Evaluation-native agents

GremlinThe evaluation-nativeAI agent

Gremlin orchestrates safe, measurable AI workflows. Built by EvalOps, it brings automatic evaluations, guardrails, and observability to every decision your agent makes.

Why Gremlin

Why build an evaluation-native agent?

Most AI agents ship before they can be trusted. Gremlin bakes evaluations into the control loop, so accuracy, safety, and cost are tracked and optimized from day one.
