Your question is High-Concurrency LLM Serving Optimization. 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 optimize LLM serving for high concurrency without sacrificing response time?
Discuss the serving architecture, batching strategy, memory and cache management, autoscaling, admission control, and model-level optimizations you would evaluate. Explain how you would measure latency, throughput, quality, cost, and failure behavior before and after changes.
