Microsoft claims the Maia 200 gives 30% more performance per dollar than the first-gen Maia 100, an impressive feat considering the new chip also technically advertizes a 50% higher TDP than its predecessor.
大多数人认为芯片性能提升必然伴随着功耗增加和成本上升,但作者认为微软在Maia 200上实现了性能每美元提升30%的同时,功耗仅增加50%,这挑战了AI芯片领域'性能提升必然伴随能耗大幅增加'的行业共识,暗示了架构优化的巨大潜力。
The models are finally ready. Costs of inference are getting optimized with open models, and even on-device models.
大多数人认为AI领域仍然处于早期阶段,模型成本高且实用性有限,但作者认为模型已经'准备就绪',推理成本正在优化,这一观点暗示AI应用可能比大多数人预期的更快进入实用阶段,挑战了行业对AI成熟度的普遍认知。
We never stack model fees; you are charged a single rate based on the top tier model involved.
大多数人认为使用多个模型的多智能体系统会叠加各个模型的费用,导致成本高昂,但作者提出了创新的定价模式,只收取最顶级模型的单一费率。这种颠覆性的定价策略挑战了传统多模型服务的商业模式。
We now appear to be entering the era of token rationing.

The nuances of tuning the carburetors & the timing belts of these complex beasts are tasks better assigned to a few vendors to deliver maximum intelligence per dollar & amortize the costs across a broader population.
作者将AI系统比作复杂的机械,需要精细调整(化油器和正时皮带)。他建议将这种专业任务交给少数供应商,以实现每美元最大智能回报并分摊成本。这反映了AI应用开发的专业化和集中化趋势,对初创企业考虑是否自建AI能力有重要启示。
Models are tricky. Budgets prevent defaulting everyone to state-of-the-art. The legion of other models each have a personality.
作者详细描述了不同AI模型的特性差异,如Kimi K2.6创意性强但精确度较低,Qwen 3.6性能好但可能中断工作流,GLM 5.1擅长编程但速度较慢。这提醒开发者需要根据具体需求选择合适的模型,而非盲目追求最新或最大的模型,同时要注意预算限制。
His personal cost of capital made that possible.
大多数人认为马斯克的融资成功主要归因于他公司的创新技术和市场地位,但作者将其归结为'个人资本成本'这一概念。这挑战了传统商业融资理论,暗示创始人的个人品牌和声誉可能比公司基本面更重要,是一个反直觉的因果关系主张。
Pulled the trigger today & switched 100% of Lindy traffic to DeepSeek v4, churning from Anthropic models. Saves us millions of $ & we're actually seeing an _increase_ in performance on many core use cases.
Lindy完全切换到DeepSeek v4模型,节省数百万美元,同时核心用例性能还提升了。这个案例展示了从封闭模型转向开源模型的显著经济优势,但缺乏具体的节省金额和性能提升的具体数据点。

$84 vs $954 across the same 100 tasks, or ~11x cheaper.
成本对比数据显示Kimi 2.6模型比Opus模型便宜约11倍,完成相同100个任务的成本从954美元降至84美元。这一显著的成本差异(约870美元)是AI经济性的关键指标。11倍的成本优势表明开源模型在成本效益方面具有巨大潜力,可能加速AI技术的普及。
Even though per-token prices have fallen, the push for more AI adoption and increasingly autonomous agents have driven token consumption higher and higher.
大多数人认为AI成本下降会使AI应用更经济实惠,但作者认为尽管单位token价格下降,但AI使用量激增导致总成本反而上升。这与大多数人对AI成本下降的预期相悖,揭示了行业面临的成本悖论。
the total cost was under $20,000 and found several dozen more findings. While the specific run that found the bug above cost under $50, that number only makes sense with full hindsight. Like any search process, we can't know in advance which run will succeed.
2万美元找到「几十个」高严重性漏洞(包括一个27年历史的OpenBSD内核崩溃漏洞)——这个成本效益比彻底颠覆了传统安全审计的经济学。顶级渗透测试公司的日费率通常在数千到数万美元之间,且不保证结果。Mythos将漏洞发现的边际成本压缩到了每个漏洞数百美元级别,这意味着大规模、持续性的自动化漏洞狩猎在经济上已经完全可行。
At a time when many companies are blowing through their AI budgets, those token cost savings have become a major selling point for the company.
AI budget anxiety is becoming a real enterprise procurement signal — and Glean is one of the first companies to explicitly sell against it. This suggests the AI adoption cycle is entering a cost-optimization phase: the early 'try everything' enthusiasm is giving way to CFO scrutiny of LLM spend, which favors solutions that promise efficiency over raw capability.
CXL solves this by introducing a shared memory pool that expands capacity beyond GPU memory, enabling KV reuse across workers. With CXL's load/store semantics, KV data can be accessed with zero-copy, reducing recomputation, stabilizing latency, and significantly lowering cost per token.
Zero-copy access via CXL's load/store semantics is the key architectural advantage over existing solutions like CPU offloading or NVMe storage, which require serialization and DMA transfers. This makes CXL memory behave like extended GPU memory rather than a slower storage tier, preserving latency-sensitive inference performance.
Even the most valuable companies in the world cannot afford state-of-the-art intelligence for every conceivable use case.
大多数人认为顶级科技公司有无限资源可以采用最先进的AI技术,但作者认为即使是全球最有价值的企业也负担不起所有场景的最先进AI,因为成本效益比已经变得不可持续。这挑战了'大公司可以无限制采用新技术'的常识认知。
Uber capped employee AI spending after blowing through its budget in four months.
大多数人认为大型科技公司有充足的财务缓冲来支持AI采用,但作者认为即使是像Uber这样的大公司也难以承受AI成本,导致预算迅速耗尽。这挑战了'大公司有无限AI预算'的普遍认知,揭示了AI成本问题的普遍性。
Benchmarks are now measured on two different dimensions, the overall performance & the cost to achieve that intelligence.
大多数人认为AI评估主要关注性能指标,但作者认为评估标准已经转变为双重维度:性能和成本。这挑战了AI行业长期以来只关注性能的评估传统,暗示成本效率将成为与性能同等重要的评估标准。
Even the most valuable companies in the world cannot afford state-of-the-art intelligence for every conceivable use case.
大多数人认为顶级科技公司有无限资源可以采用最先进的AI技术,但作者认为即使是全球最有价值的企业也负担不起在最广泛场景中使用最先进AI,因为AI成本已经变得不可持续。这挑战了'大公司可以无限制采用新技术'的常规认知。

Running every query through Opus 4.7 is the fastest path to negative gross margins. The best Rest of Oz companies route across tiers of models — frontier models for the hardest tasks, mid-tier for the bulk, smaller custom or fine-tuned models where they've earned the right to use them.
大多数人认为使用最先进的大模型总是最佳选择,能提供最佳结果。但作者认为这是通往负毛利的最快路径。相反,'Oz的其他部分'公司会根据任务难度分层使用不同级别的模型,只为最困难的任务使用前沿模型,为批量任务使用中等模型,为特定工作使用小型定制或微调模型。这种成本优化策略使它们能够提供更具竞争力的价格。
In long sessions the bill typically lands at ~1/3 of comparable generic tooling.
这个数据点声称长期使用时成本通常相当于同类通用工具的1/3左右。这是一个相当大的成本节约声明,但文章没有提供与哪些具体工具进行比较,也没有说明比较的条件和度量标准。1/3的成本节约需要更详细的基准测试和对比数据来支持。
$0.07 /Mtok in · $0.014 /Mtok cached
这个价格数据点显示未缓存的令牌成本为每百万0.07美元,缓存的令牌成本为每百万0.014美元,即缓存后成本降低为原来的20%。这是一个具体的价格点,但没有说明这是官方定价还是基于特定使用场景的计算。与其他AI服务提供商相比,这个价格处于中等水平,但需要考虑实际使用中的额外成本。
of the roughly $30 billion year-over-year increase, around $20 billion came from HBM alone.
在300亿美元的同比增长中,约200亿美元来自HBM内存。这表明内存成本是推动总支出增长的主要因素,占比约67%,凸显了HBM在AI芯片成本结构中的主导地位。
Total spending on components across the top four designers more than doubled from 2024 to 2025, rising from $22 billion to $52 billion.
组件支出从2024年的220亿美元增长到2025年的520亿美元,增幅超过100%。这一显著增长反映了AI芯片供应链成本的急剧上升,以及行业对关键组件投入的大幅增加。
The Scientist AI is going to be trained using essentially the same machine learning techniques: stochastic gradient descent on large neural nets, transformers, whatever works best. It doesn't care about what is the architecture of the neural net. So all of the effort that is currently being done to improve, for example, memory and other properties and continual learning, can just be applied directly to the Scientist AI.
Bengio解释Scientist AI将使用与现有模型相同的基础技术,这意味着实现成本不会显著增加,打破了安全与能力必须取舍的常见假设,为安全AI提供了实用路径。
Imitation learning (Supervised Fine-Tuning) was ruled out because generating multi-turn labels is prohibitively expensive.
作者否定了模仿学习作为协调者训练方法的可行性,这与许多AI研究中偏好监督学习的常规做法相悖,提出了一个反直觉的观点。

这个案例展示了开放世界评估的实际应用,每年约5万美元的成本表明这种评估需要相当大的资源投入。相比传统基准测试,这种评估方式更接近真实应用场景,但也因此成本更高,难以大规模实施。
The benchmark tasks were meticulously constructed to be realistic, involving the hard work of hundreds of experts and likely millions of dollars — placing it among the most expensive economics papers of all time.
作者提到GDPval基准测试可能花费了数百万美元,由数百名专家参与构建。这一数据点显示了AI基准测试的高昂成本,但也暗示了这类测试可能存在资源分配不均的问题。考虑到其成本与实际经济影响之间的差距,这种高投入低产出的现象值得反思。
$200,000 per year in wasted standup meetings
【令人震惊的数字】每年 20 万美元浪费在无效的 Standup 会议上——这是对一个「中等规模工程团队」的估算。更深层的问题是:这笔钱不只是时间成本,而是「将工程师锁在低价值同步活动中」的机会成本。AI 编程时代,工程师最稀缺的资源是「深度思考时间」,而 Scrum 的会议文化恰好是这种时间的最大消耗者。
Across leading AI companies where breakdowns are available, the chips and computing time to run them account for 54% to 62% of total spending
AI硬件成本占AI公司总支出的一半以上(54%-62%),这凸显了计算资源在AI开发中的核心地位。如此高的比例表明,AI公司的竞争很大程度上转化为对计算资源的获取和利用能力的竞争。这也解释了为什么各大公司愿意为芯片支付高价并积极投资自研芯片。
When our engineers no longer spend time supervising Codex sessions, the economics of code changes completely. The perceived cost of each change drops because we're no longer investing human effort in driving the implementation itself.
大多数人认为AI编程会增加监督成本,但作者认为通过Symphony系统,人类监督成本实际上大幅下降,因为AI能够自主完成大部分实现工作。这个观点挑战了人们对AI编程成本结构的普遍认知,暗示正确的AI编排可能根本性地改变软件开发的经济模型。
IT budgets are getting blown out as some companies increasingly spend more on AI than on employees' salaries.
这个陈述提出了一个令人震惊的数据,即一些公司在人工智能上的支出超过了员工工资,需要核查这些公司的具体支出情况。

Because small, cheap, fast models are sufficient for much of the detection work, you don't need to judiciously deploy one expensive model and hope it looks in the right places. You can deploy cheap models broadly, scanning everything, and compensate for lower per-token intelligence with sheer coverage and lower cost-per-token.
这一观点提出了AI安全的经济新模式,通过广泛部署小型廉价模型来弥补单一大模型的不足。这种'广撒网'策略可能比依赖少数昂贵模型更有效,尤其在大规模代码库扫描场景中,为AI安全的经济可行性提供了新思路。
Eight out of eight models detected Mythos's flagship FreeBSD exploit, including one with only 3.6 billion active parameters costing $0.11 per million tokens.

令人惊讶的是:SELFDOUBT方法在处理剩余情况时,不仅显著优于基于采样的语义熵方法,而且计算成本降低了10倍。这一发现表明,通过分析模型推理过程中的自我怀疑和验证行为,可以在极低成本下实现比传统方法更准确的不确定性估计,为实际应用提供了高效解决方案。
using Claude 3.5 Sonnet for the experimentation phase typically costs around $15–$20 per run.
一篇通过 ICLR workshop 同行评审的科学论文,AI 生成成本约为 15-20 美元。相比之下,一位博士生培养成本超过 10 万美元,发表一篇顶会论文需要数月时间。这个成本差距意味着:如果这项技术成熟,科研论文的生产成本将下降数千倍。学术期刊、同行评审系统、学术出版业的整个商业模式,都将面临根本性的重构压力。
Cost (USD) to run the evaluation: GPT-5.4 (xhigh): $1,110, Claude Opus 4.6 (max): $1,055
运行一次 452 个任务的评测,GPT-5.4 花费 1110 美元,Claude Opus 4.6 花费 1055 美元——每个任务平均约 2.3 美元。而 Gemini 3 Flash 只需要 596 美元,实现了 27.7% 的成绩(vs 顶级模型的 33.3%)。这个性价比数据对 AI 选型决策极为关键:如果业务场景可以接受 27% 而非 33% 的成功率,Gemini 3 Flash 能节省近一半成本。在金融服务的大规模部署中,这个差异将被放大数千倍。
poorly organized code means agents need to read, "understand", and make changes to more files than necessary - polluting their context and costing you tokens.
【启发】技术债从「慢慢损害可维护性」变成了「立刻损害你的账单」。这是一个全新的技术债量化维度——不再只能用「未来的工时」来衡量,而可以用「每次 AI 调用的 token 超支」来实时计算。这为「说服管理层重视代码质量」提供了一个全新的、财务可量化的论据:烂代码不只是技术问题,它在每次 AI 执行任务时都在直接产生额外费用。
Humans abandon wikis because the maintenance burden grows faster than the value. LLMs don't get bored, don't forget to update a cross-reference, and can touch 15 files in one pass. The wiki stays maintained because the cost of maintenance is near zero.
【启发】这句话精准定位了 LLM 的「比较优势」所在:不是创造力,不是洞察力,而是「永不厌倦的维护」。人类知识库失败的根本原因是维护摩擦——而这恰好是 LLM 最擅长的。这对所有知识密集型组织的启发是:凡是人类会因「太繁琐而放弃」的知识维护任务,都是 LLM 的最佳应用场景。
the maintenance burden grows faster than the value.
知识管理系统的死亡往往不是因为缺乏信息,而是维护成本的指数级增长超过了信息本身的价值。LLM的引入将边际维护成本降至接近零,从根本上逆转了这一熵增趋势,使得知识库的长久存续和演化成为可能。
since reasoning models and agentic AI can rack up quite a bill
文章提醒了一个常被忽视的约束条件:AI的使用成本。在讨论AI替代人类时,人们往往默认AI是低成本方案,但推理模型和智能体的高昂算力成本意味着,仅凭能力覆盖并不等于经济上的可行替代,成本收益分析仍是决定性门槛。
would shareholders vote to spend 22% of an established company’s market cap to rescue a money-burning AI lab that has lost most of its differentiators?
这是一个深刻的反直觉推演。微软对OpenAI的重金投入变成了一种“沉没成本绑架”。如果收购,不仅要花费巨额市值拯救一个失去差异化的烧钱机器,还会摧毁微软自身的AI增长叙事;如果不救,则前期投资打水漂,云服务大客户流失。这种两难境地揭示了过度绑定高风险前沿技术的系统性反噬风险。
合計数百回、時には数千回に及ぶLLM呼び出しの中で、有望な仮説をさらに深掘りするのか、まったく新しい角度に広げるかを、Sakana Marlinはその都度判断しながら探索します。
数百到数千次 LLM 调用完成一次研究任务——这个规模令人震惊。一个用户提交一个研究主题,背后触发的是数千次 AI 推理调用,形成一棵庞大的假设探索树。从成本角度看,如果每次 LLM 调用均价 0.1 美元,1000 次调用就是 100 美元的计算成本。「数周人力工作」的价值与「100 美元计算成本」之间的鸿沟,正是 AI 替代知识工作的核心经济逻辑所在。
METR pays human programmers a minimum of $50 per hour, so getting a baseline for a single 160-hour task would cost at least $8,000.
一道测试题的人类基准成本高达 8000 美元——这个数字揭示了 AI 评测的一个被严重低估的物理限制:测量 AI 能力需要大量人类劳动,而随着 AI 能力向「月级任务」延伸,建立可靠基准的成本将呈超线性增长。更根本的问题是:你很难让一个有能力的程序员花数周时间做一个「测试任务」,即便报酬丰厚。人类评测员的可获得性,将成为 AI 能力评估的真正天花板。
Because Deep Extract is doing more work, it takes longer than a standard extraction call. That said, measured against the real alternative of someone manually reviewing a 500-page fund statement field by field, it's faster, cheaper, and consistent at scale.
大多数人认为更复杂的处理流程必然意味着更高的成本和更慢的速度。但作者提出Deep Extract虽然执行更多工作且比标准提取调用更耗时,但在大规模应用中仍然比人工审查更快、更便宜、更一致,这一观点挑战了人们对于复杂性与效率之间关系的传统理解。

This lovely old file cabinet is 52" high x 14-3/4" wide x 27-1/2" deep. Each drawer is 6-1/8" wide x 4-6/8" high x 18-1/4" deep. It has a few scratches on the side, but nothing that can't be touched up. Otherwise, it's in good condition. In the early 80's, I worked on a TV series called "Cassie & Co." starring Angie Dickinson. This (and another antique file cabinet) was purchased and used as set dressing in Angie/Cassie's office. When the show was canceled, I bought the cabinets and have had them ever since. I don't have specific background info on them.

“It’s harder to protect your reputation for reliability than to damage it. It turns out that, as usual, offence is cheaper than defence,” he says. “Everybody who cares about the preservation of any institution has to stop everything, ring the alarm bell, and start thinking about how to preserve that ‘membrane’ in a way that is morally permissible.”
Die wirtschaftlichen Schäden durch die globale Erhitzung sind sechsmal größer als bisher angenommen und vergleichbar mit denen eines andauernden Kriegs. Ein Prozent Temperaturanstieg verringert einem – noch nicht peer-reviewten – Arbeitspapier des amerikanischen National Bureau of Economic Research zufolge das weltweite Bruttosozialprodukt um 12%. Ein Temperaturanstieg bis 2100 um 3° wird Kapital und Verbrauch im Vergleich zu einer Welt ohne Erhitzung um 50% senken. Ohne die bisherige globale Erhitzung wäre die die weltweite Kaufkraft schon jetzt 37% höher. https://www.theguardian.com/environment/article/2024/may/17/economic-damage-climate-change-report

It is there-fore to be expected that the initial cost of the card system is nota fair criterion of its cost when in working order.
Setting up and learning a note taking or card index system has a reasonably large up-front cost, but learning it well and being able to rely on it over long periods of time will eventually reap larger and cheaper long-term outcomes and benefits.
Unless changing systems creates dramatically larger improvements, the cost of change will surely swamp the benefits making the switch useless. This advice given by Kaiser is still as true today as it was in 1908, we tend not to think about the efficiency as much now as he may have then however and fall trap to shiny object syndrome.

As card catalogs lost their functionality in libraries and were de-acquisitioned there was a wave of nostalgia which caused people to purchase them, often in auctions, at higher than expected prices. Once they had them, most of these purchasers realized that they didn't have functional uses in their homes for them (beyond wine or liquor bottle storage, small crafts, or use as a zettelkasten, which seem to be the only reasonable upcycling use cases I've seen and the last seems to be very rare and niche). They sit and take up space for very little value in return beyond some esthetic beauty and nostalgia. As a result many soured on their ownership. Most owners naturally want to recoup their original purchase price thinking that relative rarity will save them.
Combined with this there was a resurgence in mid-century design esthetic which had some furniture restorers and designers buying and doing full (and very pretty) expensive restorations of older 20s - 40s versions which sold at auctions for $4,500 and up. Given the rarity of some of these older, fine furniture versions along with the work in restoration and the limited market only those who had a tinge of nostalgia and money to burn made purchases which resulted in a limited number of actual sales.
These two factors mean that almost all of the listings for library card catalogs are heavily overvalued on eBay, Facebook Marketplace, Craig's List, Etsy, etc. The fine furniture restorations have set an artificially high price point which some feel theirs must match as well. The difference in quality however is stark. Because of their size and lack of functionality, there is a relative glut of them on the market which all bear inflated prices. Those who originally spent inordinate amounts for them, feel they will still have that same value to others, so they list them online for inflated prices.
I've been closely watching the online "market" for them for over a year and see the same several dozen or more listed across the country usually in the range of about $30-$60 per drawer. Many are listed as local pick up only, which further hampers the overall market. This also brings up the issue of shipping a 60 drawer card catalog which can easily run in the $800-$1,500+ range which usually requires additional shipping logistics involved with freight. Most catalogs are already overpriced, but adding an additional $1000 tax on top is a bridge too far for all but the highest end of the market. Some platforms like Etsy and eBay which take cuts of the final sale also add to the cost of the sale.
In the year and a half or more that I've been watching, I've only seen a handful of actual sales, all of which were local, and many of which were in the Los Angeles area. All of these sales have been for listings which eventually were reduced down to the $15 per drawer range. One local sale was in Wisconsin was for $10 per drawer (a 30 drawer file) and another in Los Angeles was for $12.50 per drawer (on a 20 drawer file).
Outside of a small handful of fine furniture listings in the $4,000+ range, most ex-Library card catalogs are generally very well worn and not in great condition which makes them less valuable as decoration pieces. In fact, many are often missing their original card catalog rods, have dents, dings, or other cosmetic issues. Some are missing drawers or have replacement drawers which don't match. Some may be slightly mismatched having been purchased in different eras as modular pieces and put together. Frequently they have been modified from their original states to include inserts or other material to fill in the holes which where almost standard in the bottoms of the drawers.
If you're in the market, know that it is tremendously inflated, a fact which most sellers are aware of as they've got them listed, some for many years, not resulting in actual sales. If you really want one and find it in a reasonable condition, I highly recommend making an offer for it at about $10 per drawer and potentially go up to $15. Anything higher than that is overpaying based on actual recent market conditions. If you have the money to burn, feel free, but keep in mind that like many others in the past, once the initial nostalgia has passed, you've probably got a large piece of relatively non-functional furniture in your home.
It's not common, but some government auction sites will list card catalogs for auction from time to time. Because they actively want to sell them these can be purchased in the $2-10 per drawer range or less. Often they tend toward the larger 60+ drawer range, aren't in good condition, or need to be picked up and shipped to your final destination, usually within a few days of purchase as the original owners don't or explicitly won't handle shipping. These are likely to need some restoration work to be decorative pieces in many homes.
If you want something brand new, you can check out Brodart, which is the only remaining card catalog manufacturer/sales firm I'm aware of in the United States. Their systems are modular, so you can pick and choose what you'd like to have. The only caveat is that they start at $1,700 for their smallest 9 drawer model and can go up to $11,648 (plus shipping) for a full 60 drawer model. The other potential drawback, for some, is that they are made of a mixture of wood, metal and plastic versus the all wood and metal fittings of older vintage models.
If you're in the market primarily for nostalgic reasons, then you might also consider looking at some of the older desktop wooden card catalogs which are often much less expensive, take up far less space, and can be wonderfully decorative. Some of the smaller two to six drawer desktop models have the benefit of potentially serving as recipe boxes or paper rolodexes, zettelkasten, or simply small office storage. Here again, the online markets are likely to be heavily overpriced with 2 drawer models being continually listed at $150 and 4 drawer models in the $250-400 range. These sellers know that these prices don't result in actual sales as they've been sitting on them for long periods of time (presumably hoping to get lucky). Here I'd recommend you make offers in the $20-30 per drawer range to see what you can find. Another benefit is that these smaller models are far cheaper to ship across the country. For additional advice on these, see: The Ultimate Guide to Zettelkasten Index Card Storage.
