In sci-fi films, the rise of humanlike artificial intelligence often comes hand in hand with a physical platform, such as an android or robot. While the most advanced AI language models so far seem mostly like disembodied voices echoing from an anonymous data center, they might not remain that way for long. Some companies like Google, Figure, Microsoft, Tesla, Boston Dynamics, and others are working toward giving AI models a body. This is called “embodiment,” and AI chipmaker Nvidia wants to accelerate the process.

“Building foundation models for general humanoid robots is one of the most exciting problems to solve in AI today,” said Nvidia CEO Jensen Huang in a statement. Huang spent a portion of Nvidia’s annual GTC conference keynote on Monday going over Nvidia’s robotics efforts. “The next generation of robotics will likely be humanoid robotics,” Huang said. “We now have the necessary technology to imagine generalized human robotics.”

To that end, Nvidia announced Project GR00T, a general-purpose foundation model for humanoid robots. As a type of AI model itself, Nvidia hopes GR00T (which stands for “Generalist Robot 00 Technology” but sounds a lot like the famous Marvel character) will serve as an AI mind for robots, enabling them to learn skills and solve various tasks on the fly. In a tweet, Nvidia researcher Linxi “Jim” Fan called the project “our moonshot to solve embodied AGI in the physical world.”

There’s a new boss at a storied 47-year-old Formula 1 team, and he’s eager to shake things up. He’s been saying that the team is far behind its competition in technology and coordination. And Excel is a big part of it.

Starting in early 2023, Williams team principal James Vowles and chief technical officer Pat Fry started reworking the F1 team’s systems for designing and building its car. It would be painful, but the pain would keep the team from falling even further behind. As they started figuring out new processes and systems, they encountered what they considered a core issue: Microsoft Excel.

The Williams car build workbook, with roughly 20,000 individual parts, was “a joke,” Vowles recently told The Race. “Impossible to navigate and impossible to update.” This colossal Excel file lacked information on how much each of those parts cost and the time it took to produce them, along with whether the parts were already on order. Prioritizing one car section over another, from manufacture through inspection, was impossible, Vowles suggested.

The Biden administration on Tuesday warned the nation’s governors that drinking water and wastewater utilities in their states are facing “disabling cyberattacks” by hostile foreign nations that are targeting mission-critical plant operations.

“Disabling cyberattacks are striking water and wastewater systems throughout the United States,” Jake Sullivan, assistant to the President for National Security Affairs, and Michael S. Regan, administrator of the Environmental Protection Agency, wrote in a letter. “These attacks have the potential to disrupt the critical lifeline of clean and safe drinking water, as well as impose significant costs on affected communities.”

The letter cited two recent hacking threats water utilities have faced from groups backed by hostile foreign countries. One incident occurred when hackers backed by the government of Iran disabled operations gear used in water facilities that still used a publicly known default administrator password. The letter didn’t name the facility by name, but details included in a linked advisory tied the hack to one that struck the Municipal Water Authority of Aliquippa in western Pennsylvania last November. In that case, the hackers compromised a programmable logic controller made by Unitronics and made the device screen display an anti-Israeli message. Utility officials responded by temporarily shutting down a pump that provided drinking water to local townships.

On Monday, Nvidia unveiled the Blackwell B200 tensor core chip—the company’s most powerful single-chip GPU, with 208 billion transistors—which Nvidia claims can reduce AI inference operating costs (such as running ChatGPT) and energy consumption by up to 25 times compared to the H100. The company also unveiled the GB200, a “superchip” that combines two B200 chips and a Grace CPU for even more performance.

The news came as part of Nvidia’s annual GTC conference, which is taking place this week at the San Jose Convention Center. Nvidia CEO Jensen Huang delivered the keynote Monday afternoon. “We need bigger GPUs,” Huang said during his keynote. The Blackwell platform will allow the training of trillion-parameter AI models that will make today’s generative AI models look rudimentary in comparison, he said. For reference, OpenAI’s GPT-3, launched in 2020, included 175 billion parameters. Parameter count is a rough indicator of AI model complexity.

Nvidia named the Blackwell architecture after David Harold Blackwell, a mathematician who specialized in game theory and statistics and was the first Black scholar inducted into the National Academy of Sciences. The platform introduces six technologies for accelerated computing, including a second-generation Transformer Engine, fifth-generation NVLink, RAS Engine, secure AI capabilities, and a decompression engine for accelerated database queries.

On Monday, Bloomberg reported that Apple is in talks to license Google’s Gemini model to power AI features like Siri in a future iPhone software update coming later in 2024, according to people familiar with the situation. Apple has also reportedly conducted similar talks with ChatGPT maker OpenAI.

The potential integration of Google Gemini into iOS 18 could bring a range of new cloud-based (off-device) AI-powered features to Apple’s smartphone, including image creation or essay writing based on simple prompts. However, the terms and branding of the agreement have not yet been finalized, and the implementation details remain unclear. The companies are unlikely to announce any deal until Apple’s annual Worldwide Developers Conference in June.

Gemini could also bring new capabilities to Apple’s widely criticized voice assistant, Siri, which trails newer AI assistants powered by large language models (LLMs) in understanding and responding to complex questions. Rumors of Apple’s own internal frustration with Siri—and potential remedies—have been kicking around for some time. In January, 9to5Mac revealed that Apple had been conducting tests with a beta version of iOS 17.4 that used OpenAI’s ChatGPT API to power Siri.

Japan-based IT behemoth Fujitsu said it has discovered malware on its corporate network that may have allowed the people responsible to steal personal information from customers or other parties.

“We confirmed the presence of malware on several of our company’s work computers, and as a result of an internal investigation, it was discovered that files containing personal information and customer information could be illegally taken out,” company officials wrote in a March 15 notification that went largely unnoticed until Monday. The company said it continued to “investigate the circumstances surrounding the malware’s intrusion and whether information has been leaked.” There was no indication how many records were exposed or how many people may be affected.

Fujitsu employs 124,000 people worldwide and reported about $25 billion in its fiscal 2023, which ended at the end of last March. The company operates in 100 countries. Past customers include the Japanese government. Fujitsu’s revenue comes from sales of hardware such as computers, servers, and telecommunications gear, storage systems, software, and IT services.

Starting in May, Dell employees who are fully remote will not be eligible for promotion, Business Insider (BI) reported Saturday. The upcoming policy update represents a dramatic reversal from Dell’s prior stance on work from home (WFH), which included CEO Michael Dell saying: “If you are counting on forced hours spent in a traditional office to create collaboration and provide a feeling of belonging within your organization, you’re doing it wrong.”

Dell employees will mostly all be considered “remote” or “hybrid” starting in May, BI reported. Hybrid workers have to come into the office at least 39 days per quarter, Dell confirmed to Ars Technica, which equates to approximately three times a week. Those who would prefer to never commute to an office will not “be considered for promotion, or be able to change roles,” BI reported.

“For remote team members, it is important to understand the trade-offs: Career advancement, including applying to new roles in the company, will require a team member to reclassify as hybrid onsite,” Dell’s memo to workers said, per BI.

On Sunday, Elon Musk’s AI firm xAI released the base model weights and network architecture of Grok-1, a large language model designed to compete with the models that power OpenAI’s ChatGPT. The open-weights release through GitHub and BitTorrent comes as Musk continues to criticize (and sue) rival OpenAI for not releasing its AI models in an open way.

Announced in November, Grok is an AI assistant similar to ChatGPT that is available to X Premium+ subscribers who pay $16 a month to the social media platform formerly known as Twitter. At its heart is a mixture-of-experts LLM called “Grok-1,” clocking in at 314 billion parameters. As a reference, GPT-3 included 175 billion parameters. Parameter count is a rough measure of an AI model’s complexity, reflecting its potential for generating more useful responses.

xAI is releasing the base model of Grok-1, which is not fine-tuned for a specific task, so it is likely not the same model that X uses to power its Grok AI assistant. “This is the raw base model checkpoint from the Grok-1 pre-training phase, which concluded in October 2023,” writes xAI on its release page. “This means that the model is not fine-tuned for any specific application, such as dialogue,” meaning it’s not necessarily shipping as a chatbot. But it will do next-token prediction, meaning it will complete a sentence (or other text prompt) with its estimation of the most relevant string of text.

Researchers have discovered a new way to hack AI assistants that uses a surprisingly old-school method: ASCII art. It turns out that chat-based large language models such as GPT-4 get so distracted trying to process these representations that they forget to enforce rules blocking harmful responses, such as those providing instructions for building bombs.

ASCII art became popular in the 1970s, when the limitations of computers and printers prevented them from displaying images. As a result, users depicted images by carefully choosing and arranging printable characters defined by the American Standard Code for Information Interchange, more widely known as ASCII. The explosion of bulletin board systems in the 1980s and 1990s further popularized the format.

Five of the best-known AI assistants—OpenAI’s GPT-3.5 and GPT-4, Google’s Gemini, Anthropic’s Claude, and Meta’s Llama—are trained to refuse to provide responses that could cause harm to the user or others or further a crime or unethical behavior. Prompting any of them, for example, to explain how to make and circulate counterfeit currency is a no-go. So are instructions on hacking an Internet of Things device, such as a surveillance camera or Internet router.

Thirteen countries across Africa experienced Internet outages on Thursday due to damage to submarine fiber optic cables. Some countries, including Ghana and Nigeria, are still suffering from nationwide outages.

Multiple network providers reported Internet outages yesterday, and Cloudflare’s Radar tool, which monitors Internet usage patterns, detailed how the outage seemingly moved from the northern part of West Africa to South Africa. All 13 countries (Benin, Burkina Faso, Cameroon, Côte d’Ivoire, Ghana, Guinea, Liberia, Namibia, Niger, Nigeria, South Africa, The Gambia, and Togo) reportedly suffered nationwide outages, with most seeing multiple networks hit.

Some countries’ Internet disruptions were short-lived, such as in Gambia and Guinea, as they lasted for 30 minutes, per Cloudflare. Other outages, like in South Africa (five hours) were longer, and some remain ongoing. As of this writing, Cloudflare reports that six countries, including Benin, Burkina Faso, Cameroon, and Côte d’Ivoire, are still suffering outages.
