Instead of simply nudging a model's outputs until it complies, the researchers first identified what they call \"acceptance subspaces\" - clusters of internal feature vectors that sit outside a model's refusal circuitry. They then used gradient optimization to steer prompt embeddings from the refusal zone into the acceptance zone. The result: attack success rates of 80-95% against Gemma2, Llama3.2, and Qwen2.5, often within seconds. Existing methods, by comparison, frequently fail outright or require hours of compute.\n\nThe speed gap is what makes this notable. Safety red-teaming has historically been slow and expensive enough that labs could afford to treat it as a periodic audit. A technique that cuts attack time from hours to seconds changes that calculus - it lowers the bar for anyone probing a deployed model, and it raises the pressure on defenders to match that pace. Mechanistic interpretability, a field mostly valued for explaining model behavior, now has a direct offensive application.\n\nThe same map that reveals where refusals live can, in principle, guide the construction of targeted defenses - but only if safety teams move faster than the researchers publishing attack code. The code and datasets are public on GitHub.","[\"ai\",\"security\",\"llm\",\"interpretability\"]","2026-07-07T04:00:00.000Z","2026-07-07T17:16:19.216Z","2026-07-07T17:16:22.298Z","published",null,[],"security",[26,24,27,28],"ai","llm","interpretability",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2503.06269",0,{"sections":35},[36,40,44,49,54,59,64,69,74,78,83,87,92,97],{"name":37,"slug":26,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":24,"count":42,"latest_published_at":43},"Security",294,"2026-07-15T19:59:48.000Z",{"name":45,"slug":46,"count":47,"latest_published_at":48},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":79,"slug":80,"count":81,"latest_published_at":82},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":84,"slug":85,"count":81,"latest_published_at":86},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":88,"slug":89,"count":90,"latest_published_at":91},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":93,"slug":94,"count":95,"latest_published_at":96},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":98,"slug":99,"count":100,"latest_published_at":101},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
