AWS re:Invent 2025: Frontier AI agents replace chatbots

At AWS re:Invent 2025, the focus has shifted from chatbots to "frontier AI agents" capable of autonomous, long-duration task execution, signaling a move beyond simple conversational interfaces toward more complex, operational AI systems. To address the significant infrastructure challenges associated with deploying these agents at scale, AWS introduced Amazon Bedrock AgentCore, a managed service that functions as an operating system for AI agents, streamlining backend processes such as state management and context retrieval. This development aims to reduce the engineering complexity traditionally involved in building and maintaining frontier AI agents, enabling organizations like MongoDB to significantly accelerate
