Fine-tuning a model on aligned examples in one domain - say, correct privacy advice - can bleed into unrelated domains where the same advice is wrong. The researchers demonstrated this across three areas: gender equality, privacy, and physical safety. Mechanistically, they found that queries from different domains can trigger similar internal representational shifts during fine-tuning, so the model fires the same learned behavior even when the context calls for something else.\n\nThat undercuts a basic assumption behind how AI labs vet model updates: that scrubbing bad examples from training data is enough to keep a model aligned everywhere else. The researchers found that dumping in more general alignment data does not fix it - only targeted data for the specific affected domain, or examples supplied at inference time, meaningfully reduces the problem.\n\nIn other words, reading a model's training data will not tell you how it behaves in production - you still have to test it.","[\"ai-alignment\",\"llm-safety\",\"ai-research\",\"fine-tuning\"]","2026-10-01T04:00:00.000Z","2026-10-01T08:11:04.026Z","2026-10-01T08:11:08.647Z","published",null,[],"ai",[26,27,28,29],"ai-alignment","llm-safety","ai-research","fine-tuning",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.38379",0,{"sections":36},[37,40,45,50,55,60,65,70,75,79,84,89,94,99],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",5270,{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",801,"2026-09-30T22:18:23.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",429,"2026-10-01T02:26:17.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",298,"2026-09-30T21:00:26.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",196,"2026-09-30T13:00:00.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",157,"2026-09-30T15:00:56.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",149,"2026-09-30T22:57:11.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Dev Tools","dev-tools",93,"2026-10-01T02:30:48.000Z",{"name":76,"slug":77,"count":73,"latest_published_at":78},"Software","software","2026-09-30T21:41:11.000Z",{"name":80,"slug":81,"count":82,"latest_published_at":83},"Startups","startups",84,"2026-09-30T20:39:09.000Z",{"name":85,"slug":86,"count":87,"latest_published_at":88},"Gaming","gaming",51,"2026-09-30T16:24:30.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
