## Summary

The post explains how to use Amazon S3 Vectors as a persistent memory layer in NVIDIA NeMo Agent Toolkit (NAT). It walks through creating a vector bucket, implementing a custom MemoryEditor plugin, and configuring NAT to use the plugin. The tutorial targets teams running NAT on Amazon EKS and using Amazon Titan Text Embeddings V2 for vector generation.

The article lists prerequisites: an AWS account with S3 Vectors and EKS permissions, an existing EKS cluster, NAT 1.6, Python 3.11/3.12, and the embedding model. It then details three steps: set up the S3 Vectors infrastructure, build the MemoryEditor plugin, and wire the plugin into NAT’s YAML config with the automemoryagent wrapper. It also covers IAM roles, Docker images, and Kubernetes manifests.

The author discusses responsible AI considerations, such as retention policies, PII handling, and least‑privilege IAM scopes. It ends with a multi‑agent investment research use case that shows how shared memory reduces duplicate work and improves groundedness. The tutorial concludes with cleanup instructions to avoid ongoing charges.

## Key points

- Amazon S3 Vectors can serve as a persistent memory backend for NVIDIA NeMo Agent Toolkit on Amazon EKS.
- The tutorial requires NAT 1.6, Python 3.11/3.12, Amazon Titan Text Embeddings V2, and an existing EKS cluster.
- Using the automemoryagent wrapper, agents automatically capture and retrieve memory, reducing duplicate work and improving groundedness.

## Why it matters

Enabling persistent memory in multi‑agent systems lets agents share context, cut redundant API calls, and improve answer quality. Using Amazon S3 Vectors gives strong consistency and elastic scaling, making it practical for production deployments on EKS. This approach supports scalable, cost‑efficient agent workflows across industries.
