The Brief

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

Replace a vendor classification API with a fine-tuned open-weight 3B model that beats it on quality, cost, or both — with a fallback plan.

Earning criteria — what you'll demonstrate

  • Apply LoRA fine-tuning to a 3B open-weight model on a real classification task
  • Benchmark a fine-tuned model against a vendor API on quality, latency, and cost
  • Design a deployment with a fallback path and basic monitoring
  • Reason about data-residency benefits of in-house LLMs
