VeriTaS: A Living Benchmark for Multimodal Fact-Checking

14 Jan 2026 — 1 min read

Misinformation is growing fast, but today’s AI fact-checkers are often graded on outdated, static tests that leak into model pretraining—making scores look better than real-world performance.

VeriTaS is a living benchmark for automated fact-checking across text, images, and video. It stays fresh and robust, so evaluations actually mean something.

24,000 real claims from 108 fact-checking orgs, spanning 54 languages
Multimodal: textual and audiovisual content
Quarterly updates via a 7‑stage pipeline that normalizes claims, fetches original media, and maps expert verdicts to a clear, disentangled scoring scheme with explanations
Human evaluations show automated labels closely match expert judgments
Open data and code; designed to resist pretraining leakage

For researchers, journalists, and industry: use VeriTaS to test AFC systems against the world as it is—now and tomorrow. More: https://arxiv.org/abs/2601.08611

Meet GRACE: a moral governor for safer, more transparent AI

AI agents are getting powerful—so how do we make sure they do the right thing, not just the effective thing? Meet GRACE, a reason-based moral governor that keeps AI behavior aligned with human norms by separating moral reasoning from goal-driven decision-making. * Moral Module: uses deontic logic and explicit reasons

Why some fine-tuned LLMs miss phishing—and how to fix it

Not all fine-tuned LLMs spot phishing equally. A new study tests Llama 3.1 8B, Gemma 2 9B, and Mistral on high-stakes phishing detection—and uses SHAP and mechanistic interpretability to reveal why models do (or don’t) generalize. * Architecture × data diversity matters: Gemma 2 9B hits state-of-the-art performance (F1

AI that explains itself—by following the science

AI that explains itself—by following the science Black-box AI can be powerful, but it often can’t tell us why it made a decision. Concept Bottleneck Models (CBMs) try to fix that by predicting human-understandable concepts first, then the final answer. The catch: standard CBMs ignore domain-specific cause-and-effect and

Meet GenomAgent: A Team of AI Specialists for Smarter Genomics Q&A

TL;DR: Finding reliable answers in genomics is hard. GenomAgent turns one big AI into a coordinating team of specialists—and beats the current leader by 12% on a key benchmark. Genomic facts live across many databases. Standard chatbots struggle because they can’t flexibly query those sources. GeneGPT added
