When the transformer architecture was introduced in 2017 in the now seminal Google paper "Attention Is All You Need," it became an instant cornerstone of modern artificial intelligence. Every major large language model (LLM) — from OpenAI's GPT series to Anthropic's Claude, Google's Gemini, and Meta's Llama — has been built on some variation of its central mechanism: attention, the mathematical operation that allows a model to look back across its entire input and decide what information matters most.Eight years later, the same mechanism that defined AI’s golden age is now showing its limits. Attention is powerful, but it is…

Elephant trunks and garden hoses hardly seem like inspirations for a miniature 3D bioprinter.Yet they’ve led scientists at McGill University to engineer the smallest reported bioprinting head to date. Described in the journal Devices, the device has a flexible tip just 2.7 millimeters in diameter—roughly the length of a sesame seed.Bioprinters can deposit a wide range of healing materials directly at the site of injury. Some bioinks combat infections in lab studies; others deliver chemotherapy to cancerous sites, which could prevent tumors from recurring. On the operating table, biocompatible hydrogels injected during surgery help heal wounds.The devices are promising but…

Samsung Galaxy XR: Two-minute reviewI think I finally understand why Apple’s Vision Pro costs so darn much. The Samsung Galaxy XR delivers moments of beauty and inspiration, but it’s also stuffed full of disappointment, from the sound of fans on your face to imprecision of gestures to a total lack of ‘wow’ apps and experiences.Yes, Gemini is in there, and I spent a lot of time with it riding…

If you’re anything like me, you probably have a drawer full of tangled cables. But despite owning multiple charging cables, the constant issue I had was juggling three or four cables to keep everything powered. It’s messy, frustrating, and has caught me off guard in multiple instances when I’m away but don’t have an appropriate cable to top up a certain device, whether it’s my phone, power bank, headphones, earbuds, or feature phone. That’s why finding a cable that charges nearly everything I own felt like hitting the tech jackpot. Nowadays, I no longer rummage through drawers or carry a…

I am a big fan of the LG StanbyME line. These monitors blur the lines between monitors and TVs, offering a more seamless experience with wireless capabilities. They are fantastic, especially if you can get them on sale. Today, the LG StanbyME 27-inch Portable Monitor is at a record-low price, saving you $203! Buy the LG StanbyMe 27-Inch Portable Monitor for just $796.99 ($203 off)This offer is available from Amazon as a “limited time deal.” This is the first-generation LG StanbyME, but it is by no means an outdated monitor. The LG StanbyMe 27-inch Portable Monitor remains a great option,…

The intelligence of AI models isn't what's blocking enterprise deployments. It's the inability to define and measure quality in the first place.That's where AI judges are now playing an increasingly important role. In AI evaluation, a "judge" is an AI system that scores outputs from another AI system. Judge Builder is Databricks' framework for creating judges and was first deployed as part of the company's Agent Bricks technology earlier this year. The framework has evolved significantly since its initial launch in response to direct user feedback and deployments.Early versions focused on technical implementation but customer feedback revealed the real bottleneck was…

Investors are increasingly becoming concerned that AI companies may be grossly overvalued — and could struggle to justify their enormous hype by successfully ratcheting up profits. So it’s naturally alarming that shares of AI industry stalwarts, including Oracle, Nvidia, AMD, and Amazon, fell sharply on Tuesday, following concerns over enormous valuations that have propped up the entire US economy for months now. AI chipmaker Nvidia’s shares dipped just shy of four percent, while competitor AMD’s slid just under three percent today. Software giant Palantir was hit hardest, dropping over nine percent, despite beating Wall Street expectations with its Q3 earnings.…

Verdict The Boya Mini is a capable set of tiny lapel mics for a budget price with clear and rich pickup and surprisingly effective noise reduction. They’re also easily portable and provide good battery life. You are making sacrifices on control, recording quality, and wireless range against dearer rivals, though. Very small and portable Surprisingly solid pickup Good battery life Cheaper feel Some may want more pro-grade recording powers Key Features 5g weight The Boya Mini makes for one of the smallest microphone sets available, with the individual transmitters weighing just five grams. 30 hours battery life The kit’s total…

The most widely cited statistic from a new MIT report has been deeply misunderstood. While headlines trumpet that "95% of generative AI pilots at companies are failing," the report actually reveals something far more remarkable: the fastest and most successful enterprise technology adoption in corporate history is happening right under executives' noses.The study, released this week by MIT's Project NANDA, has sparked anxiety across social media and business circles, with many interpreting it as evidence that artificial intelligence is failing to deliver on its promises. But a closer reading of the 26-page report tells a starkly different story — one…

It’s a regular joke in the tech biz these days, but it’s true — often, we forget that our smartphones are supposed to make phone calls. It’s easier to shoot someone an email or a text message, and phones serve a million other purposes, from games and fitness tracking to social media and recording rides. The way Apple’s marketing goes, you’d think most Hollywood movies were shot using iPhones. If you actually do want to use your Android phone for its nominal purpose, there are a number of settings you can change to get the most out of it. Note…
