Summary
This video walks through building an agentic operating system that pairs Anthropic’s Claude with Jev, a fast and inexpensive decision model. Creator Jack Roberts shows Jev acting as a routing layer: it classifies incoming messages (buyer, question, praise, criticism or spam) in under a second, then decides whether a request should go to a simple web search, Codex or Claude.
The demo covers several practical use cases inside the OS. Jev sorts a sample inbox into replies, newsletters, billing, community leads, sponsors and FYI in real time. A voice assistant answers questions such as remaining Claude usage and how Jev’s speed compares with Claude Opus 5.5, with the creator claiming Jev is roughly 20% faster on some tests and about 40% cheaper than comparable models. Text-to-speech settings and voice selection are shown for customizing the assistant.
The final section focuses on short-form content. Roberts uses Opus 5.5 to generate graphics for Instagram Reels and YouTube Shorts, then shows how a reel workflow can clean up audio and add sound effects. Viewers interested in agent design, model routing, voice interfaces and low-cost automation will find concrete ideas for combining a small decision model with a larger reasoning model.
