Give it a parameter name, a physical description, and some domain context, and a multi-agent pipeline searches the literature, extracts and weights reported values by relevance, and fits a probability distribution using AIC model selection. If no literature turns up, it falls back to an uninformative prior rather than guessing. The team tested it on 24 parameters across 10 scientific domains, running three open-weight local models against a single-prompt LLM baseline.\n\nOn raw prior quality, Distribird only tied that baseline - not a great headline for a new tool. The real difference shows up when you ask it something it shouldn't answer. Distribird's validity layer declines out-of-scope requests, while the single-prompt baseline confidently invented priors anyway in 11 of 30 model-parameter cases. Every prior Distribird does produce is traced to specific papers and values, and because the models run locally, no parameter descriptions or unpublished modeling details leave the researcher's machine - only generated search terms hit public databases.\n\nThat's a modest pitch by AI-tool standards: not smarter, just more honest about what it doesn't know and where its numbers came from. For calibration work that ends up in peer-reviewed papers, that kind of paper trail may matter more than a few extra accuracy points.","[\"bayesian-modeling\",\"ai-agents\",\"scientific-research\",\"open-weight-models\"]","2026-08-19T04:00:00.000Z","2026-08-19T13:10:35.549Z","2026-08-19T13:10:47.369Z","published",null,[],"ai",[26,27,28,29],"bayesian-modeling","ai-agents","scientific-research","open-weight-models",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2608.11210",0,{"sections":36},[37,41,45,50,55,60,65,70,75,80,85,90,95,100],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":40},"Security","security",435,{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",69,"2026-08-18T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",33,"2026-08-18T22:18:13.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
