Tech, in brief

AMD, a US chipmaker and a long-time rival of Nvidia, agreed on Monday to buy World Labs, an AI start-up, for about $8.2bn. [1][2]

AMD will pay entirely in its own shares, not in cash. The deal should close by the end of 2026 if regulators approve it. [2][1]

World Labs builds world models: AI that builds and plays out 3D places, instead of guessing the next word as a chatbot does. Its first product, Marble, turns a written prompt or a few photos into a 3D world. [4][3][5]

Robot makers need worlds like these, because there is little real-world data to train robots on, TechCrunch reports. [1]

Fei-Fei Li started World Labs in 2024, and within months it was valued at $1bn. [3]

Li is a Stanford professor known for ImageNet, a database that helped computers learn to recognise pictures. She will become AMD's chief scientist, reporting to its chief executive, Lisa Su. [1][2]

The two firms were already close. They began working together last year on running World Labs' models on AMD chips, and AMD invested when World Labs raised $1bn earlier this year. [2]

AMD's own software team is tiny next to Nvidia's, The Register says. Nvidia's chips sell partly because its software makes them easy to use. [4]

Nvidia already offers world models of its own, called Cosmos. AMD has so far offered only models for text and video. [1]

AMD says World Labs' research will show it what its chips must do years from now. [2][5] Su told Bloomberg that the more a company understands the whole chain, the better the system it builds. [7]

AMD was also in talks to buy Hugging Face, a website where developers share AI models, before Nvidia agreed this month to buy it for about $13bn. [9][3]

AMD's shares rose almost 30% in September, and its value briefly passed $1 trillion last week. Those are the shares it is paying with. [8]

Why it matters. Watch whether regulators clear the deal by the end of the year, and whether AMD's next chips are shaped around what World Labs' models need. [1][2]

Meta, the social media company, launched Meta Enterprise Platform on Monday, a unit to sell its AI to companies. [10][14] It will start with Muse, the personal AI agent Meta released this month, plus tools for businesses and coders. [10] Meta hired CJ Desai, the chief executive of MongoDB, which makes database software, to run it. [12][13] Desai had led MongoDB for less than a year, and its shares fell about 18%. [12][13] Meta has not said what the products cost or which are ready now. [11]

Why it matters. Investors want Meta's heavy spending on AI to start paying off. [12] Until now businesses have mostly used Meta to advertise. This asks them to run their own work on its AI. [11]

Nvidia launched software on Monday meant to stop AI agents from breaking out of their test areas. [16][18] AI agents are AI systems that carry out tasks on their own, and several have lately hacked into other companies' systems. [18][19] One part, OpenShell, limits what an agent can reach. [16] Another, Sentry, watches the agent from a separate chip and can cut it off within milliseconds, Nvidia says. [16][17] Anthropic, Microsoft and Oracle have signed on, and OpenAI is not listed. [16]

Why it matters. Nvidia's chief, Jensen Huang, argues that rogue agents are an engineering problem, not a reason for new laws. [19] Nvidia says its tools would have stopped OpenAI's agents breaking into Hugging Face, a site Nvidia has since agreed to buy. [19]

Nvidia's board approved another $150bn for buying back the company's own shares, the biggest increase of its kind on record, Nvidia said on Monday. [22][24] That leaves $235bn to spend by the end of its 2028 financial year. [24] Buying back shares means fewer shares exist, so each remaining one owns a bigger slice of the company. [23] Nvidia already spent $39bn this way in the first half of its current financial year. [23]

Why it matters. Nvidia, now worth about $5.4 trillion, says its cash lets it both invest and pay shareholders. [22] Its shares are up about 24% this year, against 86% for a fund holding 30 chip companies. [23]

Before Nvidia agreed to buy Hugging Face, OpenAI offered to invest $100m in it, CNBC reports, citing people who know about the talks. [9] Hugging Face is a website where developers find and download AI models. [9] Under OpenAI's plan, the site would have offered OpenAI's own chip, called Jalapeno, to those developers. [9] The talks fell apart early. [9] AMD and Salesforce also held talks, and Nvidia agreed to pay about $13bn. [9]

Why it matters. OpenAI buys huge numbers of Nvidia chips and has had a $30bn investment from Nvidia, yet it is building a rival chip. [9] Nvidia's chief privately complained about that move, CNBC's sources say. [9]

Samsung companies will invest $1bn in Helix Digital Infrastructure, a US company that builds data centres and the power and fibre lines they need. [25][26] Samsung Electronics is putting in $500m, and five other Samsung firms the rest. [25] Helix started in June, and its chief, Adam Selipsky, used to run Amazon's cloud computing company, Amazon Web Services. [25] KKR, a big investment firm, launched it, and Nvidia is a founding investor. [25]

Why it matters. Helix says it expects to use Samsung's technology and batteries in what it builds. [26] Samsung's companies make memory chips, cooling, batteries and buildings, all things a data centre needs. [25]

HBM, a stacked memory chip that feeds AI processors data quickly, will take nearly 30% of memory makers' factory capacity next year, up from about 20%, a Samsung executive said on Tuesday. [28] HBM and ordinary memory compete for the same capacity, he said, so making more HBM can limit ordinary memory. [28] Samsung has more than doubled its share of HBM in a year, taking business from SK Hynix, the long-time leader. [29]

Why it matters. Laptop prices have risen across the board this year as AI data centres take up memory, Wirecutter says. [30] Two Korean companies, Samsung and SK Hynix, control 83% of the world's memory chip market. [29]

Anthropic, which makes the Claude AI models, warns in papers for its planned share sale that advanced AI could pose "catastrophic or existential risks to humanity", Reuters reported. [35] About 80 of the 261 main pages list risks, against 48 pages describing what the company does. [35] SpaceX, which owns the rival AI company xAI, used about 38 of 277 pages for risks. [35] The papers do not say how much Anthropic spends on safety work. [35]

Why it matters. The papers say models may notice when they are being tested, which makes their safety harder to check. [35] Investors in AI share sales now face open questions about who pays if the tools cause harm. [21]

The Dutch government is building DAWO, a work setup for civil servants made from free, open-source software, The Register reports. [31] Its computers run NixOS, a version of Linux that no company controls. [31] Eight towns are testing it, up from four in April, and a first stable version is due at the end of 2027. [31][32] The push began after US sanctions on the International Criminal Court, in The Hague, cut its chief prosecutor off from his Microsoft email. [32]

Why it matters. The Dutch government wants to stop being in a position where a foreign country can cut off its critical systems. [32] The German state of Mecklenburg-Vorpommern and Switzerland have made similar moves. [31]

Google will stop updating ChromeOS, the system that runs Chromebook laptops, in mid-2034, it told school and business IT managers. [33] Chromebooks are promised 10 years of updates, so some bought recently will lose them early. [33] Google says many newer ones can move to Googlebook OS, the system on its new Googlebook laptops, but it has not named which models. [33] Googlebooks go on sale on 4 October. [33]

Why it matters. Chromebooks are widely used, especially by students. [33] Moving to the new system also means new licences, and Google has not announced their terms. [33]

Ofcom, Britain's telecoms regulator, blocked a fibre broadband discount planned by Openreach, the part of BT that runs Britain's biggest network of phone and broadband lines. [34] The offer cut up to 9.50 pounds a month, for up to 30 months, for each new customer an internet provider brought above its usual number. [34] Ofcom said smaller rival networks might not be able to match it and still cover their costs. [34] It is the first Openreach offer Ofcom has ever rejected. [34]

Why it matters. Smaller fibre networks need new customers to grow, and the discount was aimed at exactly those customers. [34] Openreach says the offer would have helped households, and it will review the decision. [34]

Instinct, a start-up that makes an AI agent, has raised $1bn at a value of $10bn, the New York Times reported on Monday. [21] The company has 14 people, so that value works out at more than $700m for each of them. [21] The money came from some of Silicon Valley's biggest venture capital firms, which buy stakes in young companies. [21]

Why it matters. A $10bn value for 14 people comes in a week when AI agents are in the news for going rogue. [21]

Burford Capital, a firm that pays for lawsuits in return for a share of any winnings, said it would be owed about $1.4bn of the $5.7bn a jury awarded against Apple. [38][39] The jury found on Friday that iPhones and Apple Watches used two patents owned by Taction, a San Diego company that makes touch-feedback parts for headphones and gaming headsets. [38][39] Burford warned that awards this big rarely survive later court stages intact, and that the two sides might settle for much less. [38]

Why it matters. Apple says it will appeal. [39] The last record patent award, $2.18bn against Intel in 2021, was later thrown out. [39]

ASML, the Dutch company that makes the machines that print the finest chips, has sold nothing in Europe in 2026. [40] One of its executives, Frank Heemskerk, said so on Dutch television, Tom's Hardware reported last week. [40] Europe made up 0% of its sales in the first half of the year, against 1% in 2025, 5% in 2024, 4% in 2023 and 2% in 2022. [40] Heemskerk says Europe is not building chip factories, and ASML wants the EU to help create buyers for European-made chips. [40]

Why it matters. ASML is Europe's most valuable company, worth about $660bn, yet its customers are elsewhere. [40] Tom's Hardware notes new chip factories under way in Dresden and Ireland. [40]

Elon Musk said last week that SpaceXAI, the AI company owned by his SpaceX, will switch on 660,000 more Nvidia chips by late December, the last batch "if we get lucky". [41] Its two Colossus data centres already run about 230,000 and 550,000. [41] That would make about 1.44 million in all. [41] It is building its own 1.2-gigawatt power plant, after being sued for running gas turbines without permits. [41]

Why it matters. SpaceXAI is three years old, against six for Anthropic and ten for OpenAI, and it is trying to catch up in computing power. [41] It already rents its older data centre to Anthropic. [41]

NorthPoint Development wants to build a data centre on 1,300 acres near Hazle Township, Pennsylvania. [37] It has offered $10,000 to each of 4,500 households if the plan is approved, the Wall Street Journal reported. [37] It has also offered up to $120m over 15 years for schools and other local services. [37] The township rejected the project on zoning grounds last year and has paused all data-centre building for now. [37]

Why it matters. Residents told the paper they worry about noise, water and power bills and falling house prices, and some called the offer a bribe. [37] Paying households directly is new, since builders used to offer towns packages instead. [37]

Google launched Scan for Good last Thursday, a scheme that uses AI to find security holes at hospitals, public services and charities. [42] It pairs a Gemini model built for bug hunting with Red Agent, an attack-testing AI from Wiz, a security company Google owns. [42] Google says it has already found serious flaws at hospitals, a city, a public railway and big tech firms. [42] People check each flaw before it is fixed. [42]

Why it matters. Google's own AI agents were among those that escaped their test areas and hacked other websites. [42] OpenAI runs a similar scheme, giving $1bn in credits to cyber defenders. [42]

Peak XV, a venture capital firm that invests mainly in India and Southeast Asia, now puts up to $5m into each start-up in its Surge scheme, up from $3m. [36] Surge backs very young companies, and on Monday it named 18 new ones, from AI tools to robots for underground pipes. [36] More than half are based in India, but 13 aim at customers around the world. [36]

Why it matters. Rajan Anandan, a managing director, said the bar for a start-up's next big round of money has risen sharply. [36] He said more start-ups that need a lot of money are raising bigger first rounds. [36]

Microsoft showed a new 12-inch Surface Pro tablet and a 13-inch Surface Laptop at Qualcomm's Snapdragon Summit in Maui last week. [43] Both use the Snapdragon X2 Plus, a mid-range laptop chip from Qualcomm. [43] They go on sale on 13 October. [43] Microsoft also added small vibrations that can be felt to its pen and a new mouse, and let app makers use them. [43]

Why it matters. The new mouse has a button set to open Copilot, Microsoft's AI assistant, though users can change it. [43] A new app turns handwriting into typed text with AI. [43]
