Eval Engineering Platform turns AI evaluation results into automated production guardrails.
The platform builds evaluation datasets from synthetic, development, and live production data, capturing subject-matter-expert annotations to ground AI systems continuously. Development teams use more than twenty prebuilt evaluators for retrieval-augmented generation, agents, safety, and security, alongside custom evaluators for domain-specific needs.
Optimized evaluations are distilled into compact models that monitor production traffic at high volume and lower cost than large language model judges. An insights engine analyzes evaluation results to help engineering teams identify and fix issues before deployment.
