It builds on flow-based activation steering (FLAS), training a shared controller on persona responses without ever pairing that training data with a specific requested strength, then calibrating the controller's output against measured trait expression afterward. Tested on Llama-3.1-8B, Qwen3-8B, and Gemma-3-4B, PersonaDose pushed trait expression 33.2, 18.3, and 17.8 points higher than contrastive activation addition, a common baseline steering technique, while holding coherence above a floor score of 75. On seven trained traits, requests calibrated to a specific target landed within 4.7 to 6.2 points of that target - but only for 14 to 22 of 28 possible target levels per model.\n\nThat accuracy gap is the real story. Activation steering already lets developers tune chatbot behavior without retraining a model, but 'strength 3 out of 5' has mostly meant guesswork - crank the coefficient and check the output. PersonaDose's calibration step tries to turn that guesswork into a number a product team can request and actually get.\n\nIt's one arXiv preprint testing three open models on lab-defined traits, and by the authors' own numbers, calibration missed its target on roughly a third of the settings tried - dial control you still have to double-check.","[\"ai\",\"activation-steering\",\"llm-research\",\"ai-safety\"]","2026-09-30T04:00:00.000Z","2026-09-30T05:44:11.183Z","2026-09-30T05:44:16.213Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Add explicit attribution — name the arXiv paper (arXiv:2609.36388, 'Persona Dosing: Calibrated Activation Steering for Graded Trait Control') and its posting date — since all figures and claims are currently presented without a cited source.","resolved","ai",[30,32,33,34],"activation-steering","llm-research","ai-safety",[36],{"name":37,"url":38},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.36388",0,{"sections":41},[42,45,49,53,58,63,68,73,78,83,88,93,98,103],{"name":43,"slug":30,"count":44,"latest_published_at":18},"AI",5028,{"name":46,"slug":47,"count":48,"latest_published_at":18},"Security","security",780,{"name":50,"slug":51,"count":52,"latest_published_at":18},"Policy","policy",417,{"name":54,"slug":55,"count":56,"latest_published_at":57},"Deals","deals",284,"2026-09-29T21:00:00.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":62},"Hardware","hardware",194,"2026-09-29T13:16:04.000Z",{"name":64,"slug":65,"count":66,"latest_published_at":67},"Science","science",154,"2026-09-28T13:19:18.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Consumer Tech","consumer-tech",142,"2026-09-29T18:38:03.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Dev Tools","dev-tools",89,"2026-09-29T17:15:00.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Startups","startups",83,"2026-09-29T21:51:36.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",49,"2026-09-28T16:44:57.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":104,"slug":105,"count":106,"latest_published_at":107},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
