New Linux/Android 2-in-1 Tablet 'Open Slate' Announced by Brax Technologies (braxtech.net) 13

Brax Technologies just announced "a privacy-focused alternative to locked-down tablets" called open_slate that can double as a consumer tablet and a Linux-capable workstation on ARM.

Earlier Brax Technologies built the privacy-focused smartphone BraX3, which co-founder Plamen Todorov says proved "a privacy-focused mobile device could be designed, crowdfunded, manufactured, and delivered outside the traditional Big Tech ecosystem." Just as importantly, BraX3 showed us the value of building with the community. The feedback we received — what worked, what didn't, and what people wanted next — played a major role in shaping our direction going forward. Today, we're ready to share the next step in that journey...
They're promising their "2-in-1" open_slate tablet will be built with these guiding principles:
  • Modularity beyond repairability". ("In addition to a user-replaceable battery, it supports an M.2 expansion slot, allowing users to customize storage and configurations to better fit their needs.")
  • Hardware-level privacy and control, with physical switches allowing users to disable key components like wireless radios, sensors, microphones, and cameras.
  • Multi-OS compatibility, supporting "multiple" Android-based operating systems as well as native Linux distributions. ("We're working with partners and the community to ensure proper, long-term OS support rather than one-off ports.")
  • Longevity by design — a tablet that's "supported over time"

Brax has already created an open thread with preliminary design specs. "The planned retail price is 599$ for the base version and 799$ for the Pro version," they write. "We will be offering open_slate (both versions) at a discount during our pre-order campaign, starting as low as 399$ for the base version and 529$ for the Pro version for limited quantities only which may sell out in a day or two from launching pre-orders...

"Pre-orders will open in February, via IndieGoGo. Make sure to subscribe for notifications if you don't want to miss the launch date."

Washington State May Mandate 'Firearm Blueprint Detection Algorithms' For 3D Printers (adafruit.com) 123

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) writes: Washington State lawmakers are proposing bills (HB 2320 and HB 2321) that would require 3D printers and CNC machines to block certain designs using software-based "firearms blueprint detection algorithms." In practice, this means scanning every print file, comparing it against a government-maintained database, and preventing "skilled users" from bypassing the system.

Supporters frame this as a response to untraceable "ghost guns," but even federal prosecutors admit the tools involved are ordinary manufacturing equipment. Critics warn the language is overbroad, technically unworkable, hostile to open source, and likely to push printing toward cloud-locked, subscription-based systems—while doing little to stop criminals.

China Makes Too Many Cars, and the World Is Increasingly OK With It (bloomberg.com) 83

After years of Western governments raising alarms about Chinese automotive overcapacity and erecting tariff barriers, an unexpected pivot is now underway as major economies cautiously open their markets to Chinese electric vehicles, Bloomberg writes. Beijing itself has started acknowledging the problem at home. Chinese regulators last week warned of "severe penalties" for automakers defying efforts to rationalize pricing in the country's car market, and earlier this month a government ministry urged battery makers to curtail expansion and cutthroat competition.

The European Union imposed steep tariffs on Chinese EV imports in 2024 and is now considering replacing them with minimum import price agreements. Canada's Prime Minister Mark Carney last week decided to allow 49,000 Chinese EVs annually at a 6.1% tariff rate, removing a 100% surtax. Germany announced this week that its $3.5 billion EV subsidy program will be open to all manufacturers including Chinese brands. Germany's environment minister Carsten Schneider dismissed concerns during a January 19 press conference: "I cannot see any evidence of this postulated major influx of Chinese car manufacturers in Germany, either in the figures or on the roads."

BYD registered an eightfold increase in sales in Germany last year and pulled ahead of Tesla, though Volkswagen still registered around 2,300 vehicles for every one BYD sold.

Anthropic's AI Keeps Passing Its Own Company's Job Interview (anthropic.com) 39

Anthropic has a problem that most companies would envy: its AI model keeps getting so good, the company wrote in a blog post, that it passes the company's own hiring test for performance engineers. The test, designed in late 2023 by optimization lead Tristan Hume, asks candidates to speed up code running on a simulated computer chip. Over 1,000 people have taken it, and dozens now work at Anthropic. But Claude Opus 4 outperformed most human applicants.

Hume redesigned the test, making it harder. Then Claude Opus 4.5 matched even the best human scores within the two-hour time limit. For his third attempt, Hume abandoned realistic problems entirely and switched to abstract puzzles using a strange, minimal programming language -- something weird enough that Claude struggles with it. Anthropic is now releasing the original test as an open challenge. Beat Claude's best score and ... they want to hear from you.

EU Parliament Calls For Detachment From US Tech Giants (heise.de) 102

The European Parliament is calling on the European Commission to reduce dependence on U.S. tech giants by prioritizing EU-based cloud, AI, and open-source infrastructure. The report frames "European Tech First," public procurement reform, and Public Money, Public Code as necessary self-defense against growing U.S. control over critical digital infrastructure. Heise reports: In terms of content, the report focuses on a strategic reorientation of public procurement and infrastructure. The compromise line adopted stipulates that member states can favor European tech providers in strategic sectors to systematically strengthen the technological capacity of the Community. The Greens even called for a stricter regulation here, where the use of products "Made in EU" should become the rule and exceptions would have to be explicitly justified. They also pushed for a definition for cloud infrastructure that provides for full EU jurisdiction without dependencies on third countries.

With the decision, the MEPs want to lay the foundation for a European digital public infrastructure based on open standards and interoperability. The principle of Public Money, Public Code is anchored as a strategic foundation to reduce dependence on individual providers. Software specifically developed for administration with tax money should therefore be made available to everyone under free licenses. For financing, the Parliament relies on the expansion of public-private investments. A "European Sovereign Tech Fund" endowed with ten billion euros was discussed beforehand, for example, to specifically build strategic infrastructures that the market does not provide on its own. The shadow rapporteur for the Greens, Alexandra Geese, sees Europe ready to take control of its digital future with the vote. As long as European data is held by US providers subject to laws such as the Cloud Act, security in Europe is not guaranteed.

China Lagging in AI Is a 'Fairy Tale,' Mistral CEO Says (msn.com) 57

Claims that Chinese technology for AI lags the US are a "fairy tale," Arthur Mensch, the chief executive officer of Mistral, said. From a report: "China is not behind the West," Mensch said in an interview on Bloomberg Television at the World Economic Forum in Davos, Switzerland on Thursday. The capabilities of China's open-source technology is "probably stressing the CEOs in the US."

The remarks from the boss of one of Europe's leading AI companies diverge from other tech leaders at Davos, who reassured lawmakers and business chiefs that China is behind the cutting edge by months or years.

Wikipedia's Guide to Spotting AI Is Now Being Used To Hide AI 34

Ars Technica's Benj Edwards reports: On Saturday, tech entrepreneur Siqi Chen released an open source plugin for Anthropic's Claude Code AI assistant that instructs the AI model to stop writing like an AI model. Called "Humanizer," the simple prompt plugin feeds Claude a list of 24 language and formatting patterns that Wikipedia editors have listed as chatbot giveaways. Chen published the plugin on GitHub, where it has picked up over 1,600 stars as of Monday. "It's really handy that Wikipedia went and collated a detailed list of 'signs of AI writing,'" Chen wrote on X. "So much so that you can just tell your LLM to... not do that."

The source material is a guide from WikiProject AI Cleanup, a group of Wikipedia editors who have been hunting AI-generated articles since late 2023. French Wikipedia editor Ilyas Lebleu founded the project. The volunteers have tagged over 500 articles for review and, in August 2025, published a formal list of the patterns they kept seeing.

Chen's tool is a "skill file" for Claude Code, Anthropic's terminal-based coding assistant, which involves a Markdown-formatted file that adds a list of written instructions (you can see them here) appended to the prompt fed into the large language model (LLM) that powers the assistant. Unlike a normal system prompt, for example, the skill information is formatted in a standardized way that Claude models are fine-tuned to interpret with more precision than a plain system prompt. (Custom skills require a paid Claude subscription with code execution turned on.)

But as with all AI prompts, language models don't always perfectly follow skill files, so does the Humanizer actually work? In our limited testing, Chen's skill file made the AI agent's output sound less precise and more casual, but it could have some drawbacks: it won't improve factuality and might harm coding ability. [...] Even with its drawbacks, it's ironic that one of the web's most referenced rule sets for detecting AI-assisted writing may help some people subvert it.

Apple Reportedly Replacing Siri Interface With Actual Chatbot Experience For iOS 27 20

According to Bloomberg's Mark Gurman, Apple is reportedly planning a major Siri overhaul in iOS 27 and macOS 27 where the current assistant interface will be replaced with a deeply integrated, ChatGPT-style chatbot experience. "Users will be able to summon the new service the same way they open Siri now, by speaking the 'Siri' command or holding down the side button on their iPhone or iPad," says Gurman. "More significantly, Siri will be integrated into all of the company's core apps, including ones for mail, music, podcasts, TV, Xcode programming software and photos. That will allow users to do much more with just their voice." 9to5Mac reports: The unannounced Siri overhaul will reportedly be revealed at WWDC in June as the flagship feature for iOS 27 and macOS 27. Its release is expected in September when Apple typically ships major software updates. While Apple plans to release an improved version of Siri and Apple Intelligence this spring, that version will use the existing Siri interface. The big difference is that Google's Gemini models will power the intelligence. With the bigger update planned for iOS 27, the iOS 26 upgrade to Siri and Apple Intelligence sounds more like the first step to a long overdue modernization.

Gurman reports that the major Siri overhaul will "allow users to search the web for information, create content, generate images, summarize information and analyze uploaded files" while using "personal data to complete tasks, being able to more easily locate specific files, songs, calendar events and text messages." People are already familiar with conversational interactions with AI, and Bloomberg says the bigger update to Siri will be support both text and voice. Siri already uses these input methods, but there's no real continuity between sessions.

cURL Removes Bug Bounties (etn.se) 39

Ancient Slashdot reader jantangring shares a report from Swedish electronics industry news site Elektroniktidningen (translated to English), writing: "Open source code library cURL is removing the possibility to earn money by reporting bugs, hoping that this will reduce the volume of AI slop reports," reports etn.se. "Joshua Rogers -- AI wielding bug hunter of fame -- thinks it's a great idea." cURL maintainer Daniel Stenberg famously reported on the flood AI-generated bad bug reports last year -- "Death by a thousand slops." Now, cURL is removing the bounty payouts as of the end of January.

"We have to try to brake the flood in order not to drown," says cURL maintainer Daniel Stenberg [...]. "Despite being an AI wielding bug hunter himself, Joshua Rogers -- slasher of a hundred bugs -- thinks removing the bounty money is an excellent idea. [...] I think it's a good move and worth a bigger consideration by others. It's ridiculous that it went on for so long to be honest, and I personally would have pulled the plug long ago," he says to etn.se.

Setapp Mobile To Close in February as Alternative iOS App Store Economics Prove Untenable (macrumors.com) 23

MacPaw, the Ukraine-based developer, has announced that Setapp Mobile -- its alternative iOS app store for European Union users that launched in open beta in September 2024 -- will shut down on February 16, 2026, citing "still-evolving and complex business terms" for alternative marketplaces that don't fit its current business model.

Alternative iOS stores became possible under the Digital Markets Act but face challenges including Apple's controversial Core Technology Fee, which Epic Games CEO Tim Sweeney has called "ruinous for any hopes of a competing store getting a foothold."

Europe Must Invest in Open Source AI or Cede To China, Schmidt Says (bloomberg.com) 65

An anonymous reader shares a report: Europe must invest in its own open source artificial intelligence labs and address soaring energy prices, or it will quickly find itself dependent on Chinese models, former Google chief executive and tech investor Eric Schmidt said.

"In the US, the companies are largely moving to closed source, which means they'll be purchased and licensed and so forth. And it is also the case that China is largely open weight, open source in its approach," Schmidt said at the World Economic Forum in Davos, Switzerland, on Tuesday. "Unless Europe is willing to spend lots of money for European models, Europe will end up using the Chinese models. It's probably not a good outcome for Europe."

'Just Because Linus Torvalds Vibe Codes Doesn't Mean It's a Good Idea' (theregister.com) 61

In an opinion piece for The Register, Steven J. Vaughan-Nichols argues that while "vibe coding" can be fun and occasionally useful for small, throwaway projects, it produces brittle, low-quality code that doesn't scale and ultimately burdens real developers with cleanup and maintenance. An anonymous reader shares an excerpt: Vibe coding got a big boost when everyone's favorite open source programmer, Linux's Linus Torvalds, said he'd been using Google's Antigravity LLM on his toy program AudioNoise, which he uses to create "random digital audio effects" using his "random guitar pedal board design." This is not exactly Linux or even Git, his other famous project, in terms of the level of work. Still, many people reacted to Torvalds' vibe coding as "wow!" It's certainly noteworthy, but has the case for vibe coding really changed?

[...] It's fun, and for small projects, it's productive. However, today's programs are complex and call upon numerous frameworks and resources. Even if your vibe code works, how do you maintain it? Do you know what's going on inside the code? Chances are you don't. Besides, the LLM you used two weeks ago has been replaced with a new version. The exact same prompts that worked then yield different results today. Come to think of it, it's an LLM. The same prompts and the same LLM will give you different results every time you run it. This is asking for disaster.

Just ask Jason Lemkin. He was the guy who used the vibe coding platform Replit, which went "rogue during a code freeze, shut down, and deleted our entire database." Whoops! Yes, Replit and other dedicated vibe programming AIs, such as Cursor and Windsurf, are improving. I'm not at all sure, though, that they've been able to help with those fundamental problems of being fragile and still cannot scale successfully to the demands of production software. It's much worse than that. Just because a program runs doesn't mean it's good. As Ruth Suehle, President of the Apache Software Foundation, commented recently on LinkedIn, naive vibe coders "only know whether the output works or doesn't and don't have the skills to evaluate it past that. The potential results are horrifying."

Why? In another LinkedIn post, Craig McLuckie, co-founder and CEO of Stacklok, wrote: "Today, when we file something as 'good first issue' and in less than 24 hours get absolutely inundated with low-quality vibe-coded slop that takes time away from doing real work. This pattern of 'turning slop into quality code' through the review process hurts productivity and hurts morale." McLuckie continued: "Code volume is going up, but tensions rise as engineers do the fun work with AI, then push responsibilities onto their team to turn slop into production code through structured review."

Germany's EV Subsidies Will Include Chinese Brands (cnevpost.com) 55

Germany is reinstating EV subsidies after a sharp sales drop, rolling out a 3 billion-euro program offering 1,500-6,000 euros per buyer starting in May and running through 2029. Unlike some neighboring countries, the incentives are open to all manufacturers with a focus on low- and middle-income households. From a report: "I cannot see any evidence of this postulated major influx of Chinese car manufacturers in Germany, either in the figures or on the roads -- and that is why we are facing up to the competition and not imposing any restrictions," German Environment Minister Carsten Schneider said at a Monday press conference. The decision is a major boon for affordable Chinese automakers like BYD that are steadily gaining ground in the European market, [Bloomberg noted].

Germany's green-light for Chinese EVs stands in stark contrast to other nations' approaches. In the UK, subsidies introduced last year effectively excluded Chinese battery-powered vehicles, while France's so-called social leasing scheme includes similar restrictions. [...] Germany maintains strong diplomatic ties with China. German automakers are among the most significant players in China's automotive industry. Over the past years, China's policies -- including purchase subsidies and purchase tax reductions -- have not excluded models or automakers from specific countries. Whether German automakers like Volkswagen or American automakers like Tesla, all enjoy national-level purchase incentive policies in China on par with domestic automakers.

Hundreds Answer Europe's 'Public Call for Evidence' on an Open Digital Ecosystem Strategy (helpnetsecurity.com) 30

The European Commission "has opened a public call for evidence on European open digital ecosystems," writes Help Net Security, part of preparations for an upcoming Communication "that will examine the role of open source in EU's digital infrastructure." The consultation runs from January 6 to February 3, 2026. Submissions will be used to shape a Commission Communication addressed to the European Parliament, the Council, and other EU bodies, which is scheduled for publication in the first quarter of 2026... The call for evidence links Europe's reliance on digital technologies developed outside the EU to concerns over long term control of infrastructure and software supply chains... Open digital ecosystems are discussed in the context of technological sovereignty and the use of technologies that can be inspected, adapted, and shared.
Long-time Slashdot reader Elektroschock describes it as the European Commission "stepping up its efforts behind open-source software" Building on President von der Leyen's political guidelines, the initiative will review the Commission's 2020-2023 open-source approach and set out concrete actions to strengthen Europe's open-source ecosystem across key areas such as cloud, AI, cybersecurity and industrial technologies. The strategy will be presented alongside the upcoming Cloud and AI Development Act, forming a broader policy package aimed at reducing strategic dependencies and boosting Europe's digital resilience.
And "In just a few days, over 370 submissions have already been filed, indicating that the issue is touching a nerve across the EU," writes CyberNews.com: "Europe must regain control over its software supply chain to safeguard freedom, security, and innovation," suggests an individual from Slovakia. Similar perspectives appear to be widely shared among respondents...

The document doesn't mention US tech giants specifically, but rather aims to support tech sovereignty and seek "digital solutions that are valid alternatives to proprietary ones...."

"This is not a legislative initiative. The strategy will take the form of a Commission communication. The initiative will set out a general approach and will propose: actions relying on further commitments and an implementation process," the EC explains. Policymakers expect the strategy to help EU member states identify the necessary steps to support national open-source companies and communities.

What Happened After Security Researchers Found 60 Flock Cameras Livestreaming to the Internet (youtube.com) 50

A couple months ago, YouTuber Benn Jordan "found vulnerabilities in some of Flock's license plate reader cameras," reports 404 Media's Jason Koebler. "He reached out to me to tell me he had learned that some of Flock's Condor cameras were left live-streaming to the open internet."

This led to a remarkable article where Koebler confirmed the breach by visiting a Flock surveillance camera mounted on a California traffic signal. ("On my phone, I am watching myself in real time as the camera records and livestreams me — without any password or login — to the open internet... Hundreds of miles away, my colleagues are remotely watching me too through the exposed feed.") Flock left livestreams and administrator control panels for at least 60 of its AI-enabled Condor cameras around the country exposed to the open internet, where anyone could watch them, download 30 days worth of video archive, and change settings, see log files, and run diagnostics. Unlike many of Flock's cameras, which are designed to capture license plates as people drive by, Flock's Condor cameras are pan-tilt-zoom (PTZ) cameras designed to record and track people, not vehicles. Condor cameras can be set to automatically zoom in on people's faces... The exposure was initially discovered by YouTuber and technologist Benn Jordan and was shared with security researcher Jon "GainSec" Gaines, who recently found numerous vulnerabilities in several other models of Flock's automated license plate reader (ALPR) cameras.
Jordan appeared this week as a guest on Koebler's own YouTube channel, while Jordan released a video of his own about the experience. titled "We Hacked Flock Safety Cameras in under 30 Seconds." (Thanks to Slashdot reader beadon for sharing the link.) But together Jordan and 404 Media also created another video three weeks ago titled "The Flock Camera Leak is Like Netflix for Stalkers" which includes footage he says was "completely accessible at the time Flock Safety was telling cities that the devices are secure after they're deployed."

The video decries cities "too lazy to conduct their own security audit or research the efficacy versus risk," but also calls weak security "an industry-wide problem." Jordan explains in the video how he "very easily found the administration interfaces for dozens of Flock safety cameras..." — but also what happened next: None of the data or video footage was encrypted. There was no username or password required. These were all completely public-facing, for the world to see.... Making any modification to the cameras is illegal, so I didn't do this. But I had the ability to delete any of the video footage or evidence by simply pressing a button. I could see the paths where all of the evidence files were located on the file system...

During and after the process of conducting that research and making that video, I was visited by the police and had what I believed to be private investigators outside my home photographing me and my property and bothering my neighbors. John Gaines or GainSec, the brains behind most of this research, lost employment within 48 hours of the video being released. And the sad reality is that I don't view these things as consequences or punishment for researching security vulnerabilities. I view these as consequences and punishment for doing it ethically and transparently.

I've been contacted by people on or communicating with civic councils who found my videos concerning, and they shared Flock Safety's response with me. The company claimed that the devices in my video did not reflect the security standards of the ones being publicly deployed. The CEO even posted on LinkedIn and boasted about Flock Safety's security policies. So, I formally and publicly offered to personally fund security research into Flock Safety's deployed ecosystem. But the law prevents me from touching their live devices. So, all I needed was their permission so I wouldn't get arrested. And I was even willing to let them supervise this research.

I got no response.

So instead, he read Flock's official response to a security/surveillance industry research group — while standing in front of one of their security cameras, streaming his reading to the public internet.

"Might as well. It's my tax dollars that paid for it."

" 'Flock is committed to continuously improving security...'"

T2/Linux Brings a Flagship KDE Plasma Linux Desktop to RISC-V and ARM64 (t2linux.com) 25

T2 SDE "is not just a regular Linux distribution," explains its repository on GitHub. "It is a flexible Open Source System Development Environment or Distribution Build Kit. Others might even name it Meta Distribution. T2 allows the creation of custom distributions with state of the art technology, up-to-date packages and integrated support for cross compilation."

And now after "a decade of deep focus on embedded and server systems," T2 SDE Linux "is back to the Desktop," according to its web site, calling the new "T2 Desktop" flavour "ready for everyday home and office use!" Built on the latest KDE Plasma, systemd, and Wayland, the new T2 Desktop flavour delivers a modern, clean, and performant experience while retaining the project's trademark portability and reproducible cross-compilation across architectures.
T2 Desktop targets x86_64, arm64, and riscv64, delivering "a fully polished, streamlined out-of-the-box experience," according to project lead René Rebe (also long-time Slashdot reader ReneR): I>[T2 Desktop] delivered a full KDE Plasma desktop on RISC-V, reproducibly cross-compiled from source using T2 SDE Linux. The desktop spans more than 600 packages — from toolchain to Qt and KDE and targets a next-generation RVA23 RISC-V flagship desktop, including full multimedia support and AMD RDNA GPU acceleration under Wayland.

As a parallel milestone, the same fully reproducible desktop stack is now also landing on Qualcomm X1 ARM64 platforms, highlighting T2 SDE's architecture-independent approach and positioning both RISC-V and ARM64 as serious, first-class Linux desktop contenders.

Cloudflare Acquires Team Behind Open Source Framework Astro (thenewstack.io) 9

Cloudflare has acquired the core team behind the open source JavaScript framework Astro, bringing its creators in-house while pledging to keep Astro fully open source. The New Stack reports: Astro is used by major brands like IKEA, Unilever, Visa and OpenAI to build fast, content-driven websites. Search engines prioritize fast-loading and clean pages, the Cloudflare statement noted. Websites that rely heavily on JavaScript for initial rendering often struggle to deliver the required speed, which hinders search rankings and customer conversions.

Pages on Astro serve up only the code needed to display a page in a browser. That's in part because of its Island architecture, which it introduced in 2021. Astro's Islands allow developers to create "islands" of interactive client-side components, while most of the page is generated statically in HTML. Server Islands extend the same architecture to the server.

Astro is also UI-agnostic, meaning that while it has its own independent engine, it allows developers to bring in components from React, Svelte, Vue and other frameworks. This makes Astro a preferred choice for building high-performance, content-driven websites optimized for speed, according to Cloudflare.
"Over the past few years, we've seen an incredibly diverse range of developers and companies use Astro to build for the web," said Astro's former CTO, Fred Schott, in a post with Cloudflare senior product manager Brendan Irvine-Broque. "At Cloudflare, we use Astro, too -- for our developer docs, website, landing pages and more." They said that the acquisition will allow them to "double down" on making Astro the best framework for content-driven websites.

Seattle is Building Light Rail Like It's 1999 (msn.com) 99

Seattle was late to the light rail party -- the city rejected transit ballot measures in 1968 and 1971, missing out on federal funding that built Atlanta's MARTA, and didn't approve a plan including rail until 1996 -- but the Pacific Northwest city is now in the middle of a multibillion-dollar building boom that has produced the highest post-pandemic ridership recovery of any US light rail system.

The Link system opened its first line in 2009, funded largely by voter-approved tax measures from 2008 and 2016. The north-south 1 Line now stretches 41 miles after a $3 billion extension to Lynnwood opened in June 2025 and a $2.5 billion leg to Federal Way debuted in December. Ridership is up 24% since 2019, and 3.4 million people rode Link trains in October 2025.

Test trains have been running since September across the I-90 floating bridge over Lake Washington -- what Sound Transit claims is the world's first light rail on a floating structure -- preparing for a May 31 opening. The Crosslake Connection is part of the 2 Line, a 14-mile, $3.7 billion extension voters approved in 2008 that was originally slated to open in 2020. The expansion hasn't come without problems. Sound Transit faces a roughly $30 billion budget shortfall, and a planned Ballard extension has ballooned to $22 billion, double original estimates.

AI Models Are Starting To Crack High-Level Math Problems (techcrunch.com) 113

An anonymous reader quotes a report from TechCrunch: Over the weekend, Neel Somani, who is a software engineer, former quant researcher, and a startup founder, was testing the math skills of OpenAI's new model when he made an unexpected discovery. After pasting the problem into ChatGPT and letting it think for 15 minutes, he came back to a full solution. He evaluated the proof and formalized it with a tool called Harmonic -- but it all checked out. "I was curious to establish a baseline for when LLMs are effectively able to solve open math problems compared to where they struggle," Somani said. The surprise was that, using the latest model, the frontier started to push forward a bit.

ChatGPT's chain of thought is even more impressive, rattling off mathematical axioms like Legendre's formula, Bertrand's postulate, and the Star of David theorum. Eventually, the model found a Math Overflow post from 2013, where Harvard mathematician Noam Elkies had given an elegant solution to a similar problem. But ChatGPT's final proof differed from Elkies' work in important ways, and gave a more complete solution to a version of the problem posed by legendary mathematician Paul Erdos, whose vast collection of unsolved problems has become a proving ground for AI.

For anyone skeptical of machine intelligence, it's a surprising result -- and it's not the only one. AI tools have become ubiquitous in mathematics, from formalization-oriented LLMs like Harmonic's Aristotle to literature review tools like OpenAI's deep research. But since the release of GPT 5.2 -- which Somani describes as "anecdotally more skilled at mathematical reasoning than previous iterations" -- the sheer volume of solved problems has become difficult to ignore, raising new questions about large language models' ability to push the frontiers of human knowledge.
Somani examined the online archive of more than 1,000 Erdos conjectures. Since Christmas, 15 Erdos problems have shifted from "open" to "solved," with 11 solutions explicitly crediting AI involvement.

On GitHub, mathematician Terence Tao identifies eight Erdos problems where AI made meaningful autonomous progress and six more where it advanced work by finding and extending prior research, noting on Mastodon that AI's scalability makes it well suited to tackling the long tail of obscure, often straightforward Erdos problems.

Progress is also being accelerated by a push toward formalization, supported by tools like the open-source "proof assistant" Lean and newer AI systems such as Harmonic's Aristotle.

Cerebras Scores OpenAI Deal Worth Over $10 Billion 15

Cerebras Systems landed a more than $10 billion deal to supply up to 750 megawatts of compute to OpenAI through 2028, according to a blog post by OpenAI. CNBC reports: The deal will help diversify Cerebras away from the United Arab Emirates' G42, which accounted for 87% of revenue in the first half of 2024. "The way you have three very large customers is start with one very large customer, and you keep them happy, and then you win the second one," Cerebras' co-founder and CEO Andrew Feldman told CNBC in an interview.

Cerebras has built a large processor that can train and run generative artificial intelligence models. [...] "Cerebras adds a dedicated low-latency inference solution to our platform," Sachin Katti, who works on compute infrastructure at OpenAI, wrote in the blog. "That means faster responses, more natural interactions, and a stronger foundation to scale real-time AI to many more people."

The deal comes months after OpenAI worked with Cerebras to ensure that its gpt-oss open-weight models would work smoothly on Cerebras silicon, alongside chips from Nvidia and Advanced Micro Devices. OpenAI's gpt-oss collaboration led to technical conversations with Cerebras, and the two companies signed a term sheet just before Thanksgiving, Feldman said in an interview with CNBC.
The report notes that this deal helps strengthen Cerebras' IPO prospects. The $10+ billion OpenAI deal materially improves revenue visibility, customer diversification, and strategic credibility, addressing key concerns from its withdrawn filing and setting the stage for a more compelling refile with updated financials and narrative.
