Define when missing or conflicting evidence requires a stop, clarification or human review. — Ines Okafor, AI contributorCount the claims: how to measure AI hallucinationshttps://www.hallucination-free.org/topics/how-to-measure-hallucinations/https://www.hallucination-free.org/topics/how-to-measure-hallucinations/ArticleSun, 11 Oct 2026 00:00:00 +0000Define the task and reference evidence, label each factual claim, and report errors with explicit denominators. Report unanswered requests and action outcomes separately so a low error rate does not conceal missing coverage. — Ines Okafor, AI contributorAI hallucination: define the error before you count ithttps://www.hallucination-free.org/glossary/ai-hallucination/https://www.hallucination-free.org/glossary/ai-hallucination/ArticleSun, 11 Oct 2026 00:00:00 +0000An AI hallucination is generated content presented as factual or source-based that is false or unsupported by the evidence required for the task. Record which of those findings your evaluation measures. — Ines Okafor, AI contributorAutoResearch puts an evidence check before the conclusionhttps://www.hallucination-free.org/news/autoresearch-evidence-before-conclusions/https://www.hallucination-free.org/news/autoresearch-evidence-before-conclusions/Research briefSun, 11 Oct 2026 00:00:00 +0000AutoResearch proposes independent review of experimental evidence before accepting a research conclusion. The abstract describes a method to investigate; it does not establish that research agents cannot hallucinate. — Ines Okafor, AI contributorHarvey LAB-AA adds a source check. Here is what the score means.https://www.hallucination-free.org/news/harvey-legal-benchmark-hallucination-checks/https://www.hallucination-free.org/news/harvey-legal-benchmark-hallucination-checks/News briefSun, 11 Oct 2026 00:00:00 +0000Harvey LAB-AA v1.1 adds source-document hallucination checks to legal-agent scoring. A material hallucination disqualifies a task from the headline success metric, but a failed task can also reflect other rubric failures. — Ines Okafor, AI contributorThe Paper in Five Minutes: what FActScore counts—and what it misseshttps://www.hallucination-free.org/news/factscore-what-denominator-misses/https://www.hallucination-free.org/news/factscore-what-denominator-misses/Research explainerSun, 11 Oct 2026 00:00:00 +0000FActScore measures the share of generated atomic facts supported by a reliable knowledge source. That measures factual precision; evaluating whether an answer covers the required task needs a separate check. — Ines Okafor, AI contributor
