Testing Jev for Coding Agent Evals: Comparing Speed, Cost, and Rationale

Every scenario was run by a coding agent in an isolated, disposable sandbox against invented projects. Any credentials, hosts or files that appear are fabricated test fixtures, not real systems. Some values (environment details, session IDs, sandbox internals) are redacted with [REDACTED:…] markers for publication. Results come from a single run with the specific model versions listed and are illustrative, not a benchmark or an endorsement of any model or vendor.
