French AI lab Mistral publishes the weights of Mistral Large 4, its largest model

Mistral has released the weights of Mistral Large 4, which it also calls Le Chonk. Weights are the numbers that make up a model, so anyone can download and run it. Mistral says it is a 1 trillion-parameter mixture-of-experts model. Only about 49 billion parameters are used for each token, because each token goes to just 4 of 128 expert sub-networks. It reads text and images, writes text, handles a context of up to 1 million tokens and has three reasoning levels: low, medium and high. Mistral says it trained the model from scratch on 3,800 Nvidia Grace Blackwell GPUs in its own European data centres, and that it works in more than 160 languages. Mistral says it does especially well on cybersecurity, finance and law work, and TechCrunch notes the company is pitching it to organisations that want control over their cyber defences. It is also available through Mistral's own API.

DoorDash agrees to buy grocery delivery app Instacart for about $17 billion

Food delivery company DoorDash says it will buy Instacart in a deal worth about $17 billion. It will pay $65 per share, 26% more than Instacart's closing price on October 22, and at least 75% of the payment will be cash. Instacart's board approved the deal unanimously. DoorDash says it plans to keep Instacart's brand and app. It also says DashPass and Instacart+ members would pay one membership fee instead of two, and that grocers would stay free to use other delivery platforms. Instacart CEO Chris Rogers said it would make 'online grocery more seamless and affordable'. Until the deal closes, the two run as separate companies.

Alphabet loses a record $500 billion in value as AI answers slow its search growth

The Register reports that Google's search revenue rose 12% from a year earlier to $63.25 billion in the third quarter. A year earlier it grew 14.5%. Google put the slowdown down to 'lower monetization' in AI Mode, its AI answer feature in Search. The Financial Times reports Alphabet's stock fell more than 12%, wiping a record $500 billion off its market value, after it reported negative cash flow amid its AI spending. Ars Technica puts that negative cash flow at $9.06 billion. Bloomberg reports Alphabet disclosed more than $1 trillion in purchase commitments, future leases and other obligations. Google plans to make up the gap with more ads, including bringing ads in AI Mode to international markets.

Amazon's record profit margin is overshadowed by $77 billion of quarterly spending

Amazon says third-quarter revenue rose 12% from a year earlier to $201.9 billion. Operating income rose 61% to $28.1 billion, a 13.9% margin that Amazon says is its highest ever. CNBC reports its cloud arm AWS grew revenue 39% to $45.98 billion and operating income 55% to $17.77 billion, both above analyst estimates. Net income fell 2% to $20.7 billion. Bloomberg reports Amazon spent more than $77 billion on property and equipment in the quarter, leaving a free cash outflow of $42.4 billion; in July Amazon said it would likely spend $220 billion this year. CNBC reports ad revenue rose 11% to $19.64 billion, below the $20.82 billion analysts expected. CEO Andy Jassy said AWS will become a $1 trillion business, but that it will have to keep spending heavily first, TechCrunch reports. The shares fell more than 8% after hours.

Intel's server chip sales jump 78%, but a weak forecast drops its shares 16%

Intel says third-quarter revenue was $16.5 billion, up 21% from a year earlier. Its Data Center and AI unit grew 78% to $7.3 billion, which CFO David Zinsner called the strongest data centre growth in 15 years. Sales of PC chips fell 5% to $8.1 billion, and the foundry unit, which makes chips, grew 58% to $6.7 billion. Intel expects fourth-quarter revenue of $15 billion to $16 billion and says the PC slowdown will last at least through the first half of next year. CEO Lip-Bu Tan said the priority is more supply for its Xeon server chips. On the earnings call, Intel said its budget Wildcat Lake laptop chips are sold out, The Verge reports. Tom's Hardware reports Intel is taking some Panther Lake laptop chip capacity offline to build more Granite Rapids server chips, and that its next desktop chips, Nova Lake, will be the first to use its 18A-P manufacturing process. CNBC reports the forecast was below estimates and the shares fell more than 16% after hours.

US Homeland Security staff leak came from a claimed hack of its Okta login system

Wired reports that personal data of more than 41,000 employees and contractors at the US Department of Homeland Security has leaked online, including CBP and ICE agents. The hackers claim they got in through the department's Okta login system. The records include the locations of ICE and CBP facilities and workers' cell phone numbers. Ars Technica reports the leak also reveals undercover agents. Social network Bluesky has blocked links to the leaked archive, saying it was shared without the workers' authorization.

Reddit will require people to log in to read the site, citing AI scraping

Reddit CEO Steve Huffman confirmed in a letter to shareholders that the site is moving to 'a logged-in-only experience', Ars Technica reports. He said it gives Reddit more signals for ad targeting and protects its data from AI scraping. Reddit will test the requirement in some markets outside the US this quarter. Huffman wrote that search referrals fell by more than 1 million a week on average in October, and that daily users could fall in the fourth quarter by a low-double-digit percentage if that continues. He also said Google's AI Mode 'does not drive traffic', The Verge reports. CNBC reports revenue rose 53% to $895 million, above estimates, while daily users grew 12% to 130.3 million, below estimates. Its fourth-quarter forecast was also below estimates, and the shares fell more than 17% after hours.

Report: an alleged Chinese spy built a close relationship with Nvidia's CEO

The New York Times reports that US intelligence concluded Alice Huang, an executive at Singapore cloud company Megaspeed, was passing information to Beijing. Megaspeed is an Nvidia customer that US authorities are investigating over suspected smuggling of Nvidia chips into China. US surveillance identified Nvidia CEO Jensen Huang as one of her contacts. The report offers no evidence he knew of her alleged activities, though some senior officials now doubt he could have been unaware. The Times says President Trump was briefed about a year ago and chose not to act. Nvidia says the meetings were normal customer contact and that the smuggling claims were investigated and debunked last year.
