  • Roku Raises Prices of Streaming Devices By Up To 60%
    by BeauHD on 24/07/2026 at 9:00 pm

    Roku has raised prices on several streaming devices, blaming memory and component shortages tied to the AI data-center boom. The Roku Ultra jumped from $100 to $150 and the basic Streaming Stick rose from $30 to $40. The Desk reports: In a phone call with The Desk on Friday, a Roku executive said the company made the tough decision to raise prices on its streaming hardware to address shortages in computer memory and other components caused by the artificial intelligence rush. [...] Still, the executive who spoke with The Desk on Friday said the company believes its hardware is still competitive against other streaming TV hardware because Roku devices are still priced aggressively compared to the Apple TV and other expensive streaming hardware, and the company remains focused on looking at ways to add value to its Roku platform before and after it enters a customer's home. "We are doing our best to have great deals like what we have going on right now," the executive said. "Roku is even upping the price for a bundle that includes a Streaming Stick Plus and a one-month subscription to Fox One," notes Ars Technica in a separate report. "As recently as July 20, Roku listed the bundle at $60 with a sale price of $25, according to the Internet Archive's Wayback Machine. Now, the bundle carries an $80 MSRP and $45 sale price."

  • Nvidia, Microsoft, Meta Warn Against 'Premature Restrictions' of Open-Weight Models
    by BeauHD on 24/07/2026 at 8:00 pm

    Nvidia, Microsoft, Meta, Palantir, and more than 20 other tech companies signed an open letter urging policymakers not to impose "premature restrictions" on open-weight AI models, warning that broad limits could "stifle competition or drive innovation overseas." CNBC reports: They wrote that open-weight models strengthen competition and ensure that the benefits of the technology are "broadly shared rather than concentrated in a few hands." "Relying solely on closed models is not inherently safe: they can be breached, misused, or fail in ways that outsiders cannot detect," the letter said. "And concentrating advanced AI capabilities behind a small number of closed models compounds that risk." Elon Musk, who runs an AI business under his rocket company SpaceX, also applified the letter on social media, writing that it has his "full support" in a post on X. SpaceX did not officially sign the letter. Greg Brockman, OpenAI's president, said Thursday that the company believes in broad access, and that he has not been involved in any conversations with the Trump administration about potentially banning Chinese open-weight models in the U.S. "I think that, that fundamentally, AI and AI usage is something that is actually very important to democratize," Brockman told reporters during a briefing in New York City. "And so, for me, at a sort of deep level, I think that having more models, more usage, that is a good thing." OpenAI CEO Sam Altman addressed the letter in a post on X on Friday, writing that he wants the U.S. to win with both open-weight and proprietary models, and that he is "glad to see this." [...] In the letter on Friday, the U.S. tech companies said that concerns about unlawful distillation should be addressed through "targeted legal and commercial frameworks" instead of with "sweeping restrictions on techniques that play an important role in AI innovation." "Our AI leadership will be judged not by one frontier AI model, but by whether the United States builds a strong, open ecosystem that diffuses into every sector," the letter said. "This is essential for creating opportunities for innovation and prosperity across the country." The letter follows a separate appeal signed by nearly 200 Silicon Valley companies, including Proton and Y Combinator, warning that restricting U.S. access to Chinese open-weight AI models could cripple the next generation of American startups. "American leadership requires two things: world-leading American open-weight models and continued access for U.S. builders to open models already available worldwide," the startup founders wrote. Instead of broad prohibitions, they argue the government should adopt targeted safeguards. Of course, these signees "have an obvious economic stake in seeing open AI models flourish," notes TechCrunch. "Companies like Nvidia, Microsoft Azure, and other infrastructure providers have a vested interest in pushing for commoditized models: If models are interchangeable, people will buy more GPUs, rent more cloud capacity, and build more applications."

  • Anthropic's New Opus 5 Model Rivals Fable 5 For Half the Price
    by BeauHD on 24/07/2026 at 7:00 pm

    Anthropic has released Opus 5, a new Claude model that it says comes close to its higher-end Fable 5 model at half the price while improving on Opus 4.8 in knowledge work, coding, and scientific research tasks. "At the same time, Anthropic says it has managed to make the model more resistant to being tricked," notes Engadget. Additionally, the company says Opus 5 "exhibits the lowest rates of deceptive behavior." From the report: One important distinction between Opus 5 and Mythos, which is currently only available to a limited number of vetted organizations through Anthropic's Project Glasswing initiative, is that the company has specifically avoided training the new model on cyber-related tasks. Due to more its powerful capabilities, Opus 5 is broadly better at those tasks than its predecessor, making it more useful for finding cybersecurity vulnerabilities, but the company says Opus 5 is "substantially behind" its flagship model at exploiting those vulnerabilities. [...] Anthropic says "Claude Opus 5's safeguards are designed to allow beneficial uses of the model in both cybersecurity and biology." The company has strengthened some of the model's cyber-related guardrails, but notes it did so along a "narrow range" of specific tasks. "Based on our testing, we expect the classifiers to intervene around 85 percent less often than they do for Fable 5," Anthropic said. With Opus 5, Anthropic also isn't including it in its recently announced 30-day data retention policy, which the company introduced alongside Fable and Mythos 5. As for pricing. Anthropic says API costs for Opus 5 will remain at $5 per one million input tokens and $25 per one million output tokens. Anthropic has also added an "effort" menu for Opus that users can tweak to tell the model whether they want it to be more thorough or fast and efficient to conserve tokens.

  • John C. Dvorak, an Early and Influential Technology Journalist, Dies At 80
    by BeauHD on 24/07/2026 at 5:00 pm

    Longtime Slashdot reader sandbagger shares the passing of John C. Dvorak, an early and influential technology journalist for PC Magazine. He was 80. Talking Biz News reports: Aric Mackey writes, "Widely recognized for his profound impact on the technology industry, John's career spanned decades of rapid digital evolution. He was perhaps best known for his influential, long-running column in PC Magazine and his groundbreaking work on the No Agenda podcast. Through his prolific writing, broadcasting, and distinct public voice, he helped shape critical conversations around both technology and political analysis, guiding generations of readers and listeners with his unique perspective. "To those who knew him personally, John was far more than his public work. He was a beloved husband, devoted father, proud grandfather, and a loyal friend. Those closest to him will remember a man defined by his strong convictions, his exceptionally sharp wit, and an enduring curiosity about the world around him." Dvorak was also part of the startup team at CNET Networks, and appeared on MarketWatch TV. Read more of this story at Slashdot.

  • Stripe Eyes $10 Billion Deal For AI Model Marketplace OpenRouter
    by BeauHD on 24/07/2026 at 4:00 pm

    An anonymous reader quotes a report from PYMNTS.com: Stripe is in talks to buy OpenRouter, an artificial intelligence (AI) startup that could sell for roughly $10 billion, according to The Wall Street Journal. The move would mark a significant step outside payments for a company that processes transactions for much of the internet. It also lands while Stripe pursues a far larger target: a bid for PayPal that would value the payments giant at about $53 billion. The Journal reported Thursday (July 23) that a transaction could be announced soon, though the talks could still collapse or another buyer could step in. The exact price under discussion could not be learned. Several other large technology companies had also been weighing deals for OpenRouter. The startup was valued at $1.3 billion in May, according to PitchBook, meaning a sale near $10 billion would represent a steep markup in a matter of months. Its backers include Menlo Ventures and CapitalG, the growth fund of Google parent Alphabet. OpenRouter sells software that lets customers reach AI models from OpenAI and Anthropic, along with open weight alternatives anyone can download and run. The Journal described the company's position this way: "OpenRouter is part of an emerging crop of startups that have found a lucrative niche between AI developers and the companies that want to use them." The platform lists hundreds of large language models and lets developers compare and switch between them. Read more of this story at Slashdot.

  • Astronomers May Have Discovered First Moon Outside Our Solar System
    by BeauHD on 24/07/2026 at 3:00 pm

    Astronomers studying the star system CD-35 2722 may have found the first known moon-like object outside our solar system. The classification is unusually tricky, however, because it orbits a brown dwarf rather than a planet, making it clearly an "exosatellite" but forcing scientists to rethink where the line between planet, moon, and failed star should be drawn. Space.com reports: The star CD-35 2722 is located around 73 light-years away and has around half the mass of the sun. It is orbited by a "failed star" or brown dwarf. These stellar bodies get their unfortunate nickname because they form like other stars but fail to gather enough mass to trigger the fusion of hydrogen to helium in their cores. In terms of mass, brown dwarfs are more massive than the largest gas giant planets, but smaller than the smallest stars, usually with around 13 to 80 times the mass of Jupiter, or around 0.013 to 0.08 times the mass of the sun. The newly discovered object in CD-35 2722 is certainly moon-like, but rather than orbiting a planet as the moons in the solar system do, it orbits the system's brown dwarf. "This system is somewhat hard to define using solar-system-based words like 'planet' and 'moon.' The exosatellite is clearly massive enough to be a planet, but it does not orbit a star, though it orbits an object that orbits a star," team leader Kevin Hoy of the Universidad Diego Portales and the Millennium Nucleus of Young Exoplanets and their Moons (YEMS) in Chile, said in a statement. "Being the third wheel in this system makes us want to call it a moon, even if it is nothing like the small, rocky moons we have in our system." The team currently isn't able to definitively claim this object in CD-35 2722 is an exomoon, because that would require really nailing down a new definition of what a moon is. "The satellite we report is a giant gaseous body orbiting a highly massive companion, itself several times the mass of Jupiter. We have a clear delineation between the planets and the sun in the solar system, so defining things like moons is simple," team member Alice Zurlo of the Universidad Diego Portales said. "In the CD-35 2722 system, where we are blurring the lines between stars, planets, and moons, the whole thing becomes more complicated to describe." Zurlo and colleagues can, however, confidently claim this is an exosatellite, meaning it is a first-of-its-kind detection no matter what the future holds for its classification. The findings have been published in the journal Nature. Read more of this story at Slashdot.
