On the Alternative Uses Task, their evolutionary persona-generation method increased response diversity by 78.8%, originality by 26.1%, flexibility by 49.5%, and overall creativity by 13.9% compared to task-only prompting, while keeping 98.5% of outputs valid. On a second benchmark, Infinity-Chat, the same method nearly doubled how far responses spread apart compared to assigning random personas. It also stacked with existing creativity-focused prompting techniques, adding another 18.6% diversity and 6.3% creativity on top.\n\nSingle-persona prompting - \"answer as a marketing expert\" - is already a common trick for getting more interesting output from a language model. This research suggests the trick is under-engineered: the shape of an entire set of personas, not the cleverness of any one persona, is what actually moves the needle. That matters for brainstorming tools, writing assistants, and multi-agent systems, where the goal is a spread of usable ideas rather than one polished answer.\n\nThe gains are measured on the team's own creativity benchmarks, so read \"nearly doubles diversity\" as an encouraging lab result, not a promise that your next AI brainstorm will stop sounding like it came from a committee.","[\"ai\",\"llm-research\",\"prompt-engineering\",\"creativity\"]","2026-09-28T04:00:00.000Z","2026-09-28T18:20:09.643Z","2026-09-28T18:20:16.323Z","published",null,[],"ai",[24,26,27,28],"llm-research","prompt-engineering","creativity",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.30492",0,{"sections":35},[36,39,43,48,53,58,62,67,72,77,82,87,91,96],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",4844,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",762,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",399,"2026-09-27T18:39:02.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",266,"2026-09-28T14:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",189,"2026-09-28T10:52:40.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",151,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",135,"2026-09-26T14:30:00.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":71},"Software","software",91,"2026-09-25T20:55:00.000Z",{"name":73,"slug":74,"count":75,"latest_published_at":76},"Dev Tools","dev-tools",84,"2026-09-26T04:20:58.000Z",{"name":78,"slug":79,"count":80,"latest_published_at":81},"Startups","startups",76,"2026-09-25T18:33:59.000Z",{"name":83,"slug":84,"count":85,"latest_published_at":86},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":88,"slug":89,"count":85,"latest_published_at":90},"General","general","2026-09-26T17:02:42.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",30,"2026-09-24T20:07:31.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
