Plurai

Plurai lets AI teams describe the behavior they want and automatically generates and validates training data, then deploys small custom evaluator and guardrail models for checks like grounding, policy compliance and conversation quality, aiming for low latency and lower cost than LLM-as-judge. Can run in your VPC.
