   AWS introduces Amazon Bedrock AgentCore Evaluations

   AWS Machine Learning Blog introduced Amazon Bedrock AgentCore Evaluations, combining AWS-built-in evaluators with DeepEval and AutoEval metrics for measuring AI-agent behavior. The service supports on-demand evaluation for direct session testing, online evaluation of sampled production traffic, and batch evaluation against fixed session datasets, while also offering custom LLM-as-a-judge evaluators. AWS states that its built-in evaluators are quality-tested and benchmarked for reliability, though the evidence comes from the vendor's own tutorial.

   AWS tutorial connects decision models to AgentCore Evaluations

   AWS Machine Learning Blog published a tutorial showing how to connect Jev and Strands Decider 2B to Amazon Bedrock AgentCore Evaluations through code-based evaluators. The sample converts OpenTelemetry trace and session data into model requests, then maps calibrated probabilities back to groundedness, helpfulness and goal-completion results. AWS says the decision models can run alongside 15 built-in evaluators, custom LLM-as-a-judge evaluators and deterministic checks.
