Optimization

Concept

LLM Cost Optimization

The operational playbook for cutting LLM spend without cutting quality. Model routing, caching, batching, and the metrics that actually matter.

Interview

Walk me through how Adam works, and when you'd use it vs SGD with momentum.

Tests deeper optimizer knowledge — separates 'studied for the interview' from 'has shipped models'.

Interview

What's the difference between L1 and L2 regularization, and when would you use each?

Quick check on fundamental ML knowledge — and whether you can connect math to practical model behavior.

Prompt

Fix a Prompt That's Too Long

Compress a bloated prompt without losing intent, constraints, or output quality.
