Jev for beginners: how to use it and what to build

Jev is TypeSafe AI’s new decision model. It returns type-safe structured values (a choice, a score, a probability) instead of generated text, at 4 cents per million input tokens with no output charge. This week I ran it on five real projects: PR categorization, a meta-analysis of my own Claude and Codex sessions, Gmail triage, the ChatPRD product insights graph, and a live audience dashboard built from 4,500 YouTube comments.

Listen or watch on YouTube, Spotify, or Apple Podcasts

What you’ll learn:

1. What makes Jev fundamentally different from every other model I’ve used
2. How I analyzed 1,700 PRs for 9 cents and what I found out about where my engineering effort actually went
3. The personal meta-analysis you can run on your own Claude and Codex sessions right now
4. Why I stopped using Jev alone, and what I pair it with now
5. How I turned 4,500 YouTube comments into a searchable audience dashboard for almost nothing
6. The real-time app I built in an afternoon that shows something surprising about Jev’s speed
7. Why Jev’s pricing model is different from any LLM I’ve used, and what it makes practical to build
8. The ChatPRD product insights project: 1,100 signals, 200,000 classifications, and what it cost me
