This summary is based on how curated lists describe the project; its README was not available to review.
Overview
A LangChain blog post comparing Jev with LLM-as-judge setups for evaluating agents in LangSmith, on accuracy, repeatability, latency and cost.
Per the listing, it concludes Jev is the cheaper and more consistent judge for online evaluations.
