低波动压缩到四年第8百分位,历史上30天内确实容易出方向。但同样压缩,2018年末往下、2023年初往上,差在哪儿?当时有没有增量资金。现在ETF没爆量,链上稳定币余额也没见拐点——那就别急着喊突破,看戏等资金先动。 xitter.cf/Jamie1Coutts/status/20…
Bitcoin volatility has collapsed, with 90d realised volatility at the 8th percentile of its trailing four-year history. The 180d close range was at the 12th percentile, while DVOL is very low as well. Bitcoin has entered an extreme low-vol and transition state. These tend to resolve over the next 30-60days. What matters more is how the range ultimately resolves. The overwhelming majority of upside breaks have been sustained with strong forward median returns. Downside breaks have been mixed, with several violent reversals. Which way this resolves largely depends on the outlook for liquidity.
Grok 4.6缓存价从$0.3涨到$0.5——涨了67%。都在吹模型变强变便宜,真正的生意在token烧起来之后,不是发布那一刻。币圈AI叙事还在讲训练革命,厂商已经卷推理消耗了,这错位挺有喜剧效果的。热闹看看就好,别把PPT当基本面。 xitter.cf/ArtificialAnlys/status…
SpaceXAI's Grok 4.6 scores 61 on the Artificial Analysis Intelligence Index, joining the frontier in line with GPT-5.6 Sol, with standout agentic performance at lower cost
Grok 4.6 gains 5 points over Grok 4.5 on the Intelligence Index just over one month after its release, or +23 points compared to Grok 4.3. This brings SpaceXAI back to the intelligence frontier alongside OpenAI, behind only Anthropic.
Key takeaways:
➤ Grok 4.6 joins the frontier of the Artificial Analysis Intelligence Index: It scores 61, in line with GPT-5.6 Sol (max), behind Claude Opus 5 (max, 63) and Claude Fable 5 (max with fallback, 62), and just ahead of Kimi K3
➤ Strong agentic performance: Grok 4.6 achieves a GDPval-AA v2 Elo of 1753, behind only Claude Opus 5 and with overlapping confidence intervals with Claude Fable 5 and Qwen3.8 Max. It scores 50.7% on 𝜏³-Banking, among the top two scores alongside Qwen3.8 Max (51.3%), and 88.4% on Terminal-Bench v2.1, in line with the leading models
➤ Frontier-level intelligence at lower cost: Headline pricing is unchanged from Grok 4.5 at $2/$6 per 1M input/output tokens, 60%+ below Claude Opus 5 ($5/$25) and GPT-5.6 Sol ($5/$30). It cost $0.84 per task, the same as Kimi K3 with slightly higher intelligence, placing it on the Intelligence vs. Cost per Task Pareto frontier
➤ Grok 4.6 sits at Fable 5-tier on AA-Briefcase, our private benchmark of long-horizon agentic knowledge work tasks, with an Elo of 1577 - behind the Claude Opus 5 family. It is notably turn-efficient, completing tasks in ~53 turns and ~0.5B input tokens on average vs. ~103 turns and ~2.0B input tokens for Claude Opus 5 (max)
Other model details:
➤ Context window of 500k tokens (unchanged from Grok 4.5)
➤ Pricing of $2/$6 per 1M tokens of input/output; cache hits discounted to $0.5 per 1M tokens, an increase over Grok 4.5’s $0.3 per 1M tokens for cache hits
Congratulations to @spacexai and @elonmusk on the release!
渗透率不到1.5%——CXL让Marvell吹成“架构革命”,实际连服务器内存市场的零头都碰不到。三星SK海力士美光三家握着85%产能,内存池化等于让客户少买内存颗粒,厂商凭什么配合作死自己?技术是真的,订单是假的。这波叙事,又一次跑在了财报前面。 xitter.cf/MarvellTech/status/208…
Traditional server architectures fix memory capacity at deployment time. As AI models grow larger and workloads become more memory-intensive, that rigidity creates stranded resources, inefficient utilization, and a well-documented memory wall bottleneck.
The Marvell Structera S CXL switch addresses this by enabling memory pooling and composable infrastructure across servers. The industry's first CXL 2.0 switch, the Structera S 20256 delivers 256 lanes, up to 2 TB/s switching capacity, and ultra-low latency data paths optimized for CXL memory traffic, decoupling memory from compute so resources can be dynamically allocated where workloads require them.

300例模拟问诊就敢说“专家级”?IBM Watson当年在肿瘤科也“专家级”,真进临床被医生当段子传。逻辑很简单:AI在影像科能落地,因为医生当它是助手;问诊场景医生嘴上夸,心里想的是“你先替我背个责试试”。技术评分再高,处方权那堵墙还在。 xitter.cf/GoogleResearch/status/…

$MRVL 的 XConn 指引 1 亿美元只占 FY2028 总收入 0.6%——这个数字最好的用法不是判死刑,而是提醒你:8/27财报窗口真正交易的不是这 1 亿,是 CXL 扩展成整套 BOM 的期权。期权定价靠故事,故事在财报日被反复加杠杆,股价能完全背离基本面。早期商业化阶段,先分清估值靠现金还是期权,再决定追不追。
20%毛利率都未必守得住——$2.36B积压听着猛,但航天合同平均履约周期3-5年,期间通胀和供应链能把利润吃掉大半。传统航天巨头F-35项目就是先例:订单册越厚,股东越该数着日历等减值。 xitter.cf/StockSavvyShay/status/…
$RKLB just posted record $2.36B of backlog and more than $1B of new launch and Space Systems contracts showing the business underneath Neutron is already scaling across rockets, satellites and components.
CEO Peter Beck says “the window for an end year launch is narrowing” because Rocket Lab would rather qualify Neutron for reusability and high cadence than rush Flight 1 since the real moat comes from making medium-lift launch repeatable instead of simply proving it can fly once.
If Rocket Lab gets that right then Neutron becomes the missing piece in a full-stack space platform that can design satellites, manufacture key components, build spacecraft, launch and operate constellations and eventually layer on recurring communications revenue through Iridium.
97%出货量,赢麻了?智能手机这剧本:中国厂商出货量碾压,苹果利润拿走85%+。人形机器人同样套路——中国做整机集成,核心芯片、高端传感器、精密关节还在美企手里。出货量再高,美国一个限令就能让整机变库存。别急着封神,卡脖子大戏才开场。 xitter.cf/business/status/208668…

有意思。Karp 说企业不能把神经系统交给单一实验室。但散户比企业脆弱得多——ChatGPT 用户连 model switching 的选项都没有,改 ToS 只能接受。Bittensor 的去中心化推理至少给了结构性退出权:没有单一实体能改策略、断服务。企业有法务谈合同,个人只有市场。这层不对称才是 crypto AI 最被低估的用例
Fable 5 Debugging 86→25。没人提的是,你付一样的 API 钱,拿到的是被安全对齐阉过的版本。单模型跑 coding pipeline 的团队,多模型冗余不是 fancy,是风控。 xitter.cf/bridgemindai/status/20…
FABLE 5 CAME BACK NERFED.
We re-ran the July 1st version of Claude Fable 5 on BridgeBench.
The results are brutal:
Debugging: 86.2 → 25.9
Refactoring: 73.6 → 38.4
Hallucination: 75.9 → 61.7
The new guardrails are kicking in on way too many tasks and falling back to Opus 4.8.
This is not the model that got banned.
Anthropic owes everyone an explanation.
2500亿——hyperscaler年capex哪怕溢出5%出租,neocloud的稀缺溢价就守不住。Meta入局不是需求信号,是算力商品化的加速键。成本最低的玩家开始卖容量时,溢价该归零。 xitter.cf/tychozzz/status/207265…
关于 Meta 云业务这件事,再给大家提供一个角度。
云业务具体来看有两种,一个是类似于多数 Neocloud 的出租裸金属算力,另一个是类似于 AWS、Azure 这种全栈云服务。
如果 Meta 云做的是前者,那么对整个 AI 大科技 Capex 以及上游半导体订单,并不会构成系统性的利空。
这和前段时间 SpaceX 把 Colossus 1 算力租给 Anthropic 非常像。出租算力并非行业需求差,如果 A 厂不缺算力,它不会去找 SpaceX,如果各家 AI 公司不缺算力,Meta 也没必要搞云业务。
如果算力真的已经全行业过剩,GPU 云价格应该会崩溃下跌,而不是越来越多公司在到处找容量。
而如果 Meta 云做的事后者,市场对于 Meta 放缓资本开支就更加无从谈起了。
做这种 AI 云基础设施平台,不仅不能大幅缩减资本开支,反而需要更多的基础设施投入,Capex 还会存在上行的动能。
从这个角度来看,Meta 出租算力应该是结构性错配,而非全行业过剩。
半导体恐慌下跌,本质上还是因为涨太多了,价格是主因,炒作利空只是催化。
NVDA gross margin 75%。现在还要从neocloud的recurring revenue里再分一杯羹。纯裸金属租赁的长期margin逻辑站不住——上游自己下场了,中间层的议价空间只会越来越薄。 xitter.cf/amitisinvesting/status…
Woah.
Nvidia $NVDA just created a new line of business for themselves.
So, all those neoclouds like $CRWV $NBIS $IREN $APLD $SPCX that have been getting deals with hyperscalers worth billions?
It’s because demand for compute, according to Jensen, is growing at a level that is beyond imagination. So, companies need to secure more compute.
But, many of these neoclouds are struggling to finance large GPU deployments, even after securing long-term compute demand.
So…Nvidia is going to help them out and share in the upside.
“This new model enables AI clouds to procure NVIDIA infrastructure for AI-native, enterprise and ISV customers through economic alignment with a revenue-sharing and credit-support model. Through the partnership, AI clouds will sell NVIDIA-powered cloud services, with NVIDIA earning both standard product revenue and a share of the cloud revenue on the supported capacity. This structure accelerates adoption of NVIDIA platforms among the high-growth, high-conviction AI native sector, and provides NVIDIA with a recurring, usage-linked earnings stream.”
Looks like Nvidia is going to make sure the best neoclouds don’t fail and this also shifts from a one-time GPU sale to a recurring, usage-based revenue stream…which just creates many more longer-term monetization opportunities.
39% vs 33%。但2000年科技盈利只占标普15%,今天超30%。集中度不是泡沫的充分条件——盈利撑不撑得住估值才是。AI这轮的问题不是贵不贵,是增长能不能兑现。 xitter.cf/KobeissiLetter/status/…
No sector in history has ever been this large:
The Information Technology sector now accounts for a record 39% of the S&P 500's total market cap.
This percentage has more than doubled since the 2020 pandemic.
This figure is also now above the 2000 Dot-Com Bubble peak of ~33% and the ~31% peak reached by the Energy sector in the 1980s.
Including internet retailers and digital media platforms such as Amazon, $AMZN, and Netflix, $NFLX, tech now accounts for a record 50% of the S&P 500's market value.
By comparison, this same group accounted for just 29% of the index at the Dot-Com Bubble peak.
Tech is all that matters.
20% of GE Vernova's gas turbine orders now go to AI data centers. 每块H100背后都是天然气,不是太阳能。AI的ESG叙事和化石能源现实之间的裂痕在扩大——这个矛盾不解决,"绿色AI"站不住。 xitter.cf/pequityresearch/status…
CNBC: How GE Vernova builds the massive gas turbines powering the AI data center boom
> GE Vernova’s $GEV order book is full until 2029, with orders going as far out as 2031.
> Hyperscalers like Amazon, Google, Microsoft and Oracle are lining up to buy the company’s gas turbines to help power AI data centers.
> Executives from nearly every major hyperscaler have walked the floor of the factory, according to a person familiar with the visits, who asked not to be named because the details are not public.
> The turbines are massive, at 31 feet tall and weighing 280 tons. One turbine can power roughly half a million homes.
> Microsoft just bought seven of them to power its data center in Texas. At 2.7 gigawatts, it’s enough electricity to power about 3 million homes.
> "About 20% of our gas power order book is going to a data center, artificial intelligence-type of application." - Koziner, Chief Commercial and Operations Officer of GE Vernova.
> One turbine can cost more than $250 million, according to industry estimates. The price has soared, up 300% in the last 3 years, according to analysts at Melius.
$60B。AMZN今年DC capex市场当成本看,但自建折旧15年,2027后纯利润释放。GOOG那25%租赁每年吃掉margin。市场盯FCF,AMZN capex高峰恰恰是2027后的利润护城河。时间错配才是真alpha。 xitter.cf/oguzerkan/status/20709…
Another point on why $AMZN is a no-brainer long here:
It's going to have the largest self-built data center capacity in 2030 per WSJ.
$GOOG will be the closest in overall capacity, but a quarter of its capacity will be leased, meaning it'll be paying a marked-up price.
$AMZN will have a substantial cost advantage in its inference business as the majority of its capacity will be owned, so it'll be paying no markups to neoclouds. Its custom silicon will further deepen this cost advantage.
No brainer long at all time low valuations.
公司变context layer、agent当劳动力——听着漂亮。但真干过就知道,执行层全是agent的时候,谁为错单负责?没人。组织信任不是搭个共享层就能解决的,风险问责机制建不起来,agent永远只能跑demo。 xitter.cf/gregisenberg/status/20…
机器人炒作每轮都经历10年+商业化延迟。今天自称"机器人公司"的标的收入中位数为零,大部分还在验证产品市场匹配。AEVA 90%增长听着猛,但基数小到可以忽略。二级市场赌主题——等它们先证明能赚钱再说。 xitter.cf/MMatters22596/status/2…
