That works fine for simple lookups but falls apart on corporate filings, where answering a single question might require pulling a revenue figure from a table, cross-referencing a footnote, and doing multi-step arithmetic. FinAgent-RAG addresses this with three components: a retriever trained on hard negatives to tell apart passages that look similar but contain different numbers; a reasoning module that writes and runs Python code for arithmetic instead of asking the model to do mental math; and a routing layer that assigns cheaper compute paths to simpler questions. On the FinQA, ConvFinQA, and TAT-QA benchmarks, the framework scores 76.81%, 78.46%, and 74.96% execution accuracy — beating the next-best baseline by between 5.6 and 9.3 percentage points while cutting API costs by 41.3% on FinQA.\n\nThe cost reduction is the detail most likely to matter in production. Financial institutions do not run a handful of queries; they run thousands, and a 41% API cost cut on a high-volume workload is a real budget line, not a footnote. The code-execution approach to arithmetic is also a quiet rebuke to the trend of trusting large language models to multiply numbers in their heads — something they remain unreliable at.\n\nThe system was tested across four different underlying LLMs, which suggests the gains are architectural rather than a lucky pairing with one model — though real-world performance on proprietary filings, with their idiosyncratic formatting, will tell a more complete story than any benchmark.","[\"ai\",\"retrieval-augmented generation\",\"finance\",\"research\"]","2026-07-07T04:00:00.000Z","2026-07-07T16:28:10.047Z","2026-07-07T16:28:12.956Z","published",null,[],"ai",[24,26,27,28],"retrieval-augmented generation","finance","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2605.05409",0,{"sections":35},[36,40,45,50,55,60,65,70,75,79,84,88,93,98],{"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":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"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"]
