@Jason @buccocapital I see your angle but have a hard time believing that the median voter in a swing state would have changed their vote with this knowledge

[Jack Moore @Jack_S_Moore]

@Jason @buccocapital What difference would it have made before the midterms?

"Opus 5.5 is a masterpiece." 🚀

[Elon Musk @elonmusk]

@Dimdv99 @tetsuoai Not as good. Opus 5.5 is a masterpiece.

But Grok 5 should exceed Opus 5.5 and maybe that happens in 2 or 3 months, with continued acceleration thereafter.

Excellent analysis that aged well. We need stronger export controls on advanced chips and executives that won't fall for honeytraps.

On a June night in 2024, Nvidia CEO Jensen Huang held court with several of his company’s major Asian customers at a bar in Taipei. Next to him was Huang Xiaole (黄小乐) aka Alice Huang, an executive of Megaspeed, a shady Singapore-based data center company.

Nvidia’s compliance team has looked into Megaspeed and determined it’s “wholly owned and operated by a company based and headquartered outside China, with no China shareholder.”

Megaspeed was created in 2023 when 🇨🇳 7Road, a gaming company with ties to 🇨🇳 state-backed investors, split off its overseas operation in Singapore and renamed it Megaspeed, which in early 2024 set up Speedmatrix, a subsidiary in Malaysia that quickly snapped up ~$2B worth of Nvidia’s most advanced chips. Most of those chips came from Aivres, the US subsidiary of 🇨🇳 Inspur, a major tech company added to the 🇺🇸 Entity List in 2023 for supporting 🇨🇳 military 👉🏻 Nvidia is barred from selling its technology to Inspur without a special license. But since Aivres is based in California and records sales as a US company, it can buy Nvidia chips freely.

Megaspeed has funneled those chips to data centers in Malaysia and Indonesia that appear to remotely serve customers in China. That is not necessarily illegal, but it can be found unlawful if it is done on behalf of a 🇨🇳 company. US officials have also been scrutinizing whether Megaspeed diverted some of those chips on to China, in violation of US law.

Megaspeed is also facing scrutiny from Singaporean police.

Megaspeed listed Alice Huang as its managing director for its first 8 months, and its current director James Tan is from Singapore but is based in Shanghai.

It’s not clear when Jensen Huang and Alice Huang, who are not related, first met. She was mingling with a crowd of tech executives just after midnight at the Taipei bar in early June 2024 when she offered to ask Jensen Huang to join them.

“I bet you guys I can get Jensen here,” she said, and shortly afterwards Jensen Huang arrived in his trademark black leather jacket and drank a whiskey shot with the group.

Jensen Huang and Alice Huang were photographed together again in May, exiting a restaurant in Taipei with an Nvidia aide after a business dinner with other AI suppliers.

Alice Huang spent much of her career in China, including working as a TV reporter for 🇨🇳 state media and as a private banker. Huang left Megaspeed in recent months. It’s unclear when and why she left and what she’s doing now.

Both she and 🇨🇳 7Road, the Chinese company that Megaspeed split off from, have close ties to a web of wealthy investors and tech companies with data center projects in China.

The owners of 7Road include 🇨🇳 central government and several local governments. Before joining Megaspeed, Ms. Huang was executive director for a Shanghai-based fund that had invested in 7Road and had ties to state-backed firms.

Reporters looking into Megaspeed’s opaque operation have tracked business listings that led to a Malaysian data center and shopping mall, a near-empty office in Singapore and a dilapidated storefront outside Kuala Lumpur.

It’s not clear where Megaspeed’s billions of dollars came from. But a few weeks after the gathering in Taipei last year, Megaspeed began receiving a steady supply of multimillion dollar shipments of some of Nvidia’s most advanced chips.

Over the next 3 months, Megaspeed bought a billion $ of Nvidia technology. Within the next 9 months, it secured roughly a billion $ more. The bulk of those advanced Nvidia chips were purchased from 🇨🇳 Inspur’s US subsidiary Aivres. The shipments went to Megaspeed’s Malaysian subsidiary Speedmatrix.

The registered address for Speedmatrix on the shipping records led to a dilapidated storefront outside Kuala Lumpur, where the sign out front advertised a construction company. No one was inside when a reporter visited the address in late Sep. Employees at the law firm next door said they rarely saw people in the office.

@Jason Thanks JCal

Introducing Claude Fable 5.2 and Claude Mythos 5.2, designed to tackle the most daunting technical challenges.

They’re capable collaborators on ambitious projects in many fields, and show improvements in areas like coding, reasoning, and vision.

[Jack Moore @Jack_S_Moore]

@claudeai Having used the Beta extensively, I'm extremely excited for this 💰

[Jack Moore @Jack_S_Moore]

@Jason @TheDemocrats Every American should get quality health care at low / reasonable costs. AI can innovate to drive down costs, and responsible policies around data centers can expand healthcare access.

[Jack Moore @Jack_S_Moore]

@clavicular oh no

[Jack Moore @Jack_S_Moore]

@boardyai Hi Boardy 👋

[Jack Moore @Jack_S_Moore]

Great change for Ultra subscribers. I run most long term projects on Opus 5.5 and it'll be nice not to worry about the 5 hour limits anymore.

[Claude @claudeai]

We’re renaming our Max plans:

Max 5x → Max
Max 20x → Ultra

Max is still $100/month, and Ultra is still $200. If you’re a subscriber, there’s nothing you need to do.

We’re also removing the 5-hour limit for verified Ultra accounts, starting today with most existing subscribers. Newer accounts keep a temporary limit until they’re verified, which helps us prevent fraud and abuse. You'll get an email when it's removed.

Weekly limits remain unchanged. View our plans here: https://t.co/niRpyGF5Me

Very excited for this founding team and the impact we'll see from built world model 🚀

[Andy Elder @AndyElder11]

Today @arjunmathur_ and I are introducing Dream.

We’re announcing $17M in seed funding from @a16z , @svangel , @xyz_vc , and @ziggcap.

@dreamhq is developing a new class of models trained to reason about physical space: its geometry, its constraints, and the relationships between objects and the spaces that contain them. With these models, AI can make a real impact in the $13 trillion architecture, engineering, and construction (AEC) industry for the first time.

@claudeai Claude on iPhone Duo goes so hard

[Jack Moore @Jack_S_Moore]

@rabois Glad we could help Keith 🏃
