Caching & Cost Optimization for LLM Apps
LLM calls are slow and expensive. Learn caching strategies, prompt-token reduction, model routing, and batching to cut cost and latency in production.
Why Optimize Cost?
At scale, LLM API bills grow fast — you pay per input and output token on every call. Smart caching and routing can cut costs by an order of magnitude with no quality loss.
Exact-Match Response Cache
The simplest win: cache the full response keyed by the exact prompt. Identical requests return instantly and free.
const key = hash(model + JSON.stringify(messages));
const hit = cache.get(key);
if (hit) return hit;
const res = await llm(messages);
cache.set(key, res);All lessons in this course
