Part 8/12:

• Implement access controls, identity management, and response vetting.

• Guardrails include prompt injection safeguards, hallucination detection, and hallucination mitigation.

• Monitoring system behavior at each stage helps detect anomalies early and prevent vulnerabilities.

Best Practices for Ground Truth and Data Construction

Building reliable ground truth data remains a core challenge, especially with scarce or domain-specific data:

• Synthetic data generation: Use LLMs to produce initial annotations and responses.

• Human-in-the-loop annotation: Augment synthetic data with targeted human review.

• Iterative refinement: Start small, validate responses, and expand over time.
