does the lesson recommend running an ongoing evaluation rather than a one-time test of a routing platform?

   1. The router's behavior can change as classifiers are updated
   2. One-time tests are more accurate than continuous monitoring
   3. Ongoing evaluation wastes computational resources
   4. One-time tests are required by routing platform terms of service

7. What fundamental capability enables routing platforms to reduce costs?

   1. Predicting task complexity and routing to cost-appropriate models
   2. Guaranteeing that cheaper models produce better output
   3. Automatically upgrading all queries to premium models
   4. Eliminating the need for any model evaluation

8. The lesson mentions that routing platforms cannot replace what essential component of an AI deployment?

   1. Your customer support team
   2. Your own evaluation suite
   3. Your frontend user interface
   4. Your data preprocessing pipeline

9. What is the primary risk associated with depending on a single routing platform vendor?

   1. They are illegal in certain jurisdictions
   2. They may go out of business or change pricing unexpectedly
   3. They always produce lower quality than direct provider access
   4. They require you to share your proprietary data publicly

10. When comparing routing platforms, what three metrics does the lesson specifically recommend tracking?

    1. Training time, parameter count, and token limits
    2. Speed, memory usage, and API uptime
    3. Quality, cost, and p95 latency
    4. Number of models supported, age of platform, and user interface design

11. What assumption makes a one-time evaluation of a routing platform insufficient?

    1. The classifier tuning process is static and unchanging
    2. The evaluation results are always accurate
    3. The platform's routing logic updates periodically
    4. The platform will have the same performance forever

12. What does the lesson identify as the fundamental tradeoff when using routing platforms?

    1. Trading simplicity for more configuration options
    2. Trading privacy for better pricing
    3. Trading speed for higher quality
    4. Trading cost savings for potential quality or latency risks

13. What does the lesson advise about the relationship between routing platforms and model evaluation?

    1. You should run an ongoing eval, not just a one-time test
    2. Routing platforms perform evaluation automatically
    3. Evaluation should only happen before selecting a router
    4. Routing platforms eliminate the need for any evaluation

14. What is provider abstraction in the context of routing platforms?

    1. Automatically selecting the cheapest provider for every request
    2. Limiting access to only one model's capabilities
    3. Providing a single API interface that works across multiple LLM providers
    4. Hiding the identity of the final model used from the user

15. If a routing platform shows 80% cost savings in testing, but p95 latency triples, what should you consider?

    1. The latency increase is irrelevant since you're saving money
    2. The platform is malfunctioning and should be abandoned
    3. You should immediately switch to a different routing platform
    4. The tradeoff may not be worth it depending on your application's latency requirements
