There's no shortage of generative AI benchmarks designed to measure the performance and accuracy of a given model on completing various helpful enterprise tasks — from coding to instruction following to agentic web browsing and tool use. But many of these benchmarks have one major shortcoming: they measure the AI's ability to complete specific problems and requests, not how the model is in its outputs — how well it generates objectively correct information tied to real-world data — especially when dealing with information contained in imagery or graphics. For industries where accuracy is paramount — legal, finance, and medical — the lack of a standardized way to measure has been a critical blind spot. That changes today: Google’s FACTS team and its data science unit Kaggle released the FACTS Benchmark Suite, a comprehensive evaluation framework designed to close this gap. The associated research paper reveals a more nuanced definition of the problem, splitting

Mark Zuckerberg has for months publicly hinted that he is backing away from open-source AI models. Now, Meta's latest AI pivot is starting to come into focus. The company is reportedly working on a new model, known inside of Meta as "Avocado," which could mark a major shift away from its previous open-source approach to AI development.  Both CNBC and Bloomberg have reported on Meta's plans surrounding "Avocado," with both outlets saying the model "could" be proprietary rather than open-source. Avocado, which is due out sometime in 2026, is being worked on inside of "TBD," a smaller group within Meta's AI Superintelligence Labs that's headed up by  Chief AI Officer Alexandr Wang, who apparently favors closed models. It's not clear what Avocado could mean for Llama. Earlier this year, Zuckerberg said he expected Meta would "continue to be a leader" in open source but that it wouldn't "open

An international team of astronomers observed a sudden outburst of matter near the supermassive black hole NGC 3783 at speeds reaching up to 20% of the speed of light. During a ten-day observation, mainly with the XRISM space telescope, the researchers witnessed its formation and acceleration. Scientists often find that these outbursts are powered by strong radiation, but this time the most likely cause is a sudden change in the magnetic field, similar to bursts on the Sun that cause solar flares.

For more than a decade, Nvidia’s GPUs have underpinned nearly every major advance in modern AI. That position is now being challenged.  Frontier models such as Google’s Gemini 3 and Anthropic’s Claude 4.5 Opus were trained not on Nvidia hardware, but on Google’s latest Tensor Processing Units, the Ironwood-based TPUv7. This signals that a viable alternative to the GPU-centric AI stack has already arrived — one with real implications for the economics and architecture of frontier-scale training. Nvidia's CUDA (Compute Unified Device Architecture), the platform that provides access to the GPU's massive parallel architecture, and its surrounding tools have created what many have dubbed the "CUDA moat"; once a team has built pipelines on CUDA, switching to another platform is prohibitively expensive because of the dependencies on Nvidia’s software stack. This, combined with Nvidia's first-mover advantage, helped the company achieve a staggering 75% gross

SAN FRANCISCO — Self-driving Waymo taxis have gone viral for negative reasons involving the death of a beloved San Francisco bodega cat and pulling an illegal U-turn in front of police who were unable to issue a ticket to a nonexistent driver. But this week, the self-driving taxis are the bearer of happier news after a San Francisco woman gave birth in a Waymo. The mother was on her way to the University of California, San Francisco medical center Monday when she delivered inside the robotaxi, said a Waymo spokesperson in a statement Wednesday. The company said its rider support team detected “unusual activity” inside the vehicle and called to check on the rider as well as alert 911. Waymo, which is owned by Google’s parent company, Alphabet, declined to elaborate on how the vehicle knew something was amiss. The taxi and its passengers arrived safely at the hospital ahead of emergency services. Jess Berthold, a UCSF spokesperson, confirmed the mother and child were brought to the

Ever since reporting earlier this year on how easy it is to trick an agentic browser, I've been following the intersections between modern AI and old-school scams. Now, there's a new convergence on the horizon: hackers are apparently using AI prompts to seed Google search results with dangerous commands. When executed by unknowing users, these commands prompt computers to give the hackers the access they need to install malware. The warning comes by way of a recent report from detection-and-response firm Huntress. Here's how it works. First, the threat actor has a conversation with an AI assistant about a common search term, during which they prompt the AI to suggest pasting a certain command into a computer's terminal. They make the chat publicly visible and pay to boost it on Google. From then on, whenever someone searches for the term, the malicious instructions will show up high on the first page of results. Huntress ran tests on both ChatGPT and Grok after

Meta's next AI model could mark a change in its "open source" AI strategy that Mark Zuckerberg had called "the path forward." Currently, the company is working on a new AI model, code-named Avocado, that it might charge for access to, Bloomberg reports. Last year, Meta launched its open source (depending on who you ask, since the Open Source Initiative disagrees) Llama 4 AI model, but it had a disappointing release, with Meta caught gaming AI benchmarks and being forced to delay a planned "Behemoth" version. But Zuckerberg scrapped that "in pursuit of something new," Bloomberg says. Following the Llama 4 launch, Zuckerberg has made sweepi … Read the full story at The Verge.

The early universe was a pretty intense place to be. And not just “early” as in a few billion years ago. I mean early early, just a few seconds after the Big Bang. The universe is small, less than a meter across. It’s hot, with temperatures so high it doesn’t even make sense to say them – they’re just stupidly high numbers with no connection to our everyday existence.

If quantum computing is going to become an every-day reality, we need better superconducting thin films, the hardware that enables storage and processing of quantum information. Too often, these thin films have impurities or other defects that make them useless for real quantum computer chips.

Producing fusion energy requires heating plasma to more than one hundred million degrees and confining it stably with strong magnetic fields. However, plasma naturally develops fluctuations known as turbulence, and they carry heat outward and weaken confinement. Understanding how heat and turbulence spread is therefore essential.

Neutrinos are one of the most mysterious particles in the universe, often called "ghost particles" because they rarely interact with anything else. Trillions stream through our bodies every second, yet leave no trace. They are produced during nuclear reactions, including those that take place in the core of our sun.

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of the universe's mass. Over the past decades, many physicists worldwide have been trying to detect this type of matter or signals associated with its presence, employing various approaches and technologies.
