Autonomous deep research agents (such as OpenAI Deep Research and Perplexity) represent a powerful leap toward automated knowledge synthesis. However, on open-ended and comprehensive inquiries, existing agents rely primarily on unconstrained search-and-generate loops. This leads to three systemic failures: redundant query loops, conflicting claims across sections, and runaway token expansion. Researchers from Tsinghua University and Renmin University of China unveil IOEDR (arXiv:2610.11566), a framework for Incremental Open-Ended Deep Research with a Structured Harness. IOEDR models the evolving research report as a dynamic hierarchical state graph coupled with a persistent, deduplicated evidence pool. Rather than executing open-ended browsing, the agent uses structured harness constraints to incrementally plan sections, identify specific evidential gaps, and trigger precision queries with dynamic termination conditions. On DeepResearch Bench, IOEDR achieves superior report coherence and verifiable fact density while reducing total token consumption by 33.2% and slashing search API requests by 61.4%.

Moonshot AI released a specialized Hybrid Code Search API powered by Kimi k1.5. Combining dense vector semantic embeddings with sparse AST inverted indexes, it resolves cross-file call hierarchies across 10-million-line monolithic codebases with search latency under 80ms.
