Amazon announced the multi-agent collaboration capability for Amazon Bedrock (preview). This allows developers to build, deploy, and manage multiple specialized agents working together seamlessly to tackle more intricate, multi-step workflows. Managing multiple agents for complex tasks can be challenging with open-source solutions, requiring manual implementation of orchestration, session handling, and memory management. Amazon Bedrock's fully managed multi-agent collaboration simplifies this by having a supervisor agent coordinate specialized sub-agents. The supervisor breaks down requests, delegates tasks, and consolidates outputs. For example, an investment advisory system could have agents for financial analysis, research, forecasting, and recommendations. A retail system could handle demand forecasting, inventory, supply chain, and pricing. Amazon Bedrock manages the collaboration behind the scenes, leading to higher task success rates, accuracy, and productivity. Internal tests show significant improvements over single-agent systems for complex tasks. Key features include quick setup, composability with existing agents, efficient inter-agent communication, optimized collaboration modes (supervisor and supervisor with routing), and an integrated trace and debug console. These features improve coordination, communication speed, and overall effectiveness. The announcement includes a demo of creating a social media campaign manager agent with sub-agents for content strategy and engagement prediction. The demo walks through creating sub-agents, a supervisor agent, and associating them. It highlights the ability to choose between supervisor mode and supervisor with routing mode, and the option to enable conversation history sharing. During the preview, multi-agent collaboration supports real-time chat assistant use cases, and sub-agents can have collaboration enabled with a soft limit of three hierarchical agent team layers. The feature is available in preview in all AWS Regions that support Amazon Bedrock Agents, except AWS GovCloud (US-West).
