Cost-Quality Prompt Optimization at Scale

FreeVerified credential3 weeksExpert

Overview

What this challenge is about.

You receive 2,000 labeled code snippets (human rater consensus score 1-5) and budget for at most 8,000 API calls across the optimization run. Run a factorial sweep of 3 prompt strategies x 3 output schemas x 2 model tiers = 18 configurations on a 500-snippet subset, then evaluate the top 3 configurations on the full 2,000-snippet set. Compute Spearman correlation with human rater scores and per-call cost. Pick the Pareto frontier (cost vs. correlation) and recommend one configuration. Success is a recommendation that hits at least 40 percent cost reduction with correlation drop under 2 points.

The Brief

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

Find a Pareto-optimal prompt + model configuration that cuts spend by 40 percent on a 2M-call/week scoring pipeline without losing human-agreement quality.

Earning criteria — what you'll demonstrate

  • Design a factorial prompt + model experiment under a fixed call budget
  • Quantify the cost-quality trade-off rigorously (correlation, CIs, cost-per-call)
  • Choose between prompt strategies (zero-shot, few-shot, CoT) on evidence
  • Communicate optimization findings to an infrastructure-review audience
