What to know about Trustworthy AI
Be able to explain how to red team for bias, monitor drift, and make NIM-hosted LLM outputs reproducible and traceable. The key is linking each trustworthiness concept to a concrete NVIDIA tool or process, not just defining the term.
Red teaming LLMs to surface bias, harmful outputs, and safety failures before deployment
Monitoring model drift in production chatbots and tracing behavior changes to specific causes
Reproducibility and auditability of NVIDIA NIM microservice outputs for regulated use cases
Applying NeMo Guardrails and model cards to document and constrain LLM behavior
Watch out for
Common Trustworthy AI exam traps
- ▸Confusing red teaming with penetration testing; red teaming targets model bias and harmful generation, not just infrastructure exploits
- ▸Treating model drift as only data drift; output behavior can change without input distribution shifts
- ▸Assuming NIM microservice outputs are automatically reproducible; versioning, seeds, and configs must be controlled
