NVIDIA NeMo Guardrails
When OpenAI Moderation taxonomy is not enough and you need programmable rails. Host Llama Guard on Groq for the cheap classifier leaf. Strengths: Programmable Colang/rails policy engine; Composes with Llama Guard / NIM models; Serious production guardrail toolkit.
Strengths
- Programmable Colang/rails policy engine
- Composes with Llama Guard / NIM models
- Serious production guardrail toolkit
Weaknesses
- Ops-heavy vs free OpenAI Moderation
- DX steeper than drop-in classifiers
- Hosted packaging split across NIM/microservices
Galileo
Pick for production hallucination measurement + guardrails. Braintrust/Promptfoo for lighter eval loops. Strengths: Strong eval metrics research; Guardrails loop; Generous free traces.
Strengths
- Strong eval metrics research
- Guardrails loop
- Generous free traces
Weaknesses
- Enterprise features sales-gated
- Hard to size ROI without sales
- Heavier than Promptfoo
