There are 3 modules in this course

This module establishes why performance is a product feature, not a backend afterthought. We connect latency, cost, and answer quality to user-perceived speed (p50 vs p95, jitter) and trust. You’ll define a minimal metric set-latency, throughput, tokens/sec, determinism, and win-rate-then build a lightweight benchmarking harness that runs a small eval set, logs prompts/outputs, and exports clean CSVs. By the end, you’ll have a reproducible baseline you can rerun on every change.

In this module, you'll trace where time actually goes: network hops, model inference, prompt bloat, and post-processing. You’ll learn practical prompt patterns that cut tokens without cutting quality, plus schema-first I/O that improves stability and parsing. We’ll add caching strategies for embeddings, RAG retrievals, and tool calls, including cache keys and invalidation rules to avoid stale answers. Expect clear heuristics for cold vs warm paths and a simple checklist to shave seconds-not just milliseconds.

The final module turns tuning into a disciplined workflow. You’ll run A/B/C tests across model tiers and prompt variants on the same dataset to compare latency, cost per task, and quality with simple stats - then pick a winner. We’ll cover safe scaling: concurrency limits, queues, backpressure, retries, timeouts, and graceful degradation/fallbacks. You’ll leave with a 30-day optimization plan and a production playbook that keeps your app fast, affordable, and reliable after launch.
