A memory shortage is now setting the price of Chinese AI compute, and California just created the job of auditing AI. Both stories are about the same thing: inputs and oversight that nobody can source cheaply. Huawei has raised the indicated price of its Ascend 950DT accelerator to more than 250,000 yuan — about $37,000 — a jump of 20% to 50% from quotes it gave customers just two months ago.

Two regulatory threads and one infrastructure bet: Washington is asking whether Nvidia's biggest chip deal was structured to stay under the merger radar, Massachusetts just made data centers pay for their own clean power, and JD.com is building a 100,000-GPU cluster on Chinese silicon. The Justice Department is investigating whether Nvidia structured its licensing deal with AI chip startup Groq to avoid antitrust scrutiny, the New York Times reported, citing two people familiar with the…

Cognition has finally published how its record factorization happened, and the answer is more interesting than the record: an engineer with no expertise in the math pointed a fleet of coding agents at a spare-compute problem and got a world-first in three weeks. Cognition engineer Eric Lu posted the write-up we asked for: RSA-260, the largest number from RSA Laboratories' 1991 challenge ever cracked, fell in about three weeks of part-time work at an estimated 4,900 GPU-days — roughly $400,000…

Two strands of the AI buildout surfaced this afternoon: OpenAI describing how far its silicon work with Samsung has actually gone, and a fresh challenge to the jobs story that countries are using to justify data centers. OpenAI says joint chip production and research is now the deepest part of its relationship with Samsung.

Jensen Huang says Nvidia's compute is "fungible, durable and highly rentable." One of Wall Street's best-known short sellers heard that and asked the obvious question: then why are you selling it? Two days later the argument has become the cleanest framing yet for the AI capex question. Jim Chanos, who called Enron, replied to Huang's X post with four words that cut straight to the accounting: "Then why not rent them out yourself?

Two big infrastructure moves and one surveillance story you should read in full. Here's the midday round. Qualcomm and Amazon signed a multi-generational chip deal, and Amazon got an option to buy roughly $4 billion of Qualcomm stock as part of it. Per a regulatory filing, the warrant lets Amazon buy shares at $161.26 and is tied to as much as $60 billion of business under the agreement.

The chip supply chain just locked in its next decade. Two of the three biggest buyers of advanced lithography committed to ASML's High NA EUV tools on the same day, and AI is the reason both gave. The world's two largest chipmakers have both committed to ASML's High NA EUV lithography machines, ending years of speculation about whether the industry's most expensive tool would ever reach volume production.

China's AI chip boom is now a retail phenomenon, a small open model quietly topped its weight class, and the UN's human rights chief used the words "existential risk" without hedging. Enflame Technology priced its Shanghai STAR Market IPO at 142.18 yuan a share, raising 6.12 billion yuan — about $908 million — and the retail tranche was subscribed into oblivion.

Two Chinese releases this morning bracket the same bet — that models and agent products can be built without American chips — plus a security firm's answer to the coding-agent mess we covered overnight. iFlytek released Spark X2.5, a 293B-parameter mixture-of-experts model with about 30B active, and the headline claim is not the size — it's the hardware.

Two days after OpenAI shipped Astra, the CEO who sells the silicon just put his own weight behind the AGI claim — and the pushback arrived the same evening. Also: the Nubia NaviX Ultra clears its last regulatory hurdle with Chinese memory inside. Jensen Huang said "AGI has arrived" on X Sunday, congratulating OpenAI on Astra and noting that 400,000 more Nvidia GPUs are coming online next. "From ChatGPT to o1 to Astra in 4 years," he wrote.

Anthropic, Meta, Google, and OpenAI all dropped model updates in a single week — and Nvidia announced a $12.9 billion Hugging Face acquisition on top of it. Meanwhile, NYT reports AI wiped out Kenya's 40,000-person essay-writing industry in two years. Anthropic, OpenAI, Meta, and Google all shipped model updates in the same week — and the industry is starting to feel the whiplash.

The late round: Broadcom turns VMware into an AI factory with governance bolted on, DigiCert's own survey shows post-quantum work stuck in first gear, and a 24-minute deep dive into the hash tables inside Go's most-used data structure. Broadcom used VMware Explore to launch an AI Factory aimed squarely at the on-premises buildout — and paired it with a control plane for agents.
