Researchers at Cornell Tech have released a dataset extracted from more than 300,000 public Reddit communities, and a report detailing how Reddit communities are changing their policies to address a surge in AI-generated content. The team collected metadata and community rules from the online communities, known as subreddits, during two periods in July 2023 and November 2024. The researchers will present a paper with their findings at the Association of Computing Machinery's CHI conference on Human Factors in Computing Systems being held April 26 to May 1 in Yokohama, Japan. One of the researchers' most striking discoveries is the rapid increase in subreddits with rules governing AI use. According to the research, the number of subreddits with AI rules more than doubled in 16 months, from July 2023 to November 2024. "This is important because it demonstrates that AI concern is spreading in these communities.

On Wednesday, Anthropic released a report detailing how Claude was misused during March. It revealed some surprising and novel trends in how threat actors and chatbot abuse are evolving and the increasing risks that generative AI poses, even with proper safety testing. In one case, Anthropic found that a "sophisticated actor" had used Claude to help scrape leaked credentials "associated with security cameras" to access the devices, the company noted in the announcement. In another case, an individual with "limited technical skills" could develop malware that normally required more expertise. Claude helped this individual take an open-source kit from doing just the basics to more advanced software functions, like facial recognition and the ability to scan the dark web.

Elon Musk's artificial intelligence company is stirring controversy in Memphis, Tennessee. That's where he's building a massive supercomputer to power his company xAI. Community residents and environmental activists say that since the supercomputer was fired up last summer it has become one of the biggest air polluters in the county. But some local officials have championed the billionaire, saying he's investing in Memphis. The first public hearing with the health department is scheduled for Friday, where county officials will hear from all sides of the debate.

The House of Representatives, Japan's lower chamber of parliament, passed a bill on Thursday to promote the development of artificial intelligence technology and take steps to mitigate its risks. The legislation is expected to be enacted during the current parliamentary session set to end in June after deliberations at the House of Councilors, the upper chamber. AI "will be the foundation of economic and social development and is an important technology from the viewpoint of security," the bill said.

For now entrepreneurs are focussing their efforts on humanoid robots for warehouses and factories. The highest profile of those is Elon Musk. His car company, Tesla, is developing a humanoid robot called Optimus. In January he said that "several thousand" will be built this year and he expects them to be doing "useful things" in Tesla factories. Other carmakers are following a similar path.

AI company Perplexity announced in February that it was building its own browser called Comet. In a recent interview with the TBPN podcast, CEO Aravind Srinivas gave some insight as to why the business appeared to be branching out from its artificial intelligence focus: It's to collect user data and sell them targeted advertisements. "That's kind of one of the other reasons we wanted to build a browser, is we want to get data even outside the app to better understand you," he said. "We plan to use all the context to build a better user profile and, maybe you know, through our discover feed we could show some ads there." If that all sounds familiar, it could be become Google's Chrome browser has taken a similar approach.

Automakers and tech developers testing and deploying self-driving and advanced driver assistance features will no longer have to report as much detailed, public crash information to the federal government, according to a new framework released today by the US Department of Transportation. The moves are a boon for makers of self-driving cars and the wider vehicle technology industry, which has complained that federal crash reporting requirements are overly burdensome and redundant. But the new rules will limit the information available to those who watchdog and study autonomous vehicles and driver assistance features--tech developments that are deeply entwined with public safety but which companies often shield from public view because they involve proprietary systems that companies spend billions to develop. The government's new orders limit "one of the only sources of publicly available data that we have on incidents involving Level 2 systems," says Sam Abuelsamid, who writes about the self-driving vehicle industry and is the vice president of marketing at Telemetry, a Michigan research firm, referring to driver assistance features such as Tesla's Full Self-Driving (Supervised), General Motors' Super Cruise, and Ford's Blue Cruise. These incidents, he notes, are only becoming "more common."

Remember when Microsoft promised that the Copilot key would be the next big thing? Since then Microsoft has begun backing away from its Copilot app, and this week the company is promising that Copilot won't even launch when you tap the key -- just a subset of the app will. Instead, Microsoft is promising that the Copilot key -- or, in future, the WIN C shortcut -- will launch Copilot Chat, a small chat box that won't take up as much screen space as before. But even this new experience isn't free from Microsoft's fragmentation problems, which puts separate features on separate tracks. Microsoft has two Copilot experiences: the "consumer" version of Copilot, and the more professional Copilot experience as Microsoft 365 Copilot.

The California Supreme Court urged the State Bar of California Thursday to explain how and why it utilized artificial intelligence to develop multiple-choice questions for its botched February bar exams. California's highest court, which oversees the State Bar, disclosed Tuesday that its justices were not informed before the exam that the State Bar had allowed its independent psychometrician to use AI to develop a small subset of questions. The Court on Thursday upped its public pressure on the State Bar, demanding it explain how it used AI to develop questions -- and what actions it took to ensure the reliability of the questions. The demand comes as the State Bar petitions the court to adjust test scores for hundreds of prospective California lawyers who complained of multiple technical problems and irregularities during the February exams. Using AI-developed questions written by non-legally-trained psychometricians represents'an obvious conflict of interest,' critics say.

You've heard of AI models taking the bar exam, but this time, AI also helped write the questions. The State Bar of California revealed on Monday that it used AI to develop a portion of its exam questions, according to the LA Times. The AI-generated exam questions were created by an independent psychometrician called ACS Ventures hired by the State Bar. The questions were "developed with the assistance of AI and subsequently reviewed by content validation panels and a subject matter expert in advance of the exam," announced the State Bar in a statement addressing technical glitches and question errors that test takers had previously complained about. The LA Times reported that 23 out of the 171 multiple choice questions were made by ACS Ventures.
