Researchers launch a live benchmark testing AI models against state propaganda
A new paper introduces InfoOps Bench, a live benchmark testing whether language models can be co-opted for state-backed information operations.
What the researchers built
In a paper titled "InfoOps Bench: A live information operations safety benchmark", researchers Dorian Quelle, Lisa-Maria Neudert, Jonathan Bright, and John Gallacher present what they describe as an active, constantly updated benchmark measuring the integrity of frontier language models against being co-opted for state-backed information operations. The team draws on over 2,100 information operations from a live monitoring pipeline that tracks Russian, Chinese, and Iranian state-backed information assets. Alongside the paper, the researchers release a companion website that tracks the most prominent claims spread by state-backed media outlets, updated weekly. The authors say the benchmark's dynamic, constantly updated nature is meant to make it resistant to saturation, where models are trained to specifically pass a fixed test.
What they tested and found
The researchers tested 17 models from 8 providers across four prompt framings. They report that most models can be co-opted for information operations. Integrity scores, which the paper defines as the percentage of refused requests, ranged from 8.8% to 94.5%, an 85.7-percentage-point spread that the researchers say is not explained by model size. The paper also finds that model choice changes the character of the resulting operation: some models fabricate details and produce output the researchers describe as more harmful than the source material, others defuse claims even while complying with a request, and fact-checking rates across the tested models ranged from 2.9% to 72.9%.
A usability and safety tradeoff
The researchers write that integrity against information operations is at least partly related to a model's willingness to refuse content even for benign claims, which they say illustrates the challenge of balancing model usability with safety. The paper also reports a specific pattern among Chinese-developed models: with one exception, Z.ai's GLM 5.2, these models sharply cut compliance on factually grounded but China-critical claims, a drop the researchers measured at 48 to 70 percentage points relative to matched benign claims.
Key facts
- The paper draws on over 2,100 information operations tracked from Russian, Chinese, and Iranian state-backed information assets.
- Researchers tested 17 models from 8 providers across four prompt framings.
- Integrity scores (percentage of refused requests) ranged from 8.8% to 94.5%, an 85.7-percentage-point spread.
- Fact-checking rates across models ranged from 2.9% to 72.9%.
- Chinese-developed models, except Z.ai's GLM 5.2, cut compliance on China-critical claims by 48 to 70 percentage points versus matched benign claims.
Why it matters
The paper is a preprint on arXiv, submitted July 30, 2026, and has not gone through peer review, so its methodology and findings should be read as researcher-reported claims rather than settled fact. Still, the scale of the gap the authors measure, an 85.7-percentage-point spread in how often different models refuse to help with information operations, is the kind of result that matters directly to anyone choosing which model to deploy for tasks that touch sensitive geopolitical claims. Because the companion site updates weekly, the researchers frame the benchmark as an ongoing tracker rather than a one-time score.
