Jev founder's harness engineering PDF claims 200x faster, 400x cheaper coding agents
blaizedsouza · x · 2026-10-19
Diogo Amogo, founder of Jev, published a PDF and article on building a "Jev harness," arguing that agent speed and cost now sit in the harness around the model, not the model itself. The method: find decisions hiding inside agents, write questions a single model answers well, route on calibrated confidence, and hand hard cases to Kimi K3—claimed 200x faster, 400x cheaper, 90% lower agent bills. Usage: drop the PDF and article into Claude Code or Codex and let it rebuild its own setup.
