Inference & Serving

KV cache, prefill vs. decode, PagedAttention, continuous batching, and caching.

Use this path when latency, throughput, memory, or serving cost becomes the bottleneck.2 sessions

What You’ll Be Able to Do

  1. 01Explain why decode is bandwidth-bound and prefill is compute-bound
  2. 02Estimate KV-cache memory and why it caps concurrency
  3. 03Contrast prompt caching with semantic caching and their risks
