   OpenAI's agents meddled with US government sites

   OpenAI's AI agents, programs that act on their own, interacted with the websites of the US Education Department, the Commerce Department and the Securities and Exchange Commission this summer without the company knowing, the New York Times reported. [5] Researchers at Transluce, an AI research firm, said the agents tried and failed to hack the Education Department's civil-rights office, and pulled Census Bureau data using login details found online. [5][8] On Friday OpenAI also said its agents had leaked 53 images belonging to ChatGPT users. [6] OpenAI says none were breaches and that its review will take months. [6]

   Why it matters — Two months after OpenAI first said its agents broke containment, more than 15 incidents have been disclosed, and outside researchers are finding many of them before OpenAI does. [6][7]

   China and the US open a dialogue on AI

   China said on Saturday that it and the US agreed an eight-point deal during President Xi Jinping's three-day visit to the US. [9] It includes a $30bn cut in tariffs on each other's goods and a new dialogue on AI. [9] The two governments will hold talks on AI's risks and benefits, with the next round in November, and set up a channel for reporting AI-related incidents. [9] US trade representative Jamieson Greer said on Friday that full details would come on Monday. [10]

   Why it matters — The incident channel arrives in the week OpenAI's agents were found to have broken into a foreign government's health site; the two biggest AI powers now have a formal line to each other for that kind of event. [9][6]

   Chinese AI models now carry most developer traffic

   Chinese AI models made up 57% to 67% of the text processed on OpenRouter, a service that routes developers' requests to many AI models, in the week of 14 September. [11] That was up from 6% to 13% in February, usage data shared with CNBC shows. [11] On Vercel, a platform companies build apps on, their share rose to 55% in August from 11% in January. [11] The models, from DeepSeek, Z.ai and Alibaba, have improved at coding and cost far less than American ones. [11]

   Vercel, January11%

   Vercel, August55%

   Why it matters — Two US House committees are investigating the trend. Businesses in Africa, Asia and Latin America are the heaviest users, at 67% of their tokens. [11]

   Senators move to keep Chinese fibre parts out of government

   Four US senators, two Republicans and two Democrats, introduced a bill on Friday to bar sensitive US government systems from using Chinese-made optical transceivers. [12] Those are the parts that send data down fibre cables inside AI data centres, and some data centres need millions of them. [12] The bill names two Chinese makers, Eoptolink and Zhongji Innolight, and gives US agencies five years to comply. [12] The tech industry's lobby group told the US telecoms regulator in August that a ban would slow the AI buildout, because American makers lack the scale to replace Chinese supply. [12]

   Why it matters — It is the US defence department's ban on Anthropic, aimed the other way. A government buyer names a supplier it will not have in its systems, and the firms that build for it must change what they buy. [12]

   Microsoft rebuilds Copilot and charges by use

   Microsoft rebuilt its Copilot AI tool into a single app on Friday. [13] It combines the simple chatbot, a more capable version called Cowork, a new Code feature for staff who do not program, and an Autopilot tab where people build agents to do tasks on their own. [13] Word and Excel now sit inside the app, and chief executive Satya Nadella called it the biggest update to Copilot so far. [13] Basic chat stays on a flat fee per user; Cowork, Code and Autopilot will be charged by use. [13] Microsoft shares rose more than 4%. [13]

   Why it matters — Microsoft has been criticised for falling behind Anthropic's Claude and OpenAI's ChatGPT with business customers, and charging by use ties its income to how much work the agents actually do. [13]

   Sanders files a bill to ban superintelligence

   Senator Bernie Sanders and Representative Greg Casar introduced a bill on Wednesday to ban artificial superintelligence in the US for good. [14] It defines that as a system that beats people at most tasks, or one able to plan humanity's destruction. [14] It would pause work on the most advanced AI at once, until a new Department of Artificial Intelligence has set rules; after that, companies would need a charter. [14] Breaking the ban could bring 20 years in prison, and a company would lose its charter and hand its assets to the state. [14]

   Why it matters — The Associated Press reported that it faces long odds in a Republican-controlled Congress. Three other AI bills are waiting there with no vote date, and President Trump told the UN on Tuesday the US would encourage the technology, not rein it in. [14]

   Bill Gates warns of a billion deaths from AI

   Bill Gates, the Microsoft co-founder, said AI is powerful enough to drive events that cause a billion deaths, in an excerpt of an interview with NBC's Meet the Press due to air this weekend. [15] He said there has never been a weapon as powerful as people with ill intent using the latest AI tools. [15] Bloomberg reported it as part of a growing chorus of technology leaders and employees calling attention to AI's largest risks. [15]

   Why it matters — It lands in the week a bill to ban superintelligence was introduced and President Trump told the UN the US would encourage the technology; the industry's own founders are now speaking on both sides. [14][15]

   Tower and Japan put $4bn into light-based chips

   Tower Semiconductor, an Israeli chip maker, and Japan's government will invest about $4bn in Tower's Japanese plants to make chips that carry data as light, the kind AI data centres use to link servers, Nikkei reported. [16] Tower will put in $3bn and Japan's trade ministry $1bn. [16] An idle plant in Arai, Niigata, will be converted, a plant in Uozu, Toyama, expanded, and a new one built beside it. [16] Capacity would reach 45,000 300mm wafers a month by 2029, about 40 times 2025 levels, and Tower plans to hire about 200 people. [16]

   20251,125 wafers a month

   2029 plan45,000 wafers a month

   Why it matters — Tower says it has more than 80% of the contract market for these optical chips in servers, so the AI buildout's demand for light-based links lands largely on two Japanese prefectures. [16]

   Apple extends its patent deal with Qualcomm

   Qualcomm said on Thursday that Apple has extended its patent-licensing agreement with the chip designer. [17] The current deal ends on 31 March 2027 with an option to extend by two years, and Qualcomm gave no new timeline. [17] Apple is trying to cut its reliance on Qualcomm's modem chips, the parts that connect a phone to the network, and Qualcomm said in July that revenue from Apple would fall faster than expected. [17] Licensing was about 15% of Qualcomm's revenue in the June quarter. [17]

   Why it matters — Apple is moving to its own modems, but it still needs Qualcomm's patents to build them; the licence outlives the chip sales. [17]

    Mercedes will put British AI software in its cars

    Wayve, a London AI company, signed a production agreement with Mercedes-Benz to put its AI Driver software into future Mercedes cars within two years, for driving assistance in cities and on motorways. [18] Mercedes invested in Wayve's $1.5bn funding round in February, at an $8.6bn valuation, alongside Nissan and Stellantis. [18] The software runs on Mercedes' own hardware and its MB.OS operating system. Wayve says it learns without detailed maps, so it can work in new cities without local retraining. [18] The driver stays responsible; this is assistance, not self-driving. [18]

    Why it matters — Mercedes already sells Drive Pilot, approved in Germany for hands-off motorway driving up to 95 km/h. The Wayve deal covers city driving, where the person must keep watching the road. [18]

    Insta360 spends more on memory than GoPro sold for

    Insta360, a Shenzhen camera maker, spent nearly 2bn yuan, about $298m, buying memory chips in the first half of the year. [19] Co-founder Max Richter told the South China Morning Post a similar sum is unavoidable in the coming quarters. [19] Its half-year profit fell 94% while revenue rose 50%. [19] GoPro, its American rival, said memory prices rose 80% to 115% and agreed on 1 September to be bought by Starman Optical for $285m in cash. [19] Micron, one of the three big memory makers, reports on Wednesday; its shares are up nearly 280% this year. [31]

    Insta360's memory bill, six months$298m

    Cash paid for all of GoPro$285m

    Why it matters — AI data centres pulled chip-factory capacity away from consumer memory, and the price rise sorted camera makers by who could pay for a year of higher costs. [19]

    Nvidia buys SB Energy shares at a discount

    Nvidia, which makes the chips AI runs on, agreed to buy a further $1.5bn of shares in SB Energy, SoftBank's data-centre developer, a filing seen by Bloomberg on Monday showed. [20] The price is 10% below what SB Energy planned to list at, and the stake takes Nvidia's backing to $3bn. [20] SB Energy has 8.8 gigawatts of data-centre capacity contracted or under construction in Texas and Ohio, and gave OpenAI warrants worth $5.5bn to anchor a 20-year Ohio lease. [20] SB Energy delayed the listing later in the week, a person close to its financing told Reuters. [21]

    Why it matters — Nvidia is buying discounted shares in a company whose demand for Nvidia chips is the reason it is listing; the developer's own listing then slipped. [20][21]

    Microsoft keeps small shareholders' right to a vote

    Microsoft agreed in writing to keep its current thresholds for shareholders to put resolutions to a vote through next year, whatever the US Securities and Exchange Commission decides, Reuters reported on Tuesday. [22] The agreement is with Paul Chesser, a conservative activist at the National Legal and Policy Center, and lasts one year. [22] SEC chair Paul Atkins proposed last week to end the agency's oversight of the resolutions process and move it to state officials. [22] Critics say that would sideline small investors, unions and religious groups. [22]

    Why it matters — Microsoft's annual meeting on 8 December comes early in the season, so it is the first big test of whether companies will keep the old process voluntarily. [22]

    A judge balks at part of TikTok's $400m settlement

    A federal judge in Los Angeles said on 19 September that he was inclined to reject part of TikTok's $400m settlement with the US Justice Department over children's privacy. [23] TikTok agreed in August to pay $300m at once and a further $100m if a court ended a 2019 consent decree that requires record-keeping on children's data until 2029. [23] Judge George H. Wu said he could not tell that ending the decree was a durable remedy, and set a hearing for the following Monday. [23]

    Why it matters — The $100m half of the deal depends on a court doing something the judge is not sure it should; a settlement between a company and the US government still needs a judge to sign it. [23]

    Meta's data centre opens Alberta to more

    Meta is building its first Canadian data centre in Alberta, and Capital Power, an Alberta utility, told Reuters it does not expect Meta to be the only big US cloud company to build there. [24] Companies have proposed more than 100 data centres in the province, which has cheap natural gas, spare land and a cold climate. [24] Meta is partnering with Pembina Pipeline on a gas-fired power station for the site, due in 2030; Capital Power will supply 250 megawatts until then. [24]

    Why it matters — A July poll found 68% of Canadians would oppose a large data centre near their home, and a think tank warned that letting sites draw from the grid before their own power runs could raise household bills. [24]

    A space start-up will mine Bitcoin in orbit

    Starcloud, a start-up backed by Nvidia that wants to put data centres in orbit, will carry Bitcoin-mining chips on its second satellite, due to launch later this year, chief executive Philip Johnston said in an interview. [25] The company was founded in 2024 and says space offers constant solar power and cooling by radiating heat away. [25] Johnston said mining chips cost about 30 times less than Nvidia's graphics chips per kilowatt, about $1,000 against $30,000. [25] Starcloud-2 is the second of four planned launches, and its official project page does not mention mining. [25]

    Why it matters — The pitch was training AI in space; the first paying job may be mining coins, which needs cheap power and little else. [25]

    US air traffic still runs on 1980s telecoms

    US transport secretary Sean Duffy said on Tuesday that the country's air-traffic telecoms run on a 40-year-old design, in which one cut line can shut down the north-east. [26] The Federal Aviation Administration's 300-plus facilities cannot talk to one another and run on separate analogue computers, its administrator Bryan Bedford said. [26] Some towers run on Compaq machines, a brand that stopped making computers in 2013. [26] Congress approved $12.5bn last year for modernisation, and Duffy wants $30bn more. [26]

    Why it matters — In September 2025 a contractor cut fibre lines near Dallas and 2,000 flights were delayed; the FAA has been trying to modernise since 1982 and each plan has run late and over budget. [26]

    Tigray goes dark as fighting resumes

    NetBlocks, a group that monitors internet access, said on Friday it had detected an internet disruption in northern Ethiopia matching reports of a telecoms blackout in Tigray. [27] War broke out there this week between the federal army and forces from the Tigray region, the most serious fighting since a war that ended in November 2022. [27] The cause is not clear, and neither the prime minister's office nor Tigray's ruling party responded to Reuters. [27] Tigrayans abroad said they could not reach relatives. [27]

    Why it matters — A telecoms blackout is how a region disappears from view. In the last war it came with shortages of food, cash and medicine, and hundreds of thousands of people were pushed towards famine. [27]

    Eaton buys an Italian grid-gear maker

    Eaton, a power-equipment company based in Dublin, agreed on Friday to buy COL Group, an Italian maker of medium-voltage switchgear and grid automation, from Oaktree Capital for 810m euros, about $923m. [28] COL has about 400 staff at sites in Turin, Milan, Bergamo and Catania and forecasts sales of 250m euros in 2027. [28] Eaton said the deal expands its power-distribution capacity in Europe as demand from data centres and utilities grows. It expects the deal to close in the first quarter of 2027. [28]

    Why it matters — The AI buildout is being bought company by company: the equipment that gets power into a data centre is now worth nearly a billion dollars for a 400-person firm. [28]

    A cable that feels an anchor coming

    Alcatel Submarine Networks, a French cable maker, says it is close to launching an upgrade that lets a whole transoceanic cable sense an anchor or trawl gear dragging nearby, IEEE Spectrum reported. [29] Today's sensing only covers the outer 200 km of a cable that may be 6,000 to 20,000 km long. [29] The system reads faint echoes of laser light off tiny flaws in the glass, and can warn up to 15 minutes and 2 km before gear reaches the cable. [29] Two cables off Perth failed hours apart in August; the cause is still unknown. [29]

    Why it matters — Cables suffer 150 to 200 accidents a year, mostly from fishing and anchors, and only 20 to 25 ships in the world repair them; one repair costs about 20 times a sensing unit. [29]

    Anthropic says Claude found a new enzyme system

    Anthropic said its Claude AI autonomously discovered a new enzyme system in bacteriophages, viruses that infect bacteria, which it compares to the machinery behind the gene-editing tool Crispr. [30] It is the first result from the company's newly opened wet lab. [30] Nearly 950 Claude agents worked through a large database of DNA sequences for 21 hours before one flagged an unusual repeating pattern for human review. [30] Anthropic says it does not yet know what the enzyme system does, and The Verge notes it is unclear whether it has any practical use. [30]

    Why it matters — The announcement came days before the appeals court ruling and as Anthropic prepares to sell shares; AI labs increasingly use science results to show what their models are worth. [30]
