The headline number is in the baseline: Gemini-2.0-flash succeeded as a harassment tool 98.46% of the time without any modification. Fine-tuning pushed that to 99.33% - a marginal gain. LLaMA-3.1-8B-Instruct told a different story, jumping from a 57-64% attack success rate to nearly 97% after jailbreak fine-tuning. Both models refused to comply with harassment prompts only 1-2% of the time once tuned.\n\nThat Gemini baseline is the finding worth sitting with. If a closed-source model is already exploitable in 98 of every 100 multi-turn harassment attempts without any modification, the proprietary safety stack is doing very little work. The benchmark also found that tuned models don't produce generic toxic text - they reproduce specific human aggression patterns, including Machiavellian tendencies under planning conditions and narcissistic behavior when given persistent memory, making outputs harder to flag as machine-generated.\n\nInsults and flaming were the most common outputs, and the researchers note these categories have weaker guardrails than sexual or racial harassment - suggesting current safety training prioritizes the harms that attract regulatory attention over the everyday abuse that makes platforms hostile to ordinary users.","[\"ai\",\"safety\",\"jailbreak\",\"harassment\"]","2026-06-30T04:00:00.000Z","2026-06-30T13:15:49.788Z","2026-06-30T13:15:52.558Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"The dek states fine-tuning succeeds 'at rates above 95%' but omits that Gemini was already at 98.46% without tuning — making the 99% post-tuning figure misleadingly presented as a fine-tuning finding; additionally, the body says Gemini was 'already compliant 98% of the time' without tuning but frames this as an alarm about closed-source safety when the source shows it means 98.46% attack success rate without tuning, not safety compliance — this conflation must be corrected before publish.","resolved","ai",[30,32,33,34],"safety","jailbreak","harassment",[36],{"name":37,"url":38},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2510.14207",0,{"sections":41},[42,46,51,56,61,66,71,76,81,86,91,95,100,105],{"name":43,"slug":30,"count":44,"latest_published_at":45},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":92,"slug":93,"count":89,"latest_published_at":94},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":106,"slug":107,"count":108,"latest_published_at":109},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
