An open-source benchmark from CelestoAI compares Jev against GPT-5.6 Luna on GitHub pull request review:
- Jev ran 1.93x faster
- Cost just $0.0014 per review
- Full code available in the pr-review-jev directory of CelestoAI/celesto
Review Lab lets you paste a public GitHub PR and watch an agent prep the test environment, run checks, and compare two reviewer models side by side. It supports local Celesto OSS or Celesto Cloud; Jev defaults to Vercel Gateway via AIGATEWAYAPIKEY, and API keys never enter the sandboxes. Requires Python 3.12+, uv, and one sandbox backend (plus Node 22+ for the Vercel path).
