countless lives could have been saved. Ignoring women in STEM/STEAM has consequences. Her contribution went well beyond topics like fresh air and ventilation. They included data collection—another area where WHO, CDC, and medical industry have been weak.

She walked away from slavery in 1826 carrying her baby. Then she went back — into a courtroom — and sued a white man to get her son. She won. She is one of the first Black women in America to do it. Sojourner Truth died on this day in 1883. New York was phasing out slavery. Her owner had promised her freedom early and then broke his word, so she walked out at dawn with her infant daughter and left the rest behind because she could not carry them. Then she found out that her five-year-old son Peter had been sold illegally into Alabama — which New York law forbade. She had no money and no education and could not read. She went to Quakers, raised the filing fee, and took the case to the Ulster County grand jury. It took months. She got him back. He came home with scars. She renamed herself in 1843 and spent the rest of her life on the road speaking — the only formerly enslaved woman most white Northern audiences had ever heard. In the 1860s she desegregated Washington's streetcars by simply refusing to get off, and had her shoulder dislocated by a conductor for it. She sued him too, and he lost his job. How many stories like Sojourner Truth’s were left out of what you were taught? If you want the stories beyond the textbook, this is where you start savvypurchase.samcart.com/pr…

Did you know? The largest maximum security prison in the United States sits on eighteen thousand acres of former plantation land in Louisiana. It is still a working farm. Men still pick crops in the fields by hand, watched by guards on horseback. And it is named after the country the people enslaved there were taken from. Angola. The land was four plantations. The one that gave the prison its name was called Angola because that was where its owner's workforce had come from. After the Civil War the property was leased for convict labour, and then the state bought it and kept the system going under a different name. Men still work the fields for cents an hour. Refusing to work has historically been punishable. It holds around five thousand people. The overwhelming majority are Black. Most are serving life without parole. It also hosts a rodeo, twice a year, open to the paying public, where prisoners compete for small prizes in front of an audience that drives in for the day. A plantation named for an African country, worked by Black men under armed guard, with a paying crowd on weekends. Nothing about that sentence is metaphor. Every word of it is the literal description of a functioning American institution.

这两天YouTube上有一个视频杀疯了, 成都女孩“墨韵”用咱们两千多年历史的古筝, 翻弹了老鹰乐队的摇滚神曲《加州旅馆》, 狂揽两千多万播放量,底下的老外在评论区直接听懵了。 《加州旅馆》最绝的就是那段吉他Solo, 而墨韵硬是用古筝清脆悠扬的拨弦声, 把这段西方摇滚的经典神仙还原了。 她用现场循环演奏的方式, 把摇滚的狂野律动和东方民乐的韵味完美融合。 很多外国网友惊呼,这绝对是他们听过最不可思议、最美妙的翻唱版本,硬生生让咱们这门历史悠久的传统乐器在全球狠狠圈了一波粉。 这段旋律对咱们在美国、尤其是德州生活的华人来说, 听着感受极其奇妙。德州本来就是一个极度热爱经典摇滚和吉他文化的地方,平时大家开着车在高速上,电台里最常放的公路神曲就是这首。但当这首刻进美国人骨子里的旋律,顺着咱们老祖宗的古筝弦流淌出来时,那种东方底蕴跟西方经典完美碰撞的感觉, 真的让人头皮发麻,又极其自豪。 我们的文化不仅能高山流水,玩起经典流行一样能惊艳世界。

李飞飞创办的 World Labs 被 AMD 收购,她本人出任 AMD 执行副总裁兼首席科学家。这篇文章是她写的公开信,讲了三件事: 1. 为什么创办 World Labs 2. 两年多 World Labs 做出了什么 3. 为什么选择 AMD 她为什么创办 World Labs 李飞飞从 2000 年读研开始做计算机视觉。她实验室做的 ImageNet,和神经网络算法、GPU 一起,被公认为开启了现代深度学习时代。之后她做过 Google Cloud AI 首席科学家,也是斯坦福 HAI 的创始院长。 生成式 AI 兴起后,前沿研究的重心从学术界转到了工业界,她判断创业是最能产生影响的路。2024 年初,她和 Ben Mildenhall(NeRF 的作者之一)、Justin Johnson 一起创办了 World Labs。 公司的核心信念是:光靠语言训练不出完整的智能。世界不是由文字组成的,是由真实的物体组成的。科学、娱乐、机器人这些领域的很多关键问题,都需要模型理解物理世界的结构和运行规律。这就是她一直说的“空间智能”。 两年多做出了什么 建了一支在图像、视频、三维重建方向很强的模型训练团队,还收购了 SceniX,目标是做机器人仿真。 最近发布了 Atlas,一个从零训练的全模态(omni)模型。它的思路很好懂:大语言模型根据前文预测下一个 token,Atlas 根据几张 2D 图像预测“下一个视角”该是什么样子。 她说 Atlas 把生成模型和多视角几何结合起来,基本解决了计算机视觉里的老难题“稀疏重建”,效果甚至超过了专用模型。 应用方向包括:给机器人强化学习搭建训练环境,为心理治疗和娱乐生成场景,以及房地产、设计、建筑行业的真实场景重建。 为什么是 AMD 她给的理由是,要把研究放大,就得离硬件更近。没有硬件,AI 的效率和规模都会受限,而且只能停留在数字世界里,这一点对机器人方向尤其重要。 AMD CEO 苏姿丰是 World Labs 的早期投资人,两家公司去年就开始深度合作,在 AMD GPU 上做模型训练和推理优化。 合作越深入,双方越觉得把软硬件、基础模型和应用整合在一起是顺理成章的事。 她还特意强调,加入 AMD 之后会继续开放地做研究,提供最好的开放模型和端到端平台。

Claude Code vs Codex vs Pi: which coding agent wins? @melissapan, PhD candidate at UC Berkeley’s Sky Computing Lab and previous @arena intern, explored the hidden “harness tax”: how the system surrounding an AI model affects its cost and performance. She reports three surprising findings. One: harness choice impacts cost more than accuracy.

从四川女孩到 82 亿美元创业并购 1976年,李飞飞出生于北京,在四川成都长大,就读于成都七中。 15岁左右,她随母亲移民美国,与已经先行赴美的父亲团聚。刚到新泽西时,一家人的生活并不宽裕。英语还不熟练的李飞飞,一边读高中,一边在中餐馆打工,后来还帮助家里经营干洗店。 真正改变她人生轨迹的,并不是斯坦福,而是普林斯顿。 1995年,李飞飞进入普林斯顿大学学习物理。大学期间,她平日在学校读书,周末却经常赶回新泽西,帮助父母打理干洗店。1999年,她以优异成绩从普林斯顿毕业,随后进入加州理工学院攻读博士。(Princeton University) 此后,她逐渐进入人工智能和计算机视觉研究领域。 她最重要的贡献之一,是推动创建了ImageNet——一个大规模图像数据库。后来深度学习在ImageNet上的突破,成为现代AI发展史上的重要转折点。 李飞飞随后成为斯坦福大学教授,并曾担任斯坦福人工智能实验室主任;2017—2018年间,她还曾担任Google Cloud AI/ML首席科学家。(斯坦фор德简介) 但她的故事并没有停在大学教授的位置上。 2024年,已经在AI学术界功成名就的李飞飞选择再次创业,与团队创办World Labs,把研究方向押在“空间智能”上——让AI不仅能够理解文字和二维图片,还能够理解、生成和模拟三维世界。 然后,故事迎来了一个惊人的转折。 2026年9月28日,AMD正式宣布与World Labs签署收购协议。 交易采用全股票方式,估值约82亿美元。 按照协议,交易完成后,李飞飞将加入AMD,担任执行副总裁兼首席科学家,直接向AMD董事长兼CEO苏姿丰汇报。 从成都七中的学生,到初到美国时在中餐馆打工; 从周末帮父母经营干洗店的普林斯顿学生,到斯坦福AI教授; 从创建ImageNet,到创办World Labs; 再到今天,一手创建的AI公司以约82亿美元的价格被AMD收购。 李飞飞用了三十多年,完成了一条很难被复制的人生轨迹。 这个故事最值得讲的,也许并不是“82亿美元”。 而是一个十几岁才来到美国、英语需要重新学习、家庭经济并不宽裕的移民女孩,最终走到了世界人工智能浪潮最前沿—— 她先让机器学会了“看见世界”,如今又试图让机器真正“理解世界”。

李飞飞戳破目前AI大模型最大幻觉和问题: 语言只是人类造出来的信号,宇宙是由真实物体、物理定律和三维空间构成的。 天空里没有写着字,大自然也不靠 token 运转。 今天的 LLM 能把话越说越像人,却仍然分不清距离、方位、体积,更预测不了杯子松手后会掉下去。 它们不是在理解世界,只是在统计文字。 没有空间智能,AI 永远只是黑暗中的文字匠。 能聊天,不等于能进入现实。 #李飞飞 #空间智能 #WorldModel #大模型局限性 #AGI #AI nitter.cf/nft_chen/status/210468…
🚨重磅!AMD 82亿美元全股拿下李飞飞 World Labs,李飞飞转任首席科学家! 具体细节如下:
🔹对价:约 $8.2B,全股票,预计 2026 年底交割 
🔹标的:空间智能实验室,能从文本/图/视频生成、重建、模拟可交互 3D 世界 
🔹人事:李飞飞任 AMD EVP 兼首席科学家,直接向苏姿丰汇报 
🔹意图:把前沿模型研究内化,加速推理、机器人、仿真与物理 AI 
🔹含义:AMD 从卖算力,走向“模型 + 硬件 + 系统”全栈卡位 世界模型进场,物理世界的 AI 战争升级。苏妈这步棋下得很大。 #AMD #李飞飞 #WorldLabs #空间智能 #物理AI #苏姿丰

One of the best things I ever did after I was raped was get super pissed off - it gave me the motivation to hound my attacker for 10y in criminal and civil court, do loads of victim advocacy, change policy in the city I was attacked in, get news coverage about it, and get a bad guy in charge at the DA's office removed from his position. As a counselor certified in anger management, I have to correct people on the myth that "anger is bad." It's not - it's the thing that loves you that mobilizes you to deal with a problem. The issue is whether it consumes you to illness or loss of control, or you choose to deal with it inappropriately. We need to stop wringing our hands over victims getting righteously angry simply because we have unworked issues with our own anger, or with women. It's not their problem to be tasked with navigating for us.
Women are repeatedly asked to convert rage into empathy before men are required to convert remorse into accountability.

卧槽😲 82亿美元,全股票,不套现,李飞飞把创办两年的公司卖给 AMD了,本人当首席科学家直接汇报苏姿丰,她9月1日刚发的 Atlas,27天后整个团队连人带技术一起被芯片厂收编了,太魔幻了, 整整两年时间,李飞飞没有跟着行业去扎堆做更会聊天的工具,而是硬生生在物理空间里凿出了一条路:真正的 AGI 绝不可能在文字接龙里诞生,走向三维世界,才算摸到了物理现实的真身。 业界都在震惊 AMD 砸了 82 亿美元全股票把 World Labs 收购,苏姿丰和李飞飞两位顶级女性在芯片与算法的巅峰会师。 文章里这句话我印象很深:世界不是由词组成的。 这句话几乎是在向过去三年所有沉迷于大语言模型的人,泼了一盆极度清醒的冷水。 无论现在的模型把文章写得多漂亮、把代码生成得多流畅,文本的本质,永远只是人类思维离散化后的投影。 真实的物理世界,物体怎么摆放、空间怎么连接、机械臂推倒一个杯子会产生什么摩擦力和重力反馈,这些东西在平面的文字里根本找不到答案。 机器要想真正走进工厂、医院和机器人,唯一的路,是学会感知、推理和构建三维世界。 她这两年做的事情,不是在屏幕里造一个更聪明的聊天框。 而是把三维世界里的新视角预测,做成了空间智能的下一个 Token:给几张照片,模型就能推演真实的物理空间,甚至用手机拍几秒视频,就能给机器人生成一个完整的现实孪生训练场。 这段自白之所以让我回味了很久,不是因为 82 亿美金有多夸张,而是它撕开了一个科技巨头争夺的真正终局: AMD 买下的从来不是一家初创公司,而是下一个十年芯片该为什么负载而存在的解释权。 如果空间模型不和底层的晶体管长在一起,空间计算就会又慢又贵,永远被锁在冷冰冰的数字代码里。 从当年用 ImageNet 亲手推开深度学习的大门,到今天跳出纯语言的幻象走向物理空间, 技术的自负总以为几行字就能穷尽宇宙,但唯有敬畏现实的泥土,才能推开下一扇门。

In 1996, a 26 year old artist named Maria Farmer walked into a federal building and told the FBI what she had seen and what had happened to her. She told them about Jeffrey Epstein, the abuse, and the young girls she had seen coming and going from his properties. She told them everything she could remember. According to Farmer, the FBI agent she spoke to eventually hung up on her. For nearly three decades, Maria Farmer lived with what it meant to tell the truth and have no one believe her. She had spoken up at enormous personal cost, only to be dismissed, ignored, and made to feel invisible. While the world moved on, while Epstein expanded his network and his crimes continued, Farmer carried what she knew largely on her own. Maria had grown up in Paducah, Kentucky, and had worked hard to build a life as a serious artist. In 1995, she earned a master's degree from the New York Academy of Art. She was talented, ambitious, and beginning to build the career she had worked for when Epstein entered her life through an introduction at her own graduate exhibition. What followed would change everything. She was hired to work for Epstein, first as an art advisor and later at the front desk of his New York mansion. While working there, she watched and saw things she could not simply forget. Then, in the summer of 1996, while living and working as an artist in residence at the Ohio estate of businessman Les Wexner, Farmer says she was sexually assaulted by Epstein and his associate Ghislaine Maxwell. She barricaded herself inside her room and called for help. When she finally managed to escape, she went directly to the FBI. They did not act. What Farmer did not know at the time was that her complaint, stamped September 3, 1996, would remain in a file for nearly three decades. It was not until December 2025, when the Department of Justice released a partial collection of Epstein documents, that the existence of the FBI record was finally confirmed. Her lawyer publicly confirmed that the complaint belonged to Maria. The records showed that allegations concerning Epstein's crimes had reached federal law enforcement nearly a decade before authorities in Palm Beach began their own investigation, the investigation that eventually led to his first prosecution. The FBI had the information. They had her name. They had her account of what happened. And they did nothing. In 2002, Farmer described her experiences to a journalist at *Vanity Fair*. The publication ultimately decided not to include her account, citing legal concerns. She tried again, and then again. Still, she was not heard. The years of silence took a toll that went far beyond the legal and political questions surrounding her case. They affected her body as well. In early 2019, shortly before she finally came forward publicly, Farmer was diagnosed with a rare brain tumor. A second form of cancer followed. She underwent surgeries and radiation while continuing to speak, paint, and fight for accountability. Farmer has said she believes the years of trauma and stress played a role in her illness. Whatever the cause, there is no question that she continued showing up for herself, for other survivors, and for the truth while carrying something most people would struggle to endure alone. And somewhere along the way, she returned to painting. She created satirical works depicting Epstein's associates, vivid and biting images that put names and faces to the network surrounding years of abuse. But she also began creating something quieter and much more personal. Farmer started painting pastel portraits of fellow survivors. Each woman is placed against a bright background of turquoise, pink, purple, yellow, blue, green, or orange. Farmer says each color represents the individual woman in the portrait. “I want these women to be honored individually,” she said. “I wanted it to portray how beautiful these women are and how strong they are.”
