  • Smartwatch pioneer and Kickstarter darling Pebble is returning in a new form
    techcrunch.com
    Four years after launching the (then) most lucrative crowdfunding campaign in Kickstarters history, Pebble abruptly ended. The hardware startup closed 2016 by filing for insolvency, before being sold off to Fitbit. The fitness-tracking giant built much of the Ionic smartwatch with help from former Pebblers, along with the companys pioneering software stack.The first Apple Watch launched in mid-2015, proceeding to suck much of the oxygen out of the room. It would, however, be massively oversimplifying the situation to suggest that it was merely another case of Sherlocking. Apple, after all, raised public interest, ultimately setting the stage for countless other smartwatches after.It could be argued that Pebble was cursed with foresight and was simply too early to the space. Founder and CEO Eric Migicovsky would argue that the companys rapid growth and feature expansion caused Pebble to lose sight of his initial vision. It certainly wouldnt be the first time a hardware startup was felled by such fate.Eight years after selling the company off to Fitbit, Migicovsky is ready for round two. Were restarting Pebble, he told TechCrunch with a massive grin on a Zoom call Monday. That, too, however, is an oversimplification. After all, five years after buying the startup, Fitbit was sold off to Google. While Pebble branding ultimately faded as the company was absorbed the first time, the software giant still owns the technology and all of its IP.Still in the idea stage, Migicovskys planned company needs a new name something the Beeper co-founder and former Y-Combinator partner hasnt quite gotten around to. His decision to announce a Pebble 2.0 in its infancy is the product of a massively consequential decision announced by Google on Monday.Image Credits:TechCrunchWhile it apparently has no plans to surrender Pebble as a brand, Google is returning its roots by open-sourcing the smartwatch brands software stack. While former Pebble employees have remained onboard at Google as the company has poured more resources into its own smartwatch operating system, WearOS, its not clear how much if any of Pebbles technology exists in products like the Pixel Watch.This is part of an effort from Google to help and support the volunteers who have come together to maintain functionality for Pebble watches after the original company ceased operations in 2016, Google writes in a blog post.By open-sourcing access to PebbleOS Google is opening the door to new third-party hardware. Migicovskys unnamed smartwatch startup is first on that list. The founder tells TechCrunch that hes thrown himself into the project full time and will be able to accelerate things as access to PebbleOS opens up. He is, however, currently its only employee, though there are plans to bring on another around March.The startups goals are fittingly humble. Migicovsky says he simply wants to make the watch he wants, given that the Pebble he wears to this day is now a decade old. Ive tried everything else, he says. I have very high standards.Those are, according to a new blog post on Migicovskys personal site:Always-on e-paper screen (its reflective rather than emissive. Sunlight readable. Glanceable. Not distracting to others like a bright wrist)Long battery life (one less thing to charge. Its annoying to need extra cables when traveling)Simple and beautiful user experience around a core set of features I use regularly (telling time, notifications, music control, alarms, weather, calendar, sleep/step tracking)Buttons! (to play/pause/skip music on my phone without looking at the screen)Hackable (apparently you cant even write your own watch faces for Apple Watch? That is wild. There were >16k watch faces on the Pebble app store!)During its relatively brief life, Pebble sold 2 million smartwatches. Its an impressive feat in the world of hardware startups, but ultimately not enough to maintain the required momentum.In spite of his time at YC, Migicovsky has no plan to raise VC funds. Nor does he plan to return to the Kickstarter model that gave rise to Pebble the first time around. He is currently self-funding the project and says he plans to build it modestly, based on consumer interest.As for whether an audience remains for Pebble in a post-Apple Watch world, he jokes, There are at least dozens of us. He notes that the brand still commands its own active Subreddit, eight years after closing its doors. A small resale market has propped up around older devices, though as anyone who has bought a piece of consumer electronics in the past two decades can tell you, hardware doesnt last forever.Migicovsky is planning the company to serve the specific needs of those who want precisely what he laid out in his blog post. Its difficult to say how many people yearn for the discontinued product in a world where Apple has dramatically shifted user expectations, but hes betting on not being alone in his desires.This is a passion project. I have a vested interest in making the watch, Migicovsky says of building a startup to create a product he wants to wear. Were going to make this happen.Despite being in its infancy, Migicovsky has visited Shenzhen in a bid to scope out the current state of manufacturing. Turns out making hardware is much easier than it was 10 years ago, he says. There were no smartwatches factories. We had to tell the factories what to do.He also says that he feels confident about the small startups ability to build a new Pebble for the current era. The hard part is the software.By opening up PebbleOS, Google made that bit considerably easier.

  • DeepSeek displaces ChatGPT as the App Stores top app
    techcrunch.com
    The mobile app for DeepSeek, a Chinese AI lab, skyrocketed to the number-one spot in app stores around the globe this weekend, topping the U.S.-based AI chatbot, ChatGPT. On iOS, DeepSeek is currently the No. 1 free app in the U.S. App Store and 51 other countries, according to mobile app analytics firm Appfigures.The rapid rise of DeepSeek in the app stores Top Charts follows its meteoric rise in popularity this week resulting from the release of a series of open AI models that are competitive with leading offerings from OpenAI and Google. However, compared to other frontier AI models, DeepSeek claims its models were trained for just a fraction of the price with significantly worse AI chips. This represents new efficiency gains for AI model training, which sent Nvidias stock price tumbling down as much as 17% on Monday, and has put the rest of the tech industry on high alert.On Friday, DeepSeeks mobile app had just a million downloads across both the App Store and Google Play. That number has since doubled, as of Monday morning, to 2.6 million downloads of DeepSeeks mobile app across both platforms. The app currently sits in the Top 10 list for free apps in 111 countries on the App Store, and 18 countries on Google Play, according to Appfigures.In addition, more than 80% of DeepSeeks total mobile app downloads have come in the past 7 days, according to analytics firm Sensor Tower. In that time frame, DeepSeek saw nearly 300% more app downloads than Perplexity, another leading consumer AI app.DeepSeek moved into its No. 1 spot on the U.S. App Store on Sunday, Jan. 26, up from No. 31 just a couple of days prior. Meanwhile, DeepSeek is the No. 14 Overall free app on Google Play, rapidly climbing up from No. 133 on Jan. 24. As a result, daily active users jumped both globally and in the U.S. by over 110% from Jan.24-25 compared with the same period last week. While China is the largest mobile app market for DeepSeek today, it only represents 23% of its total downloads, according to Sensor Tower. The apps second and third largest markets are the United States, which makes up 15% of its total downloads, and Egypt, which makes up 6% of its total downloads.The popularity of DeepSeeks mobile app raises questions about the moat of popular consumer AI apps, such as ChatGPT, Gemini, and Perplexity. While hundreds of millions of people use ChatGPT and Gemini every month, DeepSeek proves that the consumer AI space is still volatile, and new competitors shouldnt be counted out.However, its worth noting that reaching the No. 1 position on the App Store isnt just calculated by app downloads alone. Apples algorithm, though secretive, is a combination of numerous factors including also velocity of the installs and more. That allows apps that gain installs quickly to skyrocket to the top of the charts, overtaking others that may have a larger total number of users or installs. It will be more telling to see how long DeepSeek holds its top position over time. The tech industry is still coming to terms with the techniques DeepSeek used to train its AI models, and what it means for the broader AI space. In light of DeepSeeks R1 model, leading AI model providers may be feeling pressured to release better models to prove their dominance, or justify the hefty price theyre paying for compute. Meta has reportedly created several war rooms to analyze DeepSeeks training methods.DeepSeeks rise in popularity was potentially stifled by large-scale malicious attacks, the company reported on Monday, which forced it to limit customers outside of China from registering for the app. Additional reporting: Sarah Perez

  • I've tried many smart locks, but the one I keep on my door is 35% off
    www.zdnet.com
    Maria Diaz/ZDNETWhat's the deal?The Aqara U100 smart lock is $80 off, available for one the lowest prices we've ever seen at $150 with a limited-time deal.ZDNET's key takeawaysThe Aqara U100 smart lockwas originally priced at $230, but it is currently discounted to $150.This smart lock is the most versatile I've tested. It offers a variety of unlocking options, a user-friendly app, and easy integration with Apple Home.The Aqara U100 drains the battery quickly, and the app doesn't always alert users, resulting in reduced performance within four months of use.Aqara launched its first Apple Home Key smart lock in the US after selling many Home Key-compatible smart locks outside the country. Was the wait worth it? I've had the Aqara U100 for over a year, and the short answer is: Absolutely.Getting the Aqara U100 on my front door was reasonably simple, even though my specific review unit didn't come with instructions. It took a few minutes to figure out which piece goes on before the other, but a deadbolt is a pretty straightforward mechanism, so it was easy. The entire process took less than 15 minutes.Once the U100 smart lock was on the door, I set it up with the Aqara app on my iPhone and used an Aqara M2 Hub to connect to it. details View at Amazon Although an Aqara Hub isn't necessary to use the basic features of the smart lock, you do need one to perform remote lock and unlock actions, view the current lock status, configure password settings from your phone, and create automations with other Aqara devices. I used the Aqara Hub M2 to set up the U100 lock. Maria Diaz/ZDNETWithout a hub, the U100 smart lock can only connect to your phone via Bluetooth and be controlled as long as you're within Bluetooth range. The lock blends seamlessly alongside my door. Maria Diaz/ZDNETThe Aqara U100 smart lock is unique in the US, as it's the only one on the market to offer the following unlocking options in one:Passcode unlock: The U100 lock features a keypad that requires 6-10 digit passcodes to open. You can add one-time passcodes or ones that only work during a preset period, like for a babysitter every weekday from 3-6 p.m. The app allows you to set up to 75 passwords.Fingerprint unlock: After setting up my U100 to open with my fingerprint, I've never had issues with it not recognizing my print or failing to respond to it. You can add up to 50 fingerprints in the app, and Aqara says its fingerprint reader features a 98.6% recognition rate.Apple Home Key: I set up the U100 lock to unlock with my iPhone using the NFC-powered Apple Home Key. This adds a virtual key to your iPhone's Wallet, and you can open your smart lock only by bringing your iPhone or Apple Watch close to it.NFC tags: You can also program NFC tags to unlock the Aqara U100, which is perfect for anyone who isn't an Apple user, or to use as keycards for houseguests.Mechanical keys: The U100 smart lock comes with two physical keys, and the keyhole is hidden behind a sliding panel on the face of the wave.Although I didn't find the Aqara mobile app very intuitive, I loved the features available for the U100 lock. You can add other users and give them each a unique unlocking method. For example, I've always given myself a passcode and a fingerprint to track who entered and how when checking the lock's event history. Maria Diaz/ZDNETThe app also lets you customize alert settings and choose the voice volume and language for any voice alerts during the locking operation. Thanks to a built-in gyroscope for motion detection, you can set the device to auto-lock when the door is closed (no extra modules are required).That said, it wasn't all sunshine and automatically locked doors. I sometimes struggled with the app's beta features, especially when it came time to get the U100 to lock behind me or when I swiped it. At one point, I had to go back inside to find the mechanical key because it wasn't working. I later realized this happens when the lock's battery life ends after three to four months.While my experience was mostly positive, I found the app very slow and unreliable at giving me the lock status, even when my phone was within Bluetooth range. Sometimes, it would just give me the wrong status and say the door was locked when I could see clearly that it wasn't, but this was resolved after a few months and some updates.ZDNET's buying advice The Aqara U100 smart lock has a hidden keyhole. Maria Diaz/ZDNETWhy do I still love the Aqara U100? The pros outweigh the cons, and the firmware upgrades keep improving performance.Considering how elaborate smart locks can get, I went into this review biased toward the simplicity of the Level Lock+and the sleek design of the Yale Assure Lock SL. The additional unlocking features that make the Aqara U100 unique turned me around.Being able to consistently (and flexibly) unlock my door with either my fingerprint or Apple Watch, and not one or the other, has added the exact amount of convenience to my life that I look for in all smart home devices. When will this deal expire? While many sales events feature deals for a specific length of time, deals are on a limited-time basis, making them subject to expire anytime.

    www.forbes.com
    Apple's iOS 18.3 fixes a hefty list of 29 vulnerabilities, one of which has already been used in ... [+] attacks.Apple iPhoneApple has issued iOS 18.3, along with a warning to update your iPhone now. Thats because iOS 18.3 fixes a hefty list of 29 vulnerabilities, one of which has already been used in attacks.Apple doesnt give much detail about the issues fixed in iOS 18.3, because it wants to give people as much time to update as possible before attackers can get hold of the details.But the already exploited issue patched in iOS 18.3 is a flaw in CoreMedia tracked as CVE-2025-24085 that could see a malicious application able to elevate privileges.Apple is aware of a report that this issue may have been actively exploited against versions of iOS before iOS 17.2, the iPhone maker said on its support page.Whats Fixed In iOS 18.3Apples iOS 18.3 also fixes two bugs in the Kernel at the heart of the iOS operating system. Tracked as CVE-2025-24107, the first flaw could see a malicious app able to gain root privileges. Meanwhile, the second issue could allow an app to execute code with Kernel privileges.MORE FOR YOUThe iOS 18.3 update patches several flaws in WebKit, the engine that underpins the Safari browser. A bug in WebKit Web Inspector could lead to command injection where a malicious hacker tricks an application into executing operating system commands.Meanwhile, an issue in AirPlay tracked as CVE-2025-24137 could allow a remote attacker to cause an unexpected application termination or code execution.Another bug in Passkeys could see an adversary use an app to gain unauthorized access to Bluetooth.Why You Should Update To iOS 18.3 NowApple released iOS 18.3 alongside iPadOS 17.7.4, but there is no iOS 17.7.4 update yet. This could be because iOS 17 is not affected, or because Apple is no longer offering the update to newer devices, or the details arent available yet.But at least for now, the lack of available iOS 17 updates means you will be more secure if you update to iOS 18.When you do upgrade to iOS 18.3, note that Apple has automatically enabled AI for iPhone 15s and above, so check your settings and disable if you want.Apples iOS 18.3 is available for the iPhone XS and later, iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later and iPad mini 5th generation and later.In my mind, upgrading to iOS 18.3 is a no-brainer.

  • The Role Of Telehealth And Technology In Providing Autism Care
    www.forbes.com
    Telehealth and advanced technologies are emerging as vital tools in meeting this demand. From ... [+] addressing delays in diagnoses to improving access to personalized care, these innovations are helping bridge critical gaps in autism services.gettyThe prevalence of autism has surged dramatically in recent years. Globally, cases increased from 28.3 million in 2019 to 61.8 million in 2021a staggering 118% rise in just two years. In the U.S., where 1 in 36 children now receives an autism diagnosis, healthcare systems face mounting pressure to provide timely and effective care.Telehealth and advanced technologies are emerging as vital tools in meeting this demand. From addressing delays in diagnoses to improving access to personalized care, these innovations are helping bridge critical gaps in autism services.The Crisis of Delayed DiagnosesWait times for autism care are a huge issue in many parts of the country, explains Dr. Doreen Samelson, Chief Clinical Officer at Catalight. First, people go on a waiting list for a diagnosis. Then they wait again for treatment. In some cases, it can be years between their initial concern and the start of treatment.This delay can be devastating, particularly given the importance of early intervention. Autisms variability only compounds the challenge. From individuals with mild autism who are highly independent to those requiring lifelong support, the spectrums breadth makes timely and accurate diagnosis difficult.Adding to the complexity, behaviors associated with autism often overlap with co-occurring conditions such as ADHD, gastrointestinal issues, and psychiatric disorders. These layers of complexity make it crucial to move beyond surface-level assessments.MORE FOR YOUTelehealth as a Game-ChangerDoctor talking to a young patient at home through a video call - telemedicine conceptsgettyTelehealth is uniquely positioned to address the challenges of delayed diagnoses and fragmented care. By enabling clinicians to observe children in their home environments, telehealth eliminates the stress of traveling to unfamiliar settings while offering a clearer picture of daily life.For families in rural areas or those who face transportation challenges, telehealth can be essential for accessing care, says Samelson. It allows clinicians to understand patients in context, leading to more accurate diagnoses and personalized care plans.Telehealth also enhances emotional comfort, particularly for children with sensory sensitivities or social anxiety. By conducting sessions in familiar environments, clinicians can foster a sense of security that encourages engagement and cooperation.Bridging the Knowledge Gap with AIAnother promising innovation lies in artificial intelligence (AI), which has the potential to transform how clinicians and caregivers approach autism care.Existing generative AI and automation capabilities have incredible near-term potential to close the knowledge gap between patients and doctors, explains Keri Schoenbrun, Development Director at TLI.The challenge is vast. A recent study found over 57,000 research articles on autism were published between 2011 and 2022a 160% increase. For doctors juggling diverse patient populations, keeping up with this rapidly expanding body of knowledge is nearly impossible. AI offers a solution by sifting through data and connecting the dots across complex diagnostic profiles.Schoenbrun shares a compelling example: Imagine a child experiencing a spike in aggressive behavior at school and recent blood work showing low cholesterol levels. The link between these factors might be overlooked, but AI can bring existing research to the forefront, ensuring conditions like this arent missed.This capability extends beyond diagnosis. AI can also help clinicians identify and treat co-occurring conditions, enabling a more comprehensive approach to health.Supporting Clinicians and CaregiversBeyond its diagnostic capabilities, AI is revolutionizing the day-to-day work of clinicians. Tools ... [+] like ambient notetaking technology allow healthcare providers to focus more on patients and less on administrative tasks.gettyBeyond its diagnostic capabilities, AI is revolutionizing the day-to-day work of clinicians. Tools like ambient notetaking technology allow healthcare providers to focus more on patients and less on administrative tasks.No one goes into this field to take notes, says Samelson. Using AI to complete these tasks more efficiently allows clinicians to see more patients and increase access to care.This technology is also beneficial for neurodivergent clinicians themselves. Samelson notes that ambient AI tools make it easier for individuals with dyslexia or ADHD to thrive in their roles, promoting diversity and inclusion within the healthcare workforce.Caregivers, often the backbone of support for neurodivergent individuals, also benefit from these advancements. AI-powered platforms streamline care coordination and provide personalized support, easing the burden on families.Many caregivers, myself included, quit their jobs to manage the overwhelming coordination required to access quality healthcare, shares Schoenbrun. AI can reduce this load, enabling families to focus on what matters most: their loved ones well-being.Addressing Communication BarriersFor many autistic individuals, communication barriers can hinder effective healthcare delivery. These challenges often result in missed diagnoses or inappropriate treatment plans.It may be necessary to rethink the typical office visit to ensure patients and caregivers can use the communication techniques that work best for them, says Schoenbrun.Emerging technologies are helping bridge these gaps. Tools like eye tracking and emotional feedback systems can offer valuable insights into nonverbal cues, aiding clinicians in better understanding their patients. Wearable devices that monitor anxiety levels and suggest calming interventions also hold promise for improving emotional regulation.Wearable technology that senses rising anxiety and nudges individualsor their caregiversto engage in soothing activities could significantly reduce dangerous behaviors and improve overall well-being, says Samelson.Comprehensive Care: A Holistic ApproachAs the healthcare system evolves, theres a growing recognition of the need for holistic approaches that prioritize overall health alongside behavioral interventions.While ABA is one of the most common evidence-based interventions for autism, a person needs to be healthy and comfortable in their own skin to make progress in therapy, says Schoenbrun.This requires addressing co-occurring conditions that may impact quality of life. Unfortunately, these conditions are often overlooked in the rush to begin behavioral treatments. Connecting patients and physicians to peer-reviewed research on managing these conditions can significantly improve outcomes.The Future of Autism CareFor these advancements to succeed, inclusivity must remain at the heart of innovation. gettyThe integration of technology into autism care is still in its early stages, but its potential is transformative. Telehealth, AI, and wearable devices are not just toolstheyre the foundation of a more inclusive, responsive, and effective healthcare system.Schoenbrun envisions a future where AI enables a new standard of care for autistic individuals. As doctors gain access to better information, well see the emergence of autism specialists who take a more informed and nuanced approach to treating patients, she says.This shift will benefit not just autistic individuals but the entire healthcare system. Technology can improve care across the board, says Samelson. From reducing wait times to enhancing diagnostic accuracy, its impact is far-reaching.Building Inclusive SystemsFor these advancements to succeed, inclusivity must remain at the heart of innovation. By involving neurodivergent individuals and their families in the development of new tools, healthcare systems can ensure that solutions are ethical, effective, and equitable.The big innovation is applying AI to solve problems at the intersection of individualized diagnostic profiles and a growing body of research, says Schoenbrun. Its about creating tools that work for everyone, not just the majority.As the healthcare landscape continues to evolve, the goal is clear: to create a system that meets the needs of all individuals, regardless of their unique challenges.

  • What to Know About DeepSeek, the Chinese AI Company Causing Stock Market Chaos
    time.com
    By Billy Perrigo and Tharin PillayJanuary 27, 2025 1:55 PM ESTA new Chinese AI model, created by the Hangzhou-based startup DeepSeek, has stunned the American AI industry by outperforming some of OpenAIs leading models, displacing ChatGPT at the top of the iOS app store, and usurping Meta as the leading purveyor of so-called open source AI tools. All of which has raised a critical question: despite American sanctions on Beijings ability to access advanced semiconductors, is China catching up with the U.S. in the global AI race? At a supposed cost of just $6 million to train, DeepSeeks new R1 model, released last week, was able to match the performance on several math and reasoning metrics by OpenAIs o1 model the outcome of tens of billions of dollars in investment by OpenAI and its patron Microsoft. The Chinese model is also cheaper for users. Access to its most powerful versions costs some 95% less than OpenAI and its competitors. The upshot: the U.S. tech industry is suddenly faced with a potentially cheaper and more powerful challenger, unnerving investors, who sold off American tech stocks on Monday morning. Yet not everyone is convinced. Some American AI researchers have cast doubt on DeepSeeks claims about how much it spent, and how many advanced chips it deployed to create its model.Few, however, dispute DeepSeeks stunning capabilities. Deepseek R1 is AI's Sputnik moment, wrote prominent American venture capitalist Marc Andreessen on X, referring to the moment in the Cold War when the Soviet Union managed to put a satellite in orbit ahead of the United States.So, what is DeepSeek and what could it mean for U.S. tech supremacy? What is DeepSeek?DeepSeek was founded less than two years ago by the Chinese hedge fund High Flyer as a research lab dedicated to pursuing Artificial General Intelligence, or AGI. A spate of open source releases in late 2024 put the startup on the map, including the large language model v3, which outperformed all of Meta's open-source LLMs and rivaled OpenAI's closed-source GPT4-o.At the time, Liang Wenfeng, the CEO, reportedly said that he had hired young computer science researchers with a pitch to solve the hardest questions in the world"critically, without aiming for profits. Early signs were promising: his products were so efficient that DeepSeeks 2024 releases sparked a price war within the Chinese AI industry, forcing competitors to slash prices. This year, that price war looks set to reach across the Pacific Ocean.Yet DeepSeeks AI looks different from its U.S. competitors in one important way.What DeepSeeks success could mean for American tech giantsAt a moment when Google, Meta, Microsoft, Amazon and dozens of their competitors are preparing to spend further tens of billions of dollars on new AI infrastructure, DeepSeeks success has raised a troubling question: Could Chinese tech firms potentially match, or even surpass, their technical prowess while spending significantly less?Meta, which plans to spend $65 billion on AI infrastructure this year, has already set up four war rooms to analyze DeepSeeks models, seeking to find out how the Chinese firm had managed to train a model so cheaply and use the insights to improve its own open source Llama models, tech news site The Information reported over the weekend.In the financial markets, Nvidias stock price dipped more than 15% on Monday morning on fears that fewer AI chips may be necessary to train powerful AI than previously thought. Other American tech stocks were also trading lower.While [DeepSeek R1] is good news for users and the global economy, it is bad news for U.S. tech stocks, says Luca Paolini, chief strategist at Pictet Asset Management. It may result in a nominal downsizing of capital investment in AI and pressure on margins, at a time when valuation and growth expectations are very stretched.But American tech hasnt lostat least not yet.For now, OpenAIs o1 Pro model is still considered the most advanced in the world. The performance of DeepSeek R1, however, does suggest that China is much closer to the frontier of AI than previously thought, and that open-source models have just about caught up to their closed-source counterparts.Perhaps even more worrying for companies like OpenAI and Google, whose models are closed source, is how muchor rather, how littleDeepSeek is charging consumers to access its most advanced models. OpenAI charges $60 per million tokens, or segments of words, outputted by its most advanced model, o1. By contrast DeepSeek charges $2.19 for the same number of tokens from R1nearly 30 times less.It erodes the industrial base, it erodes the margin, it erodes the incentive for further capital investment into western [AI] scaling from private sources, says Edouard Harris, the chief technology officer of Gladstone AI, an AI firm that works closely with the U.S. government. but is Deepseek being transparent?DeepSeeks success was all the more explosive because it seemed to call into question the effectiveness of the U.S. governments strategy to constrain Chinas AI ecosystem by restricting the export of powerful chips, or GPUs, to Beijing. If DeepSeeks claims are accurate, it means China has the ability to create powerful AI models despite those restrictions, underlining the limits of the U.S. strategy. DeepSeek has claimed it is constrained by access to chips, not cash or talent, saying it trained its models v3 and R1 using just 2,000 second-tier Nvidia chips. Money has never been the problem for us, DeepSeeks CEO, Liang Wenfeng, said in 2024. Bans on shipments of advanced chips are the problem. (Current U.S. policy makes it illegal to export to China the most advanced types of AI chips, the likes of which populate U.S. datacenters used by OpenAI and Microsoft.)But are those claims true? My understanding is DeepSeek has 50,000 H100s, Scale AI CEO Alexandr Wang recently told CNBC in Davos, referring to the highest-powered Nvidia GPU chips currently on the market. They cant talk about [them], because it is against the export controls that the U.S. has put in place. (An H100 cluster of that size would cost in the region of billions of dollars.)In a sign of how seriously the CCP is taking the technology, Liang, Deepseeks CEO, met with Chinas premier Li Qiang in Beijing last Monday. In that meeting, Liang reportedly told Li that DeepSeek needs more chips. DeepSeek only has access to a few thousand GPUs, and yet theyre pulling this off, says Jeremie Harris, CEO of Gladstone AI. So this raises the obvious question: what happens when they get an allocation from the Chinese Communist Party to proceed at full speed? Even though China might have achieved a startling level of AI capability with fewer chips, experts say more computing power will always remain a strategic advantage. On that front, the U.S. remains far ahead. It's never a bad thing to have more of it, says Dean Ball, a research fellow at George Mason University. No matter how much you have of it, you will always use it.Where does this leave Americas tech rivalry with China?The short answer: from Washingtons perspective, in uncertain waters.In the closing days of the Biden Administration, outgoing National Security Adviser Jake Sullivan warned that the speed of AI advancement was the most consequential thing happening in the world right now. And just days into his new job, President Trump announced a new $500 billion venture, backed by OpenAI and others, to build the infrastructure vital for the creation of artificial general intelligence the next leap forward in AI, with systems advanced enough to make new scientific breakthroughs and reason in ways that have so far remained in the realm of science fiction.And although questions remain about the future of U.S. chip restrictions on China, Washingtons priorities were apparent in President Trumps AI executive order, also signed during his first week in office, which declared that it is the policy of the United States to sustain and enhance Americas global AI dominance in order to promote human flourishing, economic competitiveness, and national security. Maintaining this dominance will mean, at least in part, understanding exactly what Chinese tech firms are doingas well as protecting U.S. intellectual property, experts say.There's a good chance that DeepSeek and many of the other big Chinese companies are being supported by the [Chinese] government, in more than just a monetary way, says Edouard Harris of Gladstone AI, who also recommended that U.S. AI companies harden their security measures.Where does AI go from here?Since December, OpenAIs new o1 and o3 models have smashed records on advanced reasoning tests designed to be difficult for AI models to pass.DeepSeek R1 does something similar, and in the process exemplifies what many researchers say is a paradigm shift: instead of scaling the amount of computing power used to train the model, researchers scale the amount of time (and thus, computing power and electricity) the model uses to think about a response to a query before answering. It is this scaling of what researchers call test-time compute that distinguishes the new class of reasoning models, such as DeepSeek R1 and OpenAIs o1, from their less sophisticated predecessors. Many AI researchers believe theres plenty of headroom left before this paradigm hits its limit.Some AI researchers hailed DeepSeeks R1 as a breakthrough on the same level as DeepMinds AlphaZero, a 2017 model that became superhuman at the board games Chess and Go by purely playing against itself and improving, rather than observing any human games.Thats because R1 wasnt pretrained on human-labeled data in the same way as other leading LLMs.Instead, DeepSeeks researchers found a way to allow the model to bootstrap its own reasoning capabilities essentially from scratch.Rather than explicitly teaching the model on how to solve a problem, we simply provide it with the right incentives, and it autonomously develops advanced problem-solving strategies, they claim.The finding is significant because it suggests that powerful AI capabilities might emerge more rapidly and with less human effort than previously thought, with just the application of more computing power. DeepSeek R1 is like GPT-1 of this scaling paradigm, says Ball.Ultimately, Chinas recent AI progress, instead of usurping U.S. strength, might in fact be the beginning of a reorderinga step, in other words, toward a future where, instead of a hegemonic power, there are many competing centers of AI power.China will still have their own superintelligence(s) no more than a year later than the US, absent [for example] a war, wrote Miles Brundage, a former OpenAI policy staffer, on X. So unless you want (literal) war, you need to have a vision for navigating multipolar AI outcomes.

  • Element Six unveils copper-diamond composite for advanced thermal management
    www.techspot.com
    The big picture: Element Six has introduced a copper-plated diamond composite material designed to address increasing thermal management challenges in advanced semiconductor devices. By lowering temperatures, some chips could be fed more voltage and be pushed to run even faster. Synthetic diamond specialist Element Six, part of the De Beers Group (think diamond jewelry), said more than half of all electronic device failures today are heat-related. And considering that data centers are expected to account for 10 percent of the total US power demand by 2029, thermal management is becoming an ever-pressing matter.This is where E6's Cu-diamond composite comes into play. According to the company, its thermal conductivity is in the 800 W/mk range about twice as high as copper, but not quite as high as diamond on its own. Diamond, as you may know, is the leading thermally conductive material with conductivity values that are about five times that of copper.The Cu-diamond material can be manufactured into complex shapes with specific features, like holes or curves, to fit a variety of applications (think heatspreaders and other inserts designed to fit between a chip and its cooling solution). E6 noted that thermal conductivity and coefficient of thermal expansion can be fine-tuned by varying the copper-diamond composition to meet a client's specific needs.According to the company, it's also cost effective. It's hard to imagine anything with diamonds in it synthetic or natural being affordable, but we'll reserve judgement until pricing is revealed.Related reading: CPU makers are experimenting with alternative substrates to double clock speedsDon't expect to see this tech show up in consumer-grade hardware, at least not anytime soon. E6 expects the first applications to utilize the material to include high-end chips for AI processing, RF power amplifiers for wireless and defense communications, and powerful semiconductor lasers.Element Six will showcase its new material at the SPIE Photonics West conference for optics and photonics. The show starts on January 28 and runs through the 30th in San Francisco.
