  • Cloudflare Tries to Outplay Jev With Open-Weight Clef Models
    by BeauHD on 01/10/2026 at 10:00 pm

    Cloudflare has launched two open-weight decision models, Clef and Clef-flash, designed for structured yes/no, multiple-choice, and ranking tasks while also supporting images, video, and up to a 64K context window. Cloudflare says its models outperform TypeSafe's Jev on several benchmarks and can run locally from Hugging Face. The Register reports: For starters, Clef has an LLM backbone. According to Cloudflare, Clef uses specially post-trained, frozen versions of Qwen3.8-27B and Qwen3.5-9B for Clef and Clef-flash, respectively, with the Qwen backbone performing a prefill-only pass during inference. Clef is still fast - faster than Jev, to be fair - and scores choices in parallel after that prefill-only pass. It's not clear what Jev's underlying architecture is, as TypeSafe has kept that a secret. As for its speed and capability, Clef moves fast. Cloudflare ran it against Jev and some other open decision models using the Jev Decision Index available on Hugging Face, and the company's own ranking suggests Clef is slightly slower than other open models, but more accurate, with Clef-flash just as accurate as most of the others, but far faster. To be fair to the competition, Cloudflare self-reported its own scores against the benchmark, and they have yet to be reproduced for ranking on the official Decision Index. Cloudflare also ran Clef against TypeSafe's own benchmarks, and claimed it beat Jev in three out of four areas, only losing out on agent trace observability. Even if it were a bit slower or less accurate, Clef has another major leg up on Jev: It's not limited to classifying text -- it can also handle images and video. Additionally, Clef supports a 64k context window. Jev can also handle up to 64k tokens across a request, although its state plus longest individual question is limited to 32k.

  • Ryan Roslansky Is Leaving After Nearly 18 Years At LinkedIn and Microsoft
    by BeauHD on 01/10/2026 at 9:00 pm

    Ryan Roslansky is leaving Microsoft and LinkedIn after nearly 18 years, triggering another leadership shuffle across Office and Teams. "Roslansky, who until recently was the CEO of LinkedIn, was promoted to the head of Office last year and then took control of Microsoft Teams earlier this year," notes The Verge. From the report: "Ryan leaves the organization in a strong position," says Microsoft CEO Satya Nadella in an internal memo. "Over the past year, Ryan's team has done critical work bringing together the product, engineering, and design foundations that have made this next phase possible." Roslansky is leaving a week after Microsoft announced its new Copilot, which the company is positioning as "the OS for work." He's also leaving around a month after calling fully AI-generated documents "a doom loop" for workers. "If we're not careful, we'll end up with a very expensive way to avoid writing and reading in an ocean of sameness, genericness," said Roslansky in his LinkedIn post. Microsoft is now moving the teams behind Office and Microsoft Teams over to Charles Lamanna, as part of the Copilot, Agents, and Platform (CAP) organization. [...] Microsoft's chief design officer, Jon Friedman, is also moving to report to Copilot chief Jacob Andreou. Microsoft appointed Dan Shapero as its LinkedIn CEO earlier this year, and he will continue in this role and report directly to Nadella. Read more of this story at Slashdot.

  • Micron Projects Tightening RAM Shortages Through 2028 As It Generates Record Profit
    by BeauHD on 01/10/2026 at 8:00 pm

    Micron says the global RAM and storage shortage will tighten further through 2027 and 2028, with CEO Sanjay Mehrotra saying the company has already sold most of next year's capacity. "In calendar 2027 as well as 2028, we see demand exceeding supply. In fact, we see greater tightness in the industry in 2027 and in 2028 versus 2026. Overall, supply-demand environment is only getting tighter," Mehrotra said. "We do not have line of sight to when supply and demand will return to balance." As a result, the company is forecasting record revenue and an 86.25% gross margin. Tom's Hardware reports: The memory and storage industry is not holding back on increasing production, though, with Micron saying that NAND and DRAM shipments are expected to grow in the low-to-mid 20s percentage range for the next two years. However, it seems that this is not enough to match growing demand, as it expects "the industry to remain supply constrained in both years." Still, it seems that manufacturers are prioritizing HBM demand for AI data centers, with the company expecting shipments of these chips to grow faster than conventional DRAM. Micron and other chip manufacturers are bringing new factories online to increase output, but it's going to take years before they can start producing chips. But even as we're amid an unprecedented multi-year memory chip shortage, Micron also announced record financial guidance. It forecasted a record $61.5 billion FQ1 revenue and a gross margin of 86.25%, implying a gross profit of more than $53 billion. After accounting for an estimated $2.06 billion in operating expenses and a tax rate of around 15.5%, the company said its earnings per share sit at $38.15, plus or minus $1.00, for approximately 1.15 billion shares.

  • Cops Can Bypass iPhone's Automatic Reboot To Get Into Locked Phones
    by BeauHD on 01/10/2026 at 7:00 pm

    An anonymous reader quotes a report from 404 Media: A company that makes phone hacking devices claims to have developed a solution that freezes iPhones in a state that lets cops more easily access sensitive data inside them, according to a video obtained by 404 Media. [...] The new technology to get around inactivity reboot was developed by Magnet Forensics, the company behind GrayKey, a popular tool sold to law enforcement agencies that allows them to unlock and access data stored in iPhones and Android smartphones. Magnet has developed a new device called GrayKey Preserve and a feature for its regular GrayKey devices called Evidence Preservation Mode, according to the video. "This is an absolute game changer for iOS forensics and a function that I wish we had years ago," a Magnet employee says in the leaked video, specifically mentioning that the solution is targeted at the iPhone's inactivity reboot feature and the data it makes unavailable. GrayKey Preserve and Evidence Preservation Mode are also designed to combat another iPhone feature that automatically deletes certain data -- such as cached locations, and recently deleted photos and iMessages -- after a certain number of days. "We're gonna be able to preserve that data for an infinite amount of time." [...] 404 Media shared a transcript of the video with Jiska Classen, a researcher at the Hasso Plattner Institute who studies iPhone security. While Classen said that it's impossible to know for sure how Magnet's new feature works based on the video, she posited some theories and agreed that it is "quite a game changer" or "at least puts things back to where they were before inactivity reboot." She thinks Magnet has found a way to manipulate the iPhone's clock, effectively "slowing down time" or even "stopping the clock from ticking, even after a reboot." Most likely, according to her, the GrayKey may disable the iPhone tasks that set data to expire. The "inactivity reboot" feature mentioned above was added to iOS in November 2024 and automatically restarts iPhones that have not been unlocked for 72 hours, making them harder for police to access using forensic tools.

  • Pentagon Creates 'Autowarcom' to Expand AI and Drone Capabilities
    by BeauHD on 01/10/2026 at 6:00 pm

    Longtime Slashdot reader ThurstonMoore shares a report from Reuters: U.S. Defense Secretary Pete Hegseth on Wednesday announced the creation of a new military command that would be dedicated to building and providing autonomous and robotic capabilities across the U.S. military. The command, which Hegseth said would be called "Autonomous Warfare Command," highlights the rapidly changing nature of warfare and the need to make progress on systems like drones and the use of artificial intelligence. Speaking in front of hundreds of junior officers and enlisted personnel at Quantico, Virginia, in a speech peppered with attacks on the media, Hegseth said the command would be led by a four-star officer. "The pace of war is changing faster than the process to support it," Hegseth said in a speech called the "State of the Force," in which he announced other changes, including the creation of the office of religious affairs. "Cheap compute, superintelligence, and advanced commercial manufacturing have enabled the proliferation of low-cost, high-precision strike," Hegseth added. [...] The United States has long relied on its vast military budget to field some of the world's most expensive weapons systems. But there is an increasing realization within the Pentagon that this is not sustainable. "Today we need both quality and quantity," Hegseth said. Read more of this story at Slashdot.

  • FTC Is Investigating OpenAI, Anthropic and Other AI Companies Over Product Risks
    by BeauHD on 01/10/2026 at 5:22 pm

    The Federal Trade Commission has opened an investigation into OpenAI, Anthropic and other AI companies over potential consumer and safety risks posed by their products, with the agency reportedly preparing requests for documents and executive testimony. CNBC reports: OpenAI stunned the industry in July when it disclosed that its agents broke out of a testing environment and hacked into open-source platform Hugging Face. [...] Earlier this month, Anthropic CEO Dario Amodei rocked the tech sector by urging AI companies to slow how quickly they improve their most advanced models and calling for stronger government oversight. He published a three-step proposal aimed at tempering the pace of development without "sacrificing commercial advantage or the United States' lead in AI." CEO Jensen Huang, argued that individual companies should be responsible for ensuring the safety of their products. President Donald Trump convened top executives from Alphabet, Meta, SpaceX, Nvidia, Palantir, Anthropic, OpenAI and other companies on Tuesday to discuss the issue. The group signed a short voluntary, nonbinding accord, which says that "every company is responsible for developing its own technology safely and in a way that builds trust with customers and the public."
