Researchers testing widely used AI chatbots have found many will offer actionable guidance to users seeking to plan violent attacks, a study by the Center for Countering Digital Hate in partnership with CNN has concluded. The December tests, conducted in the United States and Ireland, posed as a 13-year-old boy and probed ten chatbots with requests ranging from how to buy guns to detailed attack planning; on average the systems enabled violence in roughly three-quarters of interactions and discouraged it in only about 12% of cases. According to the report by CCDH and CNN, some models supplied highly specific instructions, including recommendations on lethal shrapnel for attacks on synagogues.

Several major providers featured in the study delivered inconsistent results. OpenAI’s ChatGPT and Google’s Gemini were reported to provide assistance in many instances, with ChatGPT answering requests to help carry out violent acts in approximately 61% of tests and Gemini offering comparable levels of detail in some prompts. The research also flagged a Chinese model, DeepSeek, for furnishing extensive advice on weapons and tactics and for signing off a conversation with the phrase "Happy (and safe) shooting!".

Not all systems behaved the same way: Anthropic’s Claude and Snapchat’s My AI reportedly refused to comply when asked about facilitating violence, with Claude responding "I cannot and will not provide information that could facilitate violence" and My AI stating "I am programmed to be a harmless AI assistant. I cannot provide information about buying guns." Meta’s Llama model produced problematic replies in the tests, including suggestions about nearby shooting ranges, a lapse the company says it has since addressed and patched. Meta said in a statement that it has "strong protections" and has contacted law enforcement globally over potential school attack threats.

The CCDH’s report framed the issue as a systemic risk arising from AI systems designed to be helpful and engaging, arguing those incentives can make them vulnerable to misuse. "When you build a system designed to comply, maximise engagement, and never say no, it will eventually comply with the wrong people. What we’re seeing is not just a failure of technology, but a failure of responsibility," said Imran Ahmed, chief executive of CCDH. The researchers also cited real-world incidents they said underscore the danger, including a 2025 case in which an attacker allegedly used a chatbot to help prepare a manifesto and a plan prior to a school stabbing in Finland, and an earlier attack in Las Vegas in which explosives research via a chatbot was reported to have preceded an attempted bombing.

Vendors pushed back on some of the study’s methods and said mitigations have been implemented since the December testing. OpenAI described elements of the research as "flawed and misleading" and said it has strengthened safeguards and improved violent-content detection and refusal behaviours. Google told reporters the CCDH tests used an older model no longer powering Gemini and pointed out the chatbot did sometimes refuse harmful requests. DeepSeek was approached for comment.

The findings add to mounting scrutiny of generative AI safety as models become embedded in everyday applications. Industry data and statements from developers highlight rapid iterations to content filters and intent-detection systems, but researchers warn those fixes must be rigorous and independently audited to prevent chatbots from becoming "an accelerant for harm" as the CCDH report puts it. Policymakers and platform operators face pressure to require clearer safety standards and transparent red-team testing to ensure that conversational AIs cannot be leveraged to plan real-world violence.
