What you’ll find in the video

  1. The playground sets instructions and criteria for binary probabilities, category choices, and ordered scores.
  2. The setup configures a coding-assistant integration with a project API key before building the demo.
  3. The email-triage prototype uses structured questions and routing decisions; it does not authenticate a live mailbox or establish real-mail accuracy.
Worth knowing

Gemini-assisted video/transcript review. The email triage application relies on a synthetic batch demo without live mailbox auth, and Jev is an intuitive decision classifier rather than a generative text or deep reasoning LLM.
