Cost-Optimize a 24/7 LLM API Cluster

FreeVerified credential4 weeksExpert

Overview

What this challenge is about.

Profile the current usage (24-hour trace, per-team breakdown). Pick a cost-optimization mix from: time-based autoscaling, spot/preemptible instances with graceful drain, smarter continuous batching (vLLM tuning), KV-cache aware request routing, model quantization to FP8 or AWQ, and request-class-based routing (cheap model for short queries). Prototype the top two on a small replica cluster. Validate SLA (p99 latency under 600ms) holds. Deliver a 4-page memo with projected USD savings and a 90-day rollout plan.

The Brief

What you'll do, and what you'll demonstrate.

Cut LLM cluster cost by 30%+ via a prototyped optimization mix, without breaking the p99 latency SLA.

Earning criteria — what you'll demonstrate

  • Profile real LLM-API usage to find cost-optimization levers
  • Apply autoscaling, batching, and routing techniques to LLM serving
  • Prove cost wins without breaking latency SLAs
  • Translate engineering wins into a CFO-readable savings story
