The authors examine existing methods across pre-training, fine-tuning, and deployment, and summarize defense mechanisms proposed so far. It's a survey, not a new technique - the contribution is organizing a fragmented body of research, not shipping a model or benchmark result.\n\nFederated learning has struggled to find a home with LLMs because full-model updates are expensive to move between devices and a central server. Tuning only prompts, rather than full model weights, is one way researchers have tried to make that exchange cheaper - though the survey itself doesn't quantify how much cheaper, or specify what kinds of clients are involved. That's the gap this paper says still needs closing: the trade-offs are catalogued, not resolved.\n\nSurveys like this tend to arrive when a subfield has accumulated enough disconnected papers to need a map. Whether federated prompt learning becomes a standard tool or a footnote depends on work this paper doesn't do - actually benchmarking it against centralized fine-tuning at scale.","[\"federated learning\",\"large language models\",\"prompt tuning\",\"privacy\"]","2026-08-17T04:00:00.000Z","2026-08-17T07:48:38.661Z","2026-08-17T07:48:50.467Z","published",null,[24],{"id":25,"reviewer":26,"round":27,"reason":28,"status":29},"editor-r1","editor",1,"Cut or clearly flag as inference the specific claims not in the source material — 'clients are phones, hospitals, or other resource-constrained systems' and 'prompt-based approaches are lighter-weight than shipping full model updates' are asserted as fact but appear nowhere in the survey abstract; only report what the paper itself states.","resolved","ai",[32,33,34,35],"federated learning","large language models","prompt tuning","privacy",[37],{"name":38,"url":39},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.13844",0,{"sections":42},[43,47,51,56,61,66,71,76,81,86,91,96,101,106],{"name":44,"slug":30,"count":45,"latest_published_at":46},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":46},"Security","security",435,{"name":52,"slug":53,"count":54,"latest_published_at":55},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Dev Tools","dev-tools",69,"2026-08-18T04:00:00.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":107,"slug":108,"count":109,"latest_published_at":110},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
