Google AI 团队分享如何为 LLM-as-a-Judge 评测编写可靠的评分标准

Google AI 团队发布教程，讲解如何为 LLM-as-a-Judge 评测编写可靠的布尔式评分标准，指出模糊提示会导致评估不一致和浪费 token。文中给出四条经验：问题保持原子化且互不重叠、只让评判模型评估客观事实（可用 RFC 2119 术语如 MUST 表述）、只评 prompt 中明确要求的内容、用专家标注的 golden set 校准评判模型直至与人类评分一致。

赵昊与百度百舸团队对谈：世界模型如何走向规模化训练

百度智能云具身智能前沿讲堂上，清华大学AIR助理教授赵昊与百度智能云AI计算首席科学家王雁鹏等对谈世界模型规模化问题。赵昊提出以3D/4D Token为核心的世界模型路线，认为世界模型不等于视频生成，需表达空间结构、光学属性和速度、加速度等动态信息；其OmniNWM通过动作编码与相机参数解耦，实现200帧稳定生成，并与精锋医疗、极智嘉分别合作手术预演和仓库机器人场景。

Elvis Saravia：AI 工程师应从零构建最小 harness 掌握上下文工程

Elvis Saravia 提出 harness 并非千篇一律，好的 harness 应解决上下文工程问题，关键在于理解并优化系统提示词、缓存和有效工具调用等底层细节。他建议用自己喜欢的语言构建一个带基本 agent 循环、系统提示词和工具调用能力的最小 harness，在用例上测试验证并迭代，掌握这些可调旋钮后再迁移到生产级 harness。

Ethan Mollick 推荐 AI 时代之前的三页复杂系统失效论述，并提出用 AI 构建系统防御新哲学

Ethan Mollick 分享 Richard I. Cook 写于 AI 出现之前的《How Complex Systems Fail》三页内容，称其值得阅读。核心观点是复杂系统带病运行但仍存活，因为缺陷很少同时对齐，给了人类介入的机会；而 AI 能发现或制造对齐的缺陷，因此需要一套借助 AI 的系统防御新哲学。
