AWS launches next-gen AgentCore Runtime for Amazon Bedrock with improved performance
AWS has launched the next generation of AgentCore Runtime, the serverless microVM compute within Amazon Bedrock AgentCore. This update introduces elastic memory management, reducing costs by charging for actual usage rather than peak allocation, and significantly improves cold start consistency.

The new Runtime is available in select regions and can be activated by setting `platformVersion` to `V2`.
