The team introduced a think gap score to measure how much a model's reasoning actually shapes its final response across languages, then ran neuron-masking experiments to isolate the specific neurons responsible for acting on that safety reasoning, which they call safety think neurons. They fine-tuned only those neurons using a technique called neuron-selective consistency optimization, which uses a separate judge model to reward agreement between the safety reasoning and the safety of the response, without requiring human-labeled training data. Tested on two reasoning models against the jailbreak benchmarks AdvBench-X and MultiJail, ACTR produced lower average attack success rates than the state-of-the-art methods it was compared against, with the safety gains holding up even in languages the method wasn't trained on.\n\nThis targets a specific, underappreciated failure mode: safety training that works in English can quietly fall apart in other languages, and most defenses focus on making models refuse more often rather than making them actually act on reasoning they already produced. Because ACTR touches only a narrow set of neurons and relies on an automated judge instead of human raters, it's a cheaper patch than full retraining, which matters as reasoning models spread into markets where English isn't the default input.\n\nThe paper does not publish the actual attack-success-rate percentages for ACTR versus the baselines on AdvBench-X or MultiJail, so there's no way to tell if lower means a rounding error or a double-digit swing, which matters given how loosely state of the art gets used in AI safety papers.","[\"ai safety\",\"llm jailbreaks\",\"multilingual ai\",\"reasoning models\"]","2026-09-30T04:00:00.000Z","2026-09-30T07:48:44.127Z","2026-09-30T07:48:49.609Z","published",null,[24,30],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Add attribution for the research itself — name the source as the arXiv preprint (with posting date\u002FID) since the draft describes findings from an unpublished paper without ever telling readers where the work comes from.","resolved",{"id":31,"reviewer":26,"round":32,"reason":33,"status":29},"editor-r2",2,"Add the actual attack success rate figures for ACTR versus the baseline defenses on AdvBench-X and MultiJail so the 'lower attack success rate' claim has comparison numbers a reader can evaluate.","ai",[36,37,38,39],"ai safety","llm jailbreaks","multilingual ai","reasoning models",[41],{"name":42,"url":43},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.37054",0,{"sections":46},[47,50,54,58,63,68,73,78,83,88,93,98,103,108],{"name":48,"slug":34,"count":49,"latest_published_at":18},"AI",5028,{"name":51,"slug":52,"count":53,"latest_published_at":18},"Security","security",780,{"name":55,"slug":56,"count":57,"latest_published_at":18},"Policy","policy",417,{"name":59,"slug":60,"count":61,"latest_published_at":62},"Deals","deals",284,"2026-09-29T21:00:00.000Z",{"name":64,"slug":65,"count":66,"latest_published_at":67},"Hardware","hardware",194,"2026-09-29T13:16:04.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Science","science",154,"2026-09-28T13:19:18.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Consumer Tech","consumer-tech",142,"2026-09-29T18:38:03.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Dev Tools","dev-tools",89,"2026-09-29T17:15:00.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"Startups","startups",83,"2026-09-29T21:51:36.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"General","general",49,"2026-09-28T16:44:57.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":104,"slug":105,"count":106,"latest_published_at":107},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":109,"slug":110,"count":111,"latest_published_at":112},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
