Your question is Caching Strategy for LLM Serving. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you implement a caching strategy for LLM serving to improve response times? Explain cache key design, exact and semantic caching, invalidation, storage, consistency, and how you would measure quality and latency. Discuss how the design handles streaming responses, personalization, nondeterministic generation, prompt or model changes, privacy, and cache failures.
