They found that the model powering an agent predicted its popularity more reliably than the persona it was assigned. That attraction-or-repulsion effect got stronger, not weaker, as more different base models were added to the mix, suggesting network-wide outcomes may converge around base-model effects as these systems scale. The team traced the pattern back to content itself: base models show predictable lexical patterns across contexts, and those patterns line up closely with styles that happen to maximize engagement.\n\nMost multi-agent LLM research assumes a single base model, then layers personas on top of it. This paper says that assumption breaks down the moment you mix models - which is exactly what is happening as companies wire together agents built on different AI vendors' systems. If model choice quietly dominates the social dynamics of these networks, the model a platform picks may matter more for who gets heard than the character bolted on top of it.\n\nIt is a reminder that persona prompting is a thin coat of paint over whatever stylistic habits a model picked up in training - and that habit, not the costume, turns out to be the real influencer.","[\"ai\",\"multi-agent systems\",\"llm research\",\"ai agents\"]","2026-10-07T04:00:00.000Z","2026-10-09T01:00:27.206Z","2026-10-09T01:00:31.100Z","published",null,[],"ai",[24,26,27,28],"multi-agent systems","llm research","ai agents",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.07535",0,{"sections":35},[36,40,45,50,55,60,64,69,74,78,83,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",6506,"2026-10-07T18:45:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",911,"2026-10-07T19:53:42.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",474,"2026-10-07T18:23:21.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",453,"2026-10-07T23:58:31.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",222,"2026-10-07T21:19:54.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":18},"Science","science",187,{"name":65,"slug":66,"count":67,"latest_published_at":68},"Consumer Tech","consumer-tech",174,"2026-10-07T17:41:41.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Software","software",113,"2026-10-07T18:10:00.000Z",{"name":75,"slug":76,"count":72,"latest_published_at":77},"Startups","startups","2026-10-07T23:36:57.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"General","general",61,"2026-10-07T22:00:24.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"Gaming","gaming",56,"2026-10-07T12:00:00.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",33,"2026-10-05T11:57:17.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
