Jev Founder Publishes Coding Agent Harness Guide Claiming 200x Speed, 400x Cost Cut

- Jev founder Diogo Amogo released a PDF blueprint for building a "Jev Harness" for coding agents, claiming 200× faster and 400× cheaper agent workflows.
- The accompanying article says Jev launched at $0.042 per million tokens with free output, explains why its cost math "runs backwards," and details a request pattern that's 12.2× more efficient, with exact configs included.
- The author suggests feeding the PDF and article straight into a Claude Code or Codex instance to replicate the setup. Treat the numbers as unverified vendor claims.
