The distinction matters because modern LLMs decode stochastically: ask the same question twice and you can get two different answers, so judging confidence against one response doesn't reflect what the model actually knows. The authors formally separate capability calibration from the standard response calibration and show the two diverge both in theory and in experiments. They also test existing confidence-estimation methods to see how well they hold up once capability calibration, rather than response calibration, is the actual target.\n\nThis isn't an academic nitpick. Capability calibration maps directly onto decisions AI companies already make, like predicting pass@k - the odds a model solves a problem given several attempts - and deciding how much inference budget to spend on a hard query. Most calibration numbers that get cited in papers and marketing are response-level, which means they may say less than advertised about a model's real reliability on a given task.\n\nConfidence scores already get treated as a selling point in model cards. This paper is a quiet argument that most of them are measuring the wrong thing.","[\"llm-calibration\",\"ai-research\",\"model-evaluation\",\"arxiv\"]","2026-09-30T04:00:00.000Z","2026-10-01T05:39:05.905Z","2026-10-01T05:39:10.605Z","published",null,[],"ai",[26,27,28,29],"llm-calibration","ai-research","model-evaluation","arxiv",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2602.13540",0,{"sections":36},[37,41,46,51,56,61,66,71,76,80,85,90,95,100],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",5269,"2026-10-01T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",801,"2026-09-30T22:18:23.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Policy","policy",429,"2026-10-01T02:26:17.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",298,"2026-09-30T21:00:26.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",196,"2026-09-30T13:00:00.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Science","science",157,"2026-09-30T15:00:56.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",149,"2026-09-30T22:57:11.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Dev Tools","dev-tools",93,"2026-10-01T02:30:48.000Z",{"name":77,"slug":78,"count":74,"latest_published_at":79},"Software","software","2026-09-30T21:41:11.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",84,"2026-09-30T20:39:09.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",51,"2026-09-30T16:24:30.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
