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.

Yes / noDid the agent run meet the evaluation criterion?(inferred)yes · no

How it works

  1. Collect agent traces
  2. Judge them with Jev and with LLM judges
  3. Compare accuracy, repeatability, latency and cost
