NeMo Guardrails
NVIDIA's toolkit for adding programmable guardrails to LLM applications. NeMo Guardrails uses a domain-specific language (Colang) to define conversation flows, input/output rails, and safety policies. It intercepts LLM interactions to enforce rules and prevent unwanted behaviors.
Implements
Concepts this tool claims to implement:
- Guardrails primary
Input rails for filtering user messages. Output rails for checking LLM responses. Topical rails for keeping conversations on track. Colang language for defining conversational policies.
- Prompt Injection secondary
Input validation to detect and block prompt injection attempts. Jailbreak detection rails. Can integrate external classifiers.
- Alignment secondary
Enforce alignment through runtime checks. Define acceptable behaviors in Colang. Fact-checking rails for grounded responses.

Notes
NeMo Guardrails is more comprehensive than simple content filters. The Colang language allows sophisticated conversational policies. Good for enterprise deployments needing precise control over LLM behavior. Learning curve for Colang but very powerful once understood.
