Of those, 10,555 multi-image instances were curated for reinforcement learning and checked by medical reviewers. The team trained a model called M3LLM using a three-stage process: standard fine-tuning, reinforcement learning that teaches the model which images actually answer the question asked, and a final broad fine-tuning pass. On the team's own benchmark, PMC-MI-Bench, M3LLM outperformed the strongest existing multimodal models on single-image, multi-image, and relative-position tasks, and it also posted new high scores on two independent public medical benchmarks, OmniMedVQA and MMMU-Med.\n\nMost medical AI tools are built and tested on one image at a time, but real diagnosis often means comparing a chest X-ray from six months ago against today's, or weighing several views of the same lesion. Mining multi-panel figures already published in medical journals is a cheap way around the usual bottleneck of scarce, privacy-restricted hospital imaging data, and it's a technique other labs could copy without needing clinical partnerships.\n\nThe approach was also tested on real longitudinal chest X-rays and a dermatology case set, which matters more than any benchmark score, though claiming state of the art on a benchmark you built yourself is worth reading with a raised eyebrow.","[\"ai\",\"medical-imaging\",\"multimodal-ai\",\"research\"]","2026-10-01T04:00:00.000Z","2026-10-02T05:49:47.389Z","2026-10-02T05:49:53.675Z","published",null,[],"ai",[24,26,27,28],"medical-imaging","multimodal-ai","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2511.22232",0,{"sections":35},[36,39,43,47,52,57,61,66,71,75,80,85,90,95],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",5671,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",820,{"name":44,"slug":45,"count":46,"latest_published_at":18},"Policy","policy",430,{"name":48,"slug":49,"count":50,"latest_published_at":51},"Deals","deals",298,"2026-09-30T21:00:26.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Hardware","hardware",196,"2026-09-30T13:00:00.000Z",{"name":58,"slug":59,"count":60,"latest_published_at":18},"Science","science",165,{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",149,"2026-09-30T22:57:11.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Dev Tools","dev-tools",93,"2026-10-01T02:30:48.000Z",{"name":72,"slug":73,"count":69,"latest_published_at":74},"Software","software","2026-09-30T21:41:11.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Startups","startups",84,"2026-09-30T20:39:09.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",51,"2026-09-30T16:24:30.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",50,"2026-09-30T21:37:54.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Reviews","reviews",31,"2026-09-28T14:31:34.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
