3. Cost Management — Hemat 5-10x

Teknik yang dipakai production teams
TechniqueSavingsHow It WorksTrade-off
Prompt Caching50-90%Cache repeated system prompts (Anthropic, OpenAI)Only for static prefixes
Semantic Caching30-60%Cache similar queries with embedding similaritySlightly stale answers
Model Routing40-70%Simple query → cheap model, complex → premiumRouting accuracy matters
Prompt Compression20-40%LLMLingua: compress prompts, keep meaningSlight quality loss
Batch Processing50%Anthropic Batch API: async, half priceHigher latency
Self-hosted60-80%Run open model (Qwen, LLaMA) on own GPUOps overhead, lower quality

4. Monitoring & Observability

Track everything: latency, cost, quality, errors
MetricWhat to TrackTools
Latency (p50/p95/p99)Response time distributionDatadog, Grafana, custom
Token UsageInput/output tokens per requestAPI billing, LangSmith
Cost per QueryTotal cost including infraCustom dashboard
Error RateFailed requests, timeoutsPrometheus, PagerDuty
Quality ScoreLLM-judge score on sampleW&B Weave, Braintrust
Safety Rate% passing content filterGuardrails AI logs
User SatisfactionThumbs up/down, NPSIn-app feedback

Selamat! Seri Belajar LLM Complete!

10 Part, dari "apa itu next-token prediction" sampai production deployment. Anda sekarang memahami entire LLM stack: cara kerja, cara dipakai, cara di-deploy, dan cara diamankan. Welcome to the frontier.

What's Next? Roadmap Lanjutan

Build: 3-5 projects end-to-end (RAG chatbot, agent, fine-tuned model). Learn: Hugging Face courses, Anthropic prompt engineering docs. Practice: Kaggle LLM competitions. Deploy: Ship something to real users. Stay current: Follow Sebastian Raschka, Andrej Karpathy, Hugging Face blog. Remember: the best way to learn LLMs is to build with them.
