Your question is Caching for High-Traffic LLMs. 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 layer to reduce latency and costs for a high-traffic LLM application?
Explain how you would form cache keys, choose between exact-match and semantic caching, handle expiration and invalidation, and prevent unsafe or incorrect responses. Cover the serving path, observability, capacity planning, and fallback behavior when the cache or embedding service is unavailable.
