Episode 32 — Hallucinations & Factuality

Large language models frequently generate outputs that sound convincing but are factually incorrect, a phenomenon known as hallucination. This episode introduces hallucinations as systemic errors arising from statistical prediction rather than true reasoning. Factuality, in contrast, refers to the grounding of AI outputs in verifiable evidence. Learners explore why hallucinations matter for trust, compliance, and user safety, particularly in sensitive sectors such as healthcare, education, and law.Case examples illustrate hallucinations producing fabricated legal citations, inaccurate medical advice, or misleading news summaries. Mitigation strategies include retrieval-augmented generation, where outputs are linked to trusted sources, automated fact-checking systems, and human-in-the-loop validation. Learners also examine transparency practices, such as source citation and confidence disclosure, that help manage user expectations. While hallucinations cannot yet be fully eliminated, layered defenses reduce their frequency and impact. By mastering these techniques, learners gain practical skills to improve accuracy and reliability of generative AI outputs.
