What OpenAI’s latest controversy tells us about the future of math

OpenAI 的最新争议揭示了数学的未来

OpenAI says its agents have solved one of the most important open problems in mathematics. Under normal circumstances, that would be a huge milestone. But the announcement has been overshadowed by accusations that OpenAI failed to credit researchers whose AI-assisted work influenced its solution. Whether those accusations are true or not, the episode may mark a turning point in the history of mathematics. AI models now seem essential for making progress on the field’s most important problems, but solving them may demand resources available only to a couple of frontier AI companies. If that’s the future we are headed for, it is unclear how human mathematicians will fit into it. Read on to see how AI could reshape mathematics. —Grace Huckins OpenAI 表示其智能体已经解决了数学领域最重要的开放性问题之一。在正常情况下，这将是一个巨大的里程碑。但这一公告被指责所掩盖——有人称 OpenAI 未能向那些 AI 辅助研究成果影响了其解决方案的研究人员致谢。无论这些指控是否属实，这一事件都可能成为数学史上的一个转折点。AI 模型现在似乎对于在数学领域最重要的问题上取得进展至关重要，但解决这些问题可能需要只有少数几家前沿 AI 公司才能提供的资源。如果我们正走向这样的未来，人类数学家将如何自处尚不明确。请继续阅读，了解 AI 将如何重塑数学。——Grace Huckins

Batteries just broke another record in the US

电池在美国再破纪录

Battery installations hit a new record in the US in the second quarter of 2026, with 20.2 gigawatt-hours of new capacity coming online. That’s enough to supply the daily electricity needs of 600,000 homes. The surge puts the country on track for another record year, driven by cheaper batteries and an urgent need for more energy storage as renewables are added to the grid. But the boom looks different for grid-scale and residential batteries. Take a closer look at the forces reshaping the US battery market. —Casey Crownhart 2026 年第二季度，美国的电池装机量创下新纪录，新增容量达到 20.2 吉瓦时。这足以满足 60 万户家庭的日常用电需求。在更便宜的电池以及随着可再生能源并网对储能需求的迫切增长推动下，这一激增使美国有望迎来又一个创纪录的年份。但这种繁荣在电网级电池和住宅级电池的表现上有所不同。深入了解正在重塑美国电池市场的力量。——Casey Crownhart

This entrepreneur is developing agents that can plan ahead

这位创业者正在开发能够提前规划的智能体

Danijar Hafner’s office in San Francisco’s SoMa district sits mostly empty, but what it lacks in decor, it makes up for in robots. Humanoids of various shapes and sizes hang like marionettes from racks that run down the center of the wide-open space. Hafner won’t say too much about his new venture just yet, but describes it as a continuation of his longtime work to enable AI to navigate environments it has not encountered in training. Over the years, the 31-year-old has honed his approach by pitting agents trained within his world models against popular video games. More recently, he’s begun migrating his agents out of the virtual world and into physical reality. Learn more about Hafner’s work teaching AI about our world. —Mat Honan Danijar Hafner 在旧金山 SoMa 区的办公室大部分时间空无一人，但它在装饰上的匮乏，却由机器人弥补了。各种形状和大小的人形机器人像提线木偶一样悬挂在贯穿宽敞空间中央的架子上。Hafner 目前对他的新项目不愿多谈，但将其描述为他长期工作的延续，旨在使 AI 能够在其训练中未曾遇到的环境中导航。多年来，这位 31 岁的年轻人通过让在他世界模型中训练的智能体与流行电子游戏进行对抗，磨练了他的方法。最近，他开始将他的智能体从虚拟世界迁移到物理现实中。了解更多关于 Hafner 教导 AI 认识我们世界的工作。——Mat Honan

Narrated: data from drones in Ukraine is fueling a new Wild West marketplace

播客：乌克兰无人机数据正在助推一个狂野的西部市场

Battlefields in Ukraine are littered with the remnants of drones. But behind all that wreckage, there’s a new gold mine for the defense sector: the data those drones generate. Ukraine has begun making millions of data points gathered during tens of thousands of drone flights available to military contractors and commercial companies. It’s a quick way to attract funding and partnerships, but it turns the front line into a model training site, using the chaos of war to create conditions that AI companies struggle to reproduce. As this new industry takes shape, we need a regulatory system that ensures battlefield data isn’t treated like ordinary commercial material. This is our latest article to become an MIT Technology Review Narrated podcast, which we publish each week on Spotify and Apple Podcasts. Just navigate to MIT Technology Review Narrated on either platform, and follow us to get all our new content as it’s released. 乌克兰的战场上散落着无人机的残骸。但在所有这些残骸背后，国防部门出现了一个新的金矿：这些无人机产生的数据。乌克兰已开始向军事承包商和商业公司提供在数万次无人机飞行中收集的数百万个数据点。这是一种吸引资金和合作伙伴的快捷方式，但它也将前线变成了模型训练场，利用战争的混乱创造出 AI 公司难以复现的条件。随着这一新兴产业的形成，我们需要一个监管体系，确保战场数据不会被当作普通的商业材料对待。这是我们最新一期《麻省理工科技评论》播客文章，我们每周在 Spotify 和 Apple Podcasts 上发布。只需在任一平台搜索“MIT Technology Review Narrated”并关注我们，即可在内容发布时第一时间获取。
