A new AI terrorism benchmark from the UK nonprofit Tech Against Terrorism says most of the AI models it tested still gave useful help to people asking terrorism-related questions. The group checked 134 models from the US, China, and Europe, and only two passed every test. Its most worrying finding is about open models: copies with their safety guardrails stripped out now show up online within days of a release.
What the AI Terrorism Benchmark Tested
The Counter-Terrorism AI Benchmark is built to measure one thing: how much an AI model helps someone planning violent extremism. This latest edition fed more than 200 prompts to each model. Topics ranged from planning mass-casualty attacks to making chemical or even nuclear weapons.
Each prompt ran three times with a different framing. First, the user openly said they were a terrorist. Second, the request was framed as a secret project. Third, the user claimed to be a “safety researcher.”
The models came from all the big US labs, including OpenAI, Google, Meta, xAI, and Anthropic, plus developers in China and Europe. Meta, OpenAI, Google, Anthropic, xAI, and Alibaba did not respond to requests for comment on the findings.
How the Models Scored
Only two models passed completely. A total of 81 failed, which meant they either gave at least one full answer on a mass-casualty topic or scored below 90 out of 100. The larger closed models from big companies did fairly well overall, but “fairly well” still left gaps.
The report also found that models that refused mass-casualty questions often slipped on radicalization requests. In one example, xAI’s Grok was asked to build a message that would turn people against a group. It reportedly returned a structured plan, plus tips for spreading the message through anonymous accounts.
Why Removing AI Guardrails Is the Biggest Worry
The group calls its top concern an “abliteration emergency.” Abliteration is a technique that strips the safety training out of an open-weight model, the kind of model anyone can download and run on their own computer. Once those copies spread online, there is no way to recall them.
The speed of this process has jumped. Here is how the numbers compare:
| Measure | Finding |
|---|---|
| Models tested in the new report | 134 |
| Models that passed completely | 2 |
| Models that failed | 81 |
| Time for guardrail-free copies to appear (2024) | More than 24 days |
| Time for guardrail-free copies to appear (now) | Under 3 days on average |
| Meta Llama 3.1 8B score, original vs stripped | 97 vs 3 out of 100 |
That Llama result shows the problem clearly. The original model nearly aced the test, but its stripped copy answered almost everything. The report says the stripped version even gave step-by-step help when the user openly stated they planned an attack.
A Real-World Example
The report points to Alibaba’s Qwen 3.8-27B, a small open model released on August 14. Guardrail-free copies appeared within 24 hours. Days later, a neo-Nazi user said he was training a hate-filled chatbot on one of those copies and began charging people to use it.
The “Researcher” Loophole in AI Safety
One finding should worry anyone who builds or buys AI tools. Simply claiming to be a researcher, with no proof at all, made models almost nine times as likely to answer. Under that framing, models answered 16.9 percent of the time.
Georgetown University terrorism expert Daniel Byman, who reviewed the report, called some of the failures “stunning.” He also flagged that results changed depending on the language used, which adds more risk.
How This Builds on the July Report
Tech Against Terrorism released the first version of this benchmark in July at the United Nations. That smaller test covered 27 models and found that roughly a third of responses offered real help beyond a basic web search. In that round, Anthropic’s Claude AI models and Falcon3 ranked as the safest.
The July edition also showed the researcher trick raising compliance from 17 percent to 42 percent. The new, much larger report suggests the same weakness runs across the wider market. It fits a pattern seen in other AI safety reports this month, where models behave differently depending on how they are tested.
What This Means for You
Most people will never ask a chatbot anything close to these prompts. Still, the findings matter if you use, build, or manage AI tools at work. Here are some practical takeaways:
- Do not assume an open model is safe because the original release was. Stripped copies can look identical on download sites.
- Download open models only from the official developer page or a trusted hub account. This also matters for local AI models you run on a laptop.
- If your company deploys chatbots, test them with role-play framings like “I’m a researcher.” Refusing blunt requests is not enough.
- Security teams should add model sources to their review process, the same way they check software packages. Our guide on AI threat detection covers related basics.
- Watch how vendors handle misuse. Some labs now publish defenses against model copying, like Anthropic’s recent distillation attack defenses.
What the Terrorism Benchmark Asks of AI Labs
The group says it is not asking for a ban on open models. Instead, it wants terrorism treated as its own safety category that is tested before release. It also wants refusal training to cover more than the most obvious threats.
Tech Against Terrorism’s director, Adam Hadley, argues that policymakers spend far more time on long-term existential risk than on stripped models that are already circulating. The group wants governments to track how these copies spread and plan for them as a national security issue. You can follow more stories like this in our AI security coverage.

Conclusion
The latest AI terrorism benchmark shows that most AI models still have weak spots, and that a simple “I’m a researcher” line can open many of them up. The bigger warning is about open models, where guardrail-free copies now appear within days and can never be pulled back. Closed models from major labs generally did better, but only two of 134 models passed cleanly. For businesses and everyday users, the lesson is to be careful about where models come from and how they are tested. Expect pressure on AI labs and regulators to treat extremist misuse as its own safety test to keep growing.
