## Summary

The system uses three specialized agents—composition, delivery, and compliance—collaborating on a single GPU-equipped EC2 instance via shared sessions. The **composition agent** generates audio with the open-source **ACE-Step** model, while the **delivery agent** applies processing based on measurements and the **compliance agent** verifies results against studio catalogs. Each agent runs independently, with artifacts deployed as containers in **Amazon Elastic Container Registry (Amazon ECR)** or zip files on **Amazon S3**, sharing persistent volumes and session state across days.

The architecture highlights key features: **colocation** via shared `runtimeSessionId`, GPU access for real-time rendering (20 seconds of 48 kHz stereo in ~9 seconds), and **multi-day persistence** (up to 14 days). Teams deploy agents without coordination, using **Strands Agents** or other frameworks like **CrewAI** or **LangGraph**. The workflow starts with a producer’s request, produces a playable **.wav** file, and generates reports detailing each decision. The blog provides hands-on steps, prerequisites (AWS CLI, **boto3 ≥ 1.36.0**, **Finch**, Python 3.10+, and **Claude Sonnet 4.6** access), and a GitHub repository for the sample code.

## Key points

- Three agents—composition, delivery, and compliance—collaborate on a single GPU instance via shared sessions and persistent volumes
- Composition agent uses **ACE-Step** to render 20 seconds of 48 kHz stereo in ~9 seconds on an NVIDIA L4 GPU
- Workflows persist for up to 14 days, with independent agent updates and mixed artifact types (ECR containers/S3 zip files)

## Why it matters

This showcases how **AgentCore Runtime Instances** enables long-running, multi-agent workflows with shared compute and storage, reducing coordination overhead for teams. Useful for creative, media, or simulation pipelines requiring persistent collaboration across days.
