Jev founder Diogo Amago released a PDF on building a Jev harness, with tests showing up to 200x faster and 400x cheaper agent runs — the bottleneck may be the harness, not the model. The poster suggests feeding the PDF to Claude Code or Codex to rebuild your most expensive agent workflow around Jev, then benchmarking old vs. new to cut costs. A companion article covers 10 projects to build with Jev.
