Safety & Alignment
Build AI systems that are safe, aligned with human values, and responsible
Overview
Safety and alignment are critical competencies for GenAI engineers. This module covers the technical and ethical foundations needed to build AI systems that behave reliably, resist adversarial attacks, and respect human values. These topics are increasingly important in interviews as companies prioritize responsible AI development.
Why This Matters for Interviews
Safety questions assess whether you can build production systems that won't harm users or create liability. Expect questions on guardrails implementation, content moderation architecture, and responsible AI principles.
Learning Objectives
After completing this module, you will be able to:
- Articulate near-term and long-term AI safety risks and mitigation strategies
- Implement content filtering pipelines with toxicity detection and PII handling
- Design and deploy guardrails using NeMo Guardrails and Guardrails AI
- Conduct systematic red teaming and adversarial testing of LLM systems
- Explain Constitutional AI and its advantages over traditional RLHF
- Apply responsible AI principles: fairness, transparency, and accountability

Prerequisites
Before starting this module, ensure familiarity with:
- LLM fundamentals (tokenization, inference, fine-tuning)
- Prompt engineering basics
- Python programming
- Basic ML concepts (classification, evaluation metrics)
Quick Reference: Safety Checklist
Use this checklist when designing safe LLM systems:
| Stage | Check |
|---|---|
| Input | PII detection, toxicity screening, injection prevention |
| Processing | Guardrails active, token limits enforced, rate limiting |
| Output | Content filtering, hallucination checks, citation validation |
| Monitoring | Logging enabled, anomaly detection, human review queue |
| Governance | Model card published, bias testing complete, audit trail |
