Humanity's Sixth Sense Benchmark Reveals AI Visual Reasoning Shortcomings
Elorian and Scale AI have launched a new benchmark called Humanity's Sixth Sense (HSS) to evaluate AI models' intuitive visual reasoning capabilities. The benchmark consists of 522 questions based on 288 images and 234 short video clips, covering various reasoning categories. While human participants achieved a high aggregate pass rate of 93.1, the best AI model, GPT 6 Astra, scored only 53.6, indicating significant gaps in AI performance compared to human reasoning.

Anthropic报告：超八成代码由AI编写，人类工程师产出约为两年前的八倍
Anthropic在报告中说：截至今年五月，其八成以上代码已由AI编写；人类工程师当下的代码产出量，约为两年前的八倍。这意味着，机器已开始制造机器。 报告还发现，Claude的“研究判断”能力，比想象中更接近人类——而这一直被视为人类独有的能力。 由此引出当前AI的两个核心命题。 一、AI的自我改进 即人类利用AI将AI打造得更强。模型可以飞速编写底层训练脚本、生成海量数据，甚至自动修复代码缺陷。这就像一位铁匠用手中的锤子，打出一把更称手的新锤子，次日打铁的效率显著提升——但决定权还在人类铁匠手中。 二、AI的递归自我改进 想象一下，那把锤子开始自作主张，自行调控炉温、修改桌上的图纸，再开动机器锻造出一把“更擅长修改图纸”的锤子。下一把锤子诞生后立刻接管工坊，越改越快。当新一代模型接管、重投循环，改进者同时也成了被改进者。 二者的根本区别在于：演化的目标，究竟由谁设定？ 其中的鸿沟，在于一种被称为“研究品味”与“大局观”的抽象特质。 从底层机制看，递归改进缺一个即时且可信的裁判。代码飞轮之所以转得动，是因为有廉价而密集的“可验证奖励”——代码敲下，编译运行，对错当场分明。...

AI Just Had Its Most Insane Week of 2026 — And Most People Missed It
Something shifted this week. Not in a press-release way, not in a "here comes another AI product launch" way.

Four things happened between May 19 and May 23, 2026 that individually would each be worth a dedicated article.
