TL;DR · WeSearch summary

Building multi-agent AI systems on AWS faces challenges with state transfer due to payload limits in services like Step Functions and DynamoDB. By using AWS Lambda mounted with Amazon EFS, AI agents can share and access large contexts in real time through a POSIX-compliant file system. This approach reduces latency, bypasses size constraints, and lowers costs compared to traditional storage methods.

Key facts

▪AWS Step Functions has a 256KB payload limit, which restricts multi-agent AI state sharing.
▪Amazon EFS allows Lambda functions to share a file system, enabling real-time streaming of AI-generated content between agents.
▪Using EFS avoids high DynamoDB write costs and S3 latency by providing low-latency, byte-level file access for large AI workloads.

In a multi-agent framework, AI agents are constantly reading, writing, and debating over a shared context. Agent A (The Researcher) reads 50 pages of documentation.
