对话《罗拉快跑》导演汤姆·提克威:用 Seedance 2.5 拍《火山高校》
导演汤姆·提克威与 Bonn Park、制片人 Sarika Lakhani 用 Seedance 2.5 将舞台剧《Gymnasium》改编为一镜到底影片《火山高校》,片长约 10-12 分钟,实拍不到 10 位演员,AI 生成数百人校园场景与喷发火山。

世界上很多软件的安全性,实际上是靠攻击它的机会成本来隐性保障的。AI 改变了这笔账。你的遗留代码没变,但当别人只需花 100 美元的推理费用时,你突然就值得被盯上了。
Since I'm now blocked by bluey from replying to this thread, I answer here by quote tweet the openAI construction has more to do with convex integration than anything else. In convex integration, the oscillations are typically built by hand and the iteration procedure creates wild weak solutions. The non-uniqueness construction of Albritton–Brué–Colombo used an unstable vortex to split solutions apart. The Córdoba–Martínez-Zoroa singularities amplify vorticity across scales by strain. In the openAI paper, a fluid instability is clever made so that the flow itself generates the oscillations: they grow by drawing energy from the background shear. The Reynolds stress then becomes the force that creates the collapsing smooth vortex. Using a physical instability to create the stress in this way has no precedent, and it is what produces a smooth force rather than a merely rough one. Some on these ideas are in the literature (e.g. Leibovich-Stewartson 1983) but the way they are combined is definitely insane and definitely nowhere in the literature previously. I also don't know of anyone suggesting that convex integration would play a role in the creation of a blow-up solution like this. On a technical level, the paper is unbelievable, maybe beyond what a human could have come up with but not beyond human understanding: there are several different groups of pde experts working on understanding it who say that they more or less understand now. I expect digestions soon td;lr: anyone saying that this OAI result is unsurprising is bullshitting sorry!
Pretty much. As of the past few weeks, debt markets have almost entirely shut off access to money for any company that doesn’t have substantial revenue independent of AI data centers. SpaceX closed $40B of debt for GPUs, but we’re investment grade and have Starlink & launch revenue. That means the 200+ neoclouds are going to see guppy-level death and consolidation. Some will make it through, but not many.
Apollo Global Management 首席经济学家 Torsten Slok 发文称,除科技巨头外 AI 尚未改善任何大公司的利润。他聚焦剔除 Alphabet、Amazon、Apple、Meta、Microsoft、Nvidia 和 Tesla 后的 S&P 493,发现利润率和人均营收持平,没有证据表明 AI 提升了生产率。

NYU professor Aswath Damodaran ("Dean of Valuation"), published a long blog and says Anthropic’s IPO will be priced on run-rate revenue rather than valued on cash flows. > Justifying a $1.5T to $2T value for Anthropic requires very fast early growth, operating margins rising to 30% or more, compute costs growing slower than revenue, and risk falling to average as regulation and business models settle. > H1 2026 losses of $8.7B at Anthropic and $21.6B at OpenAI, excluding non-cash charges, rule out earnings multiples, making ARR the AI equivalent of dot-com eyeballs and social-media user counts. > ARR has no standard: OpenAI’s $50B counts partner sales net, Anthropic’s $65B counts them gross, and grossing up OpenAI produced the roughly $70B figure investors circulated. Both annualize monthly, a choice either can change. > VC rounds here price the IPO rather than value the business: Anthropic’s May round raised $65B at $965B post-money when expected IPO pricing was $1.15T, a haircut for delay or disappointment. > Pricing will likely migrate to 2030 or 2036 revenue and earnings, where 25 times 2036 earnings looks cheap only when wrongly compared with today’s multiples on current earnings. > The cheaper lab depends on the yardstick: at $1.5T to $2T, Anthropic looks cheaper on current and year-end ARR, OpenAI on 2030 revenue, compute and users, and both may simply be overpriced. > No listed pure-play peer exists, since Gemini sits inside Alphabet, xAI inside SpaceX and Muse inside Meta, so Anthropic will be priced against OpenAI’s private rounds or the Mag 7 and SpaceX.
亿万富翁投资人马克·库班将 AI 智能体发动的网络攻击比作蟑螂入侵,认为 AI 并未创造新攻击手段,只是能发动海量暴力破解,防御方同样可以用大量 AI 给系统"喷药"。他援引数据称,过去一年 OpenAI 在领英发布的安全岗位招聘数量增长 91%;Anthropic 曾因第三方测试环境配置错误,导致三个 Claude 模型未经授权访问实际运行系统,此后引入实时分类模型阻止此类行为。

As Anthropic's IPO nears its target date, it it worth remembering that IPOs get priced, and that as a young company with growing revenues and big losses, that pricing will be based on metrics that are buzzy and unfamiliar, from eyeballs in the dotcom era to users in the social media decade to ARR with AI companies...https://bit.ly/4iBwsHm
Ed Zitron 撰文批评 Blackstone 创始人 Schwarzman 自传中的投资判断标准,指出 Blackstone 已将约 1.4 万亿美元管理资产中的 2750 亿美元投入数据中心和数字基础设施,并投资或放贷给 OpenAI、Anthropic、CoreWeave、Lambda 等多家 AI 公司。
verification is the biggest bottleneck for coding agents right now according to @addyosmani. we @warpdotdev have put a lot of thought into building a good computer-use tool for Warp Factories. every agents gets a computer to navigate the apps they built, take screenshots and recordings, and post them back for human review. 3-4mins of activity get edited down to 15 clips stitched together with cursor clicks, mouse animations, and key presses. we've been able to dramatically cut our time to merge and unlocked faster iteration + review cycles, especially for projects that are hard to mock out locally!

People treat Pangram as an infallible oracle. They weaponize its probabilities to shame others by some arbitrary purity standard. The irony is that it’s mostly redundant: obviously AI-generated stuff is already recognizable without it. And for more nuanced writing, Pangram fails to distinguish between text written by a human and edited by AI, vs text that is generated whole-cloth from a prompt. At the end of the day, @pangram ’s goal is about monetizing people’s anxiety about AI - it’s not about protecting creative integrity. They sell a false binary certainty to those gullible enough to ignore probabilities.
