Responsible AI
Bias, hallucinations, privacy, and human oversight for production AI
Overview
Responsible AI means building systems that are fair, safe, transparent, and respectful of user privacy. LLMs inherit biases from training data, can hallucinate confident falsehoods, and may leak sensitive information if prompts or logs are mishandled. Production apps need policies, technical controls, and human oversight—not just a disclaimer.
Developers share responsibility with product and legal teams, but you implement the guardrails: data handling, access control, evaluation, and escalation paths.
Syntax / Usage
Risk areas and mitigations:
| Risk | Mitigation |
|---|---|
| Hallucinations | RAG with citations, require sources, validate facts for high-stakes domains |
| Bias / harm | Testimonial test sets, diverse eval data, content filters, blocklists |
| Privacy | Minimize PII in prompts, redact logs, regional data residency, retention limits |
| Prompt injection | Separate instructions from user content; never execute model output as code blindly |
| Over-reliance | Human review for medical, legal, financial decisions; clear UX that AI can err |
Data handling checklist:
□ Classify data sent to third-party APIs (PII, secrets, regulated)
□ Use enterprise agreements / zero-retention options where required
□ Encrypt in transit (HTTPS) and at rest
□ Document what is logged and for how long
□ Provide opt-out and deletion where applicable (GDPR, etc.)
Examples
Safe logging wrapper:
function sanitizeForLog(text: string): string {
return text
.replace(/\b[\w.-]+@[\w.-]+\.\w+\b/g, "[EMAIL]")
.replace(/\bsk-[A-Za-z0-9]+\b/g, "[API_KEY]");
}
User-facing disclosure:
"This answer is AI-generated and may contain errors. Verify important information."
Maintain an eval set of prompts with expected behavior (refusals, tone, factual grounding) and run it on prompt or model changes. Escalate to humans when confidence is low or the topic is on a restricted list.
Common Mistakes
- Sending customer data to public APIs without legal review
- No way to report or correct harmful outputs
- Treating AI output as authoritative in regulated workflows
- Storing full chat histories indefinitely without purpose limitation
- Ignoring accessibility and clarity—users must understand when they interact with AI
