Jev founder publishes PDF on building a Jev harness, claiming 200x speed and 400x cost gains
Diogo Amogo's PDF explains how to rebuild an existing coding agent as a Jev harness, with tests showing up to 200x faster and 400x cheaper results, and it can be handed to Claude Code or Codex to follow.
this is pure f*cking gold for anyone running coding agents Jev founder Diogo Amogo wrote a PDF on building a Jev harness what their tests show: > up to 200x faster > up to 400x cheaper the model hasn't been the bottleneck for a while speed and cost both come from the harness you wrap around it • how to use it > give this PDF and the article below to Claude Code or Codex > ask it to rebuild its own setup around Jev • how it turns into a promotion > pick the agent workflow your team pays the most for > rebuild it in one evening > bring the before and after bill to your manager one evening of Jev engineering, and next week you're the one running a harness most teams haven't built yet
