AWS launches Bedrock AgentCore evaluations
What happened
On 5 October 2026, the AWS Machine Learning Blog published an article introducing Amazon Bedrock AgentCore Evaluations, a capability for assessing the explainability and usefulness of multi-agent systems. It supports built-in and custom evaluators: built-in evaluators cover general dimensions such as helpfulness, task success and instruction following, while custom evaluators can check decision rationale, data citations and trade-offs such as cost and service levels, treating explainability as a first-class evaluation dimension. The capability supports two modes: an on-demand mode for development benchmarks and CI/CD gates, and an online mode for continuous monitoring and alerting in production. The report does not mention earlier versions or previous releases.

- AWS Machine Learning BlogEvaluating multi-agent systems for explainability and helpfulness with Amazon Bedrock AgentCore
Multi-agent systems need deeper guarantees than fluent responses: they must select the right tools, respect constraints, and explain their decisions. Learn how to build a Strands-based multi-agent supply chain decisioning system and evaluate it with Amazon Bedrock AgentCore Evaluations using built-in, custom, and explainability evaluators.
