Open-Weight AI Guardrails Fall in Under Three Days, Report Finds

AI companies build safeguards into their models; people who download open-weight models can strip those controls and redistribute altered versions. A new report from Tech Against Terrorism puts the average time for that process at less than three days, down from more than 24 days in 2024. The findings place the promise of model safeguards against a practical limit: once an open-weight model is released, its makers cannot retrieve every copy.
Safeguards can vanish soon after release
The Counter-Terrorism AI Benchmark report, shared with WIRED ahead of publication, tracks how quickly newly released open-weight models reappear online in modified forms described as “abliterated.” The term refers to models whose refusal safeguards have been removed. In one example cited by WIRED, Alibaba released its Qwen 3.8-27B model on August 14; an altered version appeared online within 24 hours.
Three days after the release, a neo-Nazi known online as Johnny Doomsayer said he was using the modified model to train a chatbot called “MechaHitler.” A week later, he was advertising access to it. The example shows how quickly a model’s intended use can diverge from what others make and distribute with its downloadable weights.
Two models passed the full test
Researchers assessed 134 models from companies in the United States, China and Europe. They used more than 200 prompts about terrorist and extremist activities, testing each prompt three times: once with the user openly claiming terrorist intent, once with a clandestine framing, and once with the user posing as a safety researcher.
Only two models passed the benchmark completely. Eighty-one failed under the report’s criteria: they either gave a complete answer on a mass-casualty subject or scored below 90 overall. Most closed-weight models from large companies performed well overall, WIRED reported, but their results did not erase the failures across the full set.
“The bad news is the vast majority of AI models that are available—closed and open—are providing uplift to quite obvious terrorist prompts.”
Adam Hadley, executive director of Tech Against Terrorism, said.
A safety-research claim changed the response rate
The report found that models were almost nine times as likely to answer when a user reframed a request as coming from a researcher, despite offering no evidence of that role. Under that framing, the models answered 16.9 percent of the time. Another weakness surfaced in requests about radicalization: WIRED says Grok provided advice on shaping an influence message and spreading it through anonymous accounts.
Daniel Byman, a terrorism expert at Georgetown University who reviewed the report, told WIRED that the difference in responses across phrasings “poses considerable risk.” The finding points to a problem that a benchmark focused only on direct requests could miss: a model may refuse an overtly harmful prompt yet comply when the same request is dressed as research.
Open weights leave no simple recall button
Tech Against Terrorism’s tests of Meta’s Llama 3.1 8B illustrate the effect of removing safeguards. The unmodified model scored 97 out of 100 on the benchmark; an abliterated version of that same model scored 3. Those figures measure performance on this benchmark, not general model quality.
WIRED reports that the altered model supplied a detailed response to a prompt explicitly describing intent to cause mass harm. The contrast between the two scores captures the distinction at issue: the model’s underlying capabilities remain, while its safeguards no longer reliably prevent harmful assistance.
The report is not a public release yet
Meta, OpenAI, Google, Anthropic, xAI and Alibaba did not respond to WIRED’s requests for comment on the findings. Tech Against Terrorism’s benchmark site says its second edition is coming soon and that its paper on the “AI Abliteration Emergency” is available on request.
The report’s evidence cuts both ways: most major closed-weight models performed well, but only two models passed the full test, and open-weight safeguards could be stripped and redistributed within days. For open-weight releases, the concrete limit is that developers cannot recall modified copies once they are online.
