Rather than trimming the input or fine-tuning the model, ReContext uses the model's own internal attention signals to identify relevant passages, assembles them into an evidence pool, and replays that pool just before the model generates its final answer — all while keeping the original full context intact. The recursive selection loop separates the job of finding evidence from the job of answering, without touching weights or adding external memory stores. Tests across eight long-context benchmarks at 128K context length showed consistent gains on Qwen3-4B, Qwen3-8B, and Llama3-8B.\n\nThe practical implication is real: companies already paying for large context windows are not necessarily getting their money's worth, because longer inputs increase the odds that a model's attention diffuses and critical evidence gets underweighted. A plug-in inference wrapper that reliably improves utilization — without retraining — is a cheaper fix than either model-level fine-tuning or retrieval-augmented pipelines bolted on the outside. The method also has a theoretical framing in associative memory research, treating attention as a cue-trace association and replay as trace reactivation, which gives it more intellectual scaffolding than most prompt-engineering tricks.\n\nThe code is public on GitHub, so the real test will come from practitioners stress-testing it on messier, real-world documents rather than the curated benchmarks where inference papers tend to shine.","[\"ai\",\"large-language-models\",\"long-context\",\"inference\"]","2026-07-03T04:00:00.000Z","2026-07-03T06:17:31.924Z","2026-07-03T06:17:35.233Z","published",null,[],"ai",[24,26,27,28],"large-language-models","long-context","inference",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.02509",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
