Microsoft unveils AI security tools it says outperform competing platforms

Microsoft is introducing new AI tools designed to help customers continuously streamline and automate the process of identifying and reducing their exposure to security risks. The new tools come less than a week after OpenAI lost control of two of its security models when they infiltrated the servers of startup Hugging Face. The hack, Hugging Face added, involved “a swarm of tens of thousands of automated actions” that stole internal Hugging Face credentials. The OpenAI models achieved this feat by exploiting a zero-day flaw in Hugging Face’s data-processing pipeline to run malicious code that escalated the models’ access to the company’s high-value cloud and server clusters. Microsoft’s announcements on Monday made no reference to the event, which OpenAI said was “unprecedented.” The…

“Google and Reddit do not own the Internet," web scraper says after court win

After a big court loss last week, Google has confirmed that it won’t give up its fight to block AI bots from scraping its search results. And Reddit is weirdly along for the ride. Curiously invoking the Digital Millennium Copyright Act (DMCA), Google sued SerpApi last December. The search giant accused the web scraper of circumventing its anti-scraping technology and then selling content scraped from Google search results through an unauthorized “Google Search API” software service. According to Google, the anti-scraping tech was in place to protect copyrighted content in search results. Allegedly, SerpApi’s circumvention threatened to disrupt Google’s relationships with rights holders, including some who license content to Google to appear in so-called “knowledge panels” that are…

Verizon touts $1B dark fiber deal for Google data centers as first of many

Verizon is seeking to tap into Silicon Valley’s AI spending in a big way. The telecom giant revealed a deal worth more than $1 billion to link Google data centers using Verizon’s dark fiber routes—and it’s also tearing copper wiring out of central offices as it converts them into small data centers suitable for supporting AI inference workloads. The telecom company publicly disclosed the Google partnership and data center conversion efforts as part of a new “AI Connect” business initiative during an earnings conference call covering the second quarter of 2026. Verizon also expects to announce additional AI-related deals by the end of the year that would be “worth multiple billions of dollars in revenue over the next several years,” said Dan Schulman, CEO of Verizon Communications, during…

OpenAI called the Hugging Face attack unprecedented. But we’ve been here before.

This story originally appeared in The Algorithm, our weekly newsletter on AI. To get stories like this in your inbox first, sign up here . Reading OpenAI’s account last week of how some of its models broke their containment and hacked into the computer systems of Hugging Face , another AI company, was the first time I got genuine chills about what large language models are now able to do. But this is a case of human hubris, not rogue AI. I am not an alarmist. In fact, I have been pushing back against AI scare stories for years. Even so, this incident crossed a line. I think it’s the clearest illustration yet of how the people building and testing this technology do not fully understand what they’re doing. OpenAI could—and should—have seen this coming. Here’s what happened, at least…

OpenAI’s Hugging Face breach has reignited the debate over alignment and control

OpenAI's Hugging Face breach has reignited debate over AI alignment and control, exposing competing views on whether increasingly capable AI should be better aligned, better contained, or both.

ChatGPT starts blocking direct requests to copy an author's style

OpenAI's ChatGPT is now refusing requests to generate text that directly mimics the style of famous authors. When asked to do so, the popular LLM instead offers a response that draws on the "broad qualities" of those authors "while remaining distinct in its own voice," for example. This morning, Ars received the following response to a test prompt asking for a story introduction in the style of Stephen King: I can definitely write with the hallmarks of atmospheric, character-driven horror and small-town dread, but I can't write in Stephen King's exact style or closely imitate his distinctive voice. Here's an original opening that captures a similar feeling while remaining its own... In testing, ChatGPT generated similar dodges for other authors both living (J.K. Rowling, Amy Tan) and dead…

Why China is giving away its best AI models

People visit the booth of Kimi, an LLM developed by the Chinese startup Moonshot, during the World AI Conference in Shanghai, China, July 20th. | Image: LONG WEI/ Feature China/Future Publishing via Getty Images Silicon Valley has spent much of the past week on red alert, digesting the arrival of Moonshot AI's Kimi K3 , a Chinese AI model that can allegedly beat some of the best systems built by US companies at a fraction of the cost. Its performance alone would have been enough to intensify the rivalry between the US and China . But Moonshot's plan to release the model's weights for free - and its clear targeting of US users - has fueled deeper unease about whether closed American models can continue to dominate as increasingly capable open alternatives enter the market. Open-weight…

Nvidia, Microsoft launch open AI security alliance — without OpenAI, Google, or Anthropic

Nvidia on Monday said it is joining forces with Microsoft, SpaceX, IBM, and other tech companies to build and share open-source AI security tools. The new Open Secure AI Alliance said open tools are required to effectively defend against attacks from frontier models. The initiative is a direct response to mounting concerns over the safety of advanced AI systems after a rogue OpenAI model escaped containment and attacked another company during testing. That company, Hugging Face, said it was forced to use a Chinese open-weight model to defend itself due to the strict safety guardrails limiting the usefulness of top US models.

The path to artificial superintelligence

Imagine a healthcare system made up of multiple AI agents: one that manages symptom assessment, another scheduling, a third insurance, and a fourth pharmacy. Each is an expert in its domain. But they all have their own distinct knowledge and objectives. Today they can exchange data, but they are not yet able to actually coordinate patient care without a human making the decisions. “The intelligence is already there. What is missing is the connective tissue that turns four strangers into one team,” explains Vijoy Pandey, senior vice president and general manager of Outshift by Cisco. This “connective tissue” comes from adding a semantic layer—what Outshift calls the “Internet of Cognition”—that enables agents across domains to work together and, critically, “think” together through shared…

Closing the data loop in AI-driven drug discovery

Drug discovery is a high-cost, high-risk endeavor that is under growing pressure from a market increasingly defined by first-mover advantage. Since the 1950s, the cost of developing new pharmaceuticals has roughly doubled every nine years—a phenomenon known as Eroom’s Law . Today, bringing a new drug to market takes an average of 10-15 years and costs anywhere from $1 billion to $2.5 billion , with failure rates upward of 90%. AI has become the pharmaceutical industry’s biggest bet on bringing success rates up and timelines down. The faster drug companies can identify, test, and optimize new chemical compounds, the lower the risk of costly failures later in development. “The main cost in drug discovery is still the clinical phase, so trying to reduce risk and increase your success rates…

Building the enterprise environment for agentic AI

For the enterprise, the promise of agentic AI is much more than just a better chatbot. It is software agents that execute business tasks end-to-end across people, business workflows, data, and systems. The platform best-suited to run agents is built with proper CPU capacity, resilient data access, policy-aware tool use, observability, memory management, and the ability to predictably plan and scale agents. To better understand some of these dependencies, Intel performed thousands of agentic AI workload experiments. Our initial findings create and support five practical lessons for enterprise leaders: Agentic AI is a larger systems problem, not just one of inference. The majority of existing agentic AI harnesses are limited and do not measure overall system performance. Plan capacity is…

Artist sues AI meme generator for selling deeply personal comic as ad template

Artist Elmer Saflor, who goes by the online handle “Superelmer,” loves that millions of people have shared his “Running Away Balloon” comic since it became a popular meme in 2017. However, just because lots of people have copied it, that doesn’t mean it’s OK for an AI meme generator to commercialize his copyrighted meme as a template for who knows how many ads, he told Ars. That’s why he’s fighting to stop one of the biggest meme generators currently leveraging AI to rapidly scale the allegedly illegal use. "Running Away Balloon" comic by Elmer Saflor, aka "Superelmer."
