In this video, you'll learn what evals are, why testing an AI agent is different from testing regular software, and how to evaluate an agent with code checks, an LLM judge, and human review. Then we build an eval set for a text-to-SQL agent, use error analysis to find what's failing, calibrate an LLM judge against human labels, and fix the agent and rerun the evals.

AI Maker Residence 4

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. This fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
