The system computes what the authors call a Metacognitive State Vector, scoring each query across five dimensions borrowed from cognitive psychology: emotional response, correctness evaluation, experiential match, conflicting information, and problem importance. Based on those scores, the framework automatically routes simple queries through fast System 1 processing and harder ones through slower, deliberative System 2 processing that recruits multiple model nodes. In System 2 mode, graph-theoretic algorithms assign each node a role - domain expert, critic, evaluator, synthesizer, or generalist - based on its own metacognitive state, and the demo visualizes the whole process with real-time radar charts.\n\nLLMs are bad at knowing what they don't know, which is a big reason they hallucinate confidently instead of flagging doubt. This framework is a rare attempt to bolt an actual self-monitoring layer onto an ensemble, rather than just prompting a model to 'rate your confidence' and hoping the number means something. If self-awareness signals can reliably trigger slower, more scrutinized reasoning, that's a plausible path toward LLM systems that know when to ask for help.\n\nFor now it's a demo built on illustrative examples, not a benchmark run against hallucination-heavy tasks - the harder test is whether the same routing holds up once the queries stop being hand-picked.","[\"ai\",\"llms\",\"multi-agent systems\",\"metacognition\"]","2026-08-18T04:00:00.000Z","2026-08-18T09:00:28.764Z","2026-08-18T09:00:40.555Z","published",null,[],"ai",[24,26,27,28],"llms","multi-agent systems","metacognition",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.15400",0,{"sections":35},[36,40,44,49,54,59,64,69,74,78,83,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":39},"Security","security",435,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":18},"Dev Tools","dev-tools",69,{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
