Hybrid Deep Searcher: Scalable Parallel and Sequential Search Reasoning 事件

Hybrid Deep Searcher: Scalable Parallel and Sequential Search Reasoning arXiv:2508.19113v3 Announce Type: replace Abstract: Large reasoning models (LRMs) combined with retrieval-augmented generation (RAG) have enabled deep research agents capable of multi-step reasoning with external knowledge retrieval. However, we find that existing approaches rarely demonstrate test-time search scaling. Methods that extend reasoning through single-query sequential search suffer from limited evidence coverage
