SynthArbiter: Autonomous Ethical AI Agent
Inspiration
In an era where AI systems are becoming increasingly autonomous and capable, ethical decision-making becomes paramount. SynthArbiter was born from the need to address complex ethical dilemmas in emerging fields like synthetic consciousness, neural organoids, and advanced AI systems. Traditional ethical frameworks often fail to provide clear guidance for unprecedented technological scenarios. We envisioned an AI system that could reason through these dilemmas using established philosophical frameworks while incorporating real-time context from ethical literature and historical precedents.
What it does
SynthArbiter is an autonomous ethical AI agent that analyzes complex dilemmas in synthetic consciousness and advanced AI systems. Users submit ethical scenarios, and the system provides reasoned recommendations using multiple philosophical frameworks.
Core Capabilities:
- Multi-Framework Analysis: Utilitarian, deontological, and virtue ethics perspectives
- Retrieval-Augmented Generation (RAG): Semantic search through ethical literature and precedents
- Content Safety: Built-in moderation using NVIDIA NeMo Guardrails
- Real-time Reasoning: Powered by NVIDIA NIM Llama 3.1 Nemotron Nano 8B
- Vector Search: OpenSearch k-NN for semantic similarity matching
The system processes scenarios like "Should a learning neural organoid be granted legal personhood?" and returns structured analyses with reasoning steps, recommendations, and quality evaluations.
How we built it
SynthArbiter is a complete serverless AI platform deployed on AWS using automated CI/CD.
AI/ML Infrastructure:
- NVIDIA NIM Microservices: Three production-grade AI models on SageMaker endpoints
- NIM Reasoning (Llama 3.1 Nemotron Nano 8B) for ethical analysis
- NIM Embedding (E5-v5) for vector generation
- NIM Guardrails for content safety
- OpenSearch: k-NN vector database for semantic search
- AWS Lambda: Orchestration layer for the analysis pipeline
Cloud Architecture:
- 4-Layered CloudFormation: Network, Storage, Frontend, and NIM Microservices stacks
- VPC-secured: All AI endpoints in private subnets with VPC endpoints
- Automated Deployment: GitHub Actions CI/CD with ECR image management
- Frontend: Amplify-hosted static website with Cognito authentication
RAG Pipeline:
- User submits ethical scenario
- NIM Embedding generates semantic vectors
- OpenSearch performs k-NN similarity search for relevant precedents
- Context-enriched prompts sent to NIM Reasoning for analysis
- NIM Guardrails validates output safety
- Results stored in DynamoDB with evaluation metrics
Challenges we ran into
SageMaker Endpoint Health Checks:
NIM containers required port 8080 for SageMaker health checks, requiring environment variable configuration and VPC endpoint setup.
ECR Image Management:
Pulling large NIM containers (8-20GB) within CI/CD time limits required custom ECR push logic with disk space management and image caching.
VPC Repository Access Mode:
SageMaker models needed specific configuration for ECR access within VPC, involving VPC endpoints and authentication setup.
Circular Dependencies:
CloudFormation stack dependencies created circular references between Lambda functions and SageMaker endpoints, resolved through careful resource ordering.
Container Startup Times:
NIM model loading required 10+ minutes, necessitating extended health check timeouts and proper environment configuration.
Accomplishments that we're proud of
Complete Production-Ready Platform:
Built a full-stack AI ethics analysis system from ideation to deployment in a hackathon timeframe, including automated CI/CD, monitoring, and security.
Advanced AI Architecture:
Successfully integrated three NVIDIA NIM microservices with RAG, creating a sophisticated ethical reasoning system that outperforms basic AI approaches.
Automated Infrastructure:
Implemented a 4-layer CloudFormation deployment with ECR image management, VPC security, and automated website deployment - production-grade infrastructure as code.
Scalable RAG System:
Built a semantic search system using OpenSearch k-NN that enhances AI reasoning with relevant ethical context, demonstrating practical RAG implementation.
NVIDIA Integration:
Successfully deployed and integrated multiple NVIDIA NIM microservices on SageMaker, showcasing enterprise-grade AI deployment patterns.
What we learned
NIM Microservices Complexity:
NVIDIA NIM provides production-ready AI models but requires careful configuration of ports, environment variables, and VPC access patterns.
RAG Implementation:
Retrieval-augmented generation significantly improves AI reasoning quality, especially for domain-specific tasks like ethical analysis.
CloudFormation Layering:
Multi-stack CloudFormation deployments require careful dependency management and resource sharing through exports/imports.
CI/CD for AI:
Automated deployment of AI models requires special handling for large container images and model caching strategies.
Ethical AI Development:
Building AI for ethical reasoning revealed the complexity of translating philosophical frameworks into computational approaches.
