The system runs on twin-edge AI hosts behind a campus web gateway, pairing a FastAPI service with a local vector database and a local large language model served through Ollama, with plans to embed it in Moodle. The team ran two rounds of model bake-offs plus a separate test of how faithfully different setups stuck to the source evidence, then audited real conversations and quizzes. Several larger models were too slow for classroom use; a 12B model and a 7B model passed the speed gate, and a mixture-of-experts model fixed some errors while introducing new ones, so the team kept its existing 8B production model instead of swapping it in.\n\nThis is a case study in the unglamorous reality of deploying AI tools under real constraints. A campus can't ship a chatbot that takes ten seconds to answer a syllabus question, and it can't send student conversations to an outside vendor's cloud. The paper treats model size, evidence retrieval, and serving software as one combined decision rather than picking a flashy model and hoping the infrastructure catches up. That's a more honest framing than most splashy model announcements lately.\n\nThe researchers are careful to note what they haven't shown: whether students actually learn more, how the system holds up under a full class's peak traffic, or whether it's ready for a wider campus rollout. That's the kind of detail that's easy to skip when writing a press release.","[\"ai\",\"education\",\"rag\",\"llm-deployment\"]","2026-10-05T04:00:00.000Z","2026-10-05T11:28:38.373Z","2026-10-05T11:28:43.448Z","published",null,[],"ai",[24,26,27,28],"education","rag","llm-deployment",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.02510",0,{"sections":35},[36,39,43,48,53,58,62,67,71,75,80,85,90,95],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",6165,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",859,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",444,"2026-10-03T15:02:01.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",323,"2026-10-04T13:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",204,"2026-10-03T14:50:50.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",177,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",158,"2026-10-03T03:21:12.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":18},"Dev Tools","dev-tools",97,{"name":72,"slug":73,"count":70,"latest_published_at":74},"Software","software","2026-10-04T10:00:00.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Startups","startups",92,"2026-10-04T14:36:25.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",53,"2026-10-02T02:50:39.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"General","general",51,"2026-10-05T02:35:01.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"Reviews","reviews",32,"2026-10-02T18:00:00.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
