人工智能搜索代理不会在搜索方面失败，而是在查询变得模糊时无法提出正确的问题

AI search agents rarely fail at multi-step research because of the search itself. Their real problem is not asking the user for clarification when queries are ambiguous. A new benchmark called DiscoBench shows that models searching repeatedly instead of asking follow-up questions actually perform worse, at 51.9 percent, than those that just guess. Even the best model only hits 43 percent overall accuracy. When ambiguity is removed from the queries, accuracy jumps by up to 40 points. The article

LlamaIndex ‘legal-kb’：使用检索、查找、读取和 grep 工具对索引 v2 进行代理检索

LlamaIndex has published legal-kb , a public reference application on GitHub. It is described as a knowledge base for legal documents, powered by LlamaIndex Index v2 (the LlamaParse Platform). The project demonstrates a pattern the team calls a Retrieval Harness for agentic retrieval. The approach differs from single-shot retrieval. Instead of one embedding search per query, an agent is given filesystem-style tools. It can then crawl a large, evolving knowledge base to solve a task. The tools mi

AI 产品经理如何为 Agent 产品设计安全护栏？

Agent产品的安全护栏并非简单技术风控，而是产品设计的核心环节。本文深入剖析Agent安全性的本质挑战：从基础准确性提升到风险分层设计，从三层护栏构建到动态路由机制，揭示真正可靠的Agent产品如何通过精细化的边界设计，在能力与安全间取得平衡。 过去一年，很多团队做 Agent 产品时，最容易陷入一个误区：一上来就讨论“怎么拦截”“怎么审核”“怎么防越狱”。 但真正进入生产环境后你会发现，Agent 的安全问题不只是技术风控问题，而是一个完整的产品设计问题。 一个 Agent 会不会出事，不只取决于模型够不够强，也取决于产品经理有没有提前定义清楚：它能做什么、不能做什么、什么时候需要确认、什么时候必须交给人。 换句话说，Agent 的安全护栏，不是上线前临时加的一层“保险丝”，而应该是产品能力的一部分。 一、先别急着加护栏，先提高 Agent 的基础准确性 很多人理解的安全护栏，是在模型输出后做拦截。 比如发现敏感词就挡掉，发现格式不对就重试，发现回答危险就转人工。这当然有用，但它解决的是“结果已经偏了以后怎么补救”。 对 Agent 产品来说，更前置的问题是：为什么它会偏？ 如果

Qwen 的前任领导关于混合思维的错误之处以及他现在支持特工的原因

Junyang Lin was the technical lead of Alibaba’s Qwen project. He announced he was stepping down on March 3, 2026 . He now lists himself as an independent researcher on his personal site. In a talk titled ‘ Qwen: Towards a Generalist Model / Agent, ‘ he walks through the Qwen family. It ends on a single line: “Training models -> training agents.” He later expanded that line into an detailed post as an independent researcher. This article reads the talk and the detailed post together. What Lin’s T

Anthropic 推出 Claude Science Beta：用于可重复基因组学、蛋白质组学和化学信息学管道的多代理人工智能工作台

This week, Anthropic released Claude Science . It is an app for scientists, available in beta. It runs on Anthropic’s existing Claude models, not a new model. The app targets researchers who juggle databases, notebooks, and cluster terminals. It runs multi-step research and records how each result was made. The beta is available for Pro, Max, Team, and Enterprise plans. Claude Science builds on Anthropic’s life sciences work from last fall. That earlier work connected Claude to the scientific ec

NVIDIA HORIZON：一款免提代理，可改进 Git 工作树并达到 100% RTL 基准测试完成率

NVIDIA Research introduced HORIZON , a hands-free agent framework for hardware design. It treats hardware design as repository-level code evolution. This research team exercises the register-transfer level (RTL) instantiation. A structured Markdown harness becomes a project pack. A self-contained agent loop then evolves an isolated git worktree. It commits a version only when an executable acceptance gate passes. The research team reports 100% completion across every evaluated RTL benchmark suit
