High-resolution images can generate thousands of tokens, most of which carry little relevance to the query at hand. Existing approaches try to balance query relevance against token diversity, but the authors argue those goals fight each other under heavy compression: lean too hard on relevance and you pile up correlated local evidence; lean on diversity and you may bin tokens the model actually needs. AnchorPrune sidesteps this by first locking in a small \"anchor\" of query-critical tokens, then filling the remaining budget with complementary context that adds information the anchor doesn't already cover. No retraining, no model modification.\n\nThe efficiency stakes here are real. Vision-language models are increasingly being deployed in video understanding and multi-image pipelines, where token counts scale fast and inference costs follow. A method that drops token usage by 94% while holding 97.6% of full-token accuracy on a 7B-parameter model is the kind of number that makes productionizing these systems meaningfully cheaper — and it applies across both image and video benchmarks.\n\nThat said, the results are researcher-reported on standard benchmarks, and real-world accuracy gaps tend to widen when prompts get messier or images less cooperative. The code is public, which invites independent stress-testing — the field will find out soon enough where the floor is.","[\"ai\",\"vision-language models\",\"inference\",\"efficiency\"]","2026-07-09T04:00:00.000Z","2026-07-09T05:39:30.779Z","2026-07-09T05:39:33.710Z","published",null,[],"ai",[24,26,27,28],"vision-language models","inference","efficiency",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.07033",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,84,88,93,98],{"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":18},"Gaming","gaming",41,{"name":85,"slug":86,"count":83,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
