arXiv:2608. 06305v1 Announce Type: new Abstract: Retrieval-augmented generation over long documents is dominated by one design: chunk the text, embed the chunks, and surface the top-k nearest neighbours of the query.

KnowForge is a modular pipeline for open‑domain multimodal document question answering that separates retrieval, judging, and reading into distinct agents. It uses a hybrid‑retrieval knowledge‑point index, a Locator agent for searching, a Bridge Judge to enforce a second hop, a Deep Reader that handles text, images, and tables, and a synthesizer with format checking. On the M3DocVQA benchmark it achieves an F1 of 47.5, outperforming prior systems by 11 points, and shows strong gains on MultiHop‑RAG and MMLongBench‑Doc as well.

CompLit is a new literature search benchmark covering all eight arXiv domains, designed to evaluate agents on three diagnostic settings: implicit, cumulative, and unmet needs. The benchmark shows that top agents like Codex and Claude Code perform well on standard queries (86‑87%) but drop to 66‑68% on implicit queries, lose additional accuracy when requirements accumulate, and abstain on up to 53% of unmet queries. The study finds that agents often locate the correct or near‑correct paper but misjudge it, indicating a need for more reliable search capabilities.
