  • OpenAI Mulls Slashing Prices As It Competes With Anthropic For Users
    by BeauHD on 11/06/2026 at 6:00 pm

    OpenAI is reportedly considering sharp price cuts for paid access to its AI models as competition with Anthropic intensifies and both companies race for users ahead of potential IPOs. "The company is weighing significant cuts to what it charges for tokens, the unit of measurement artificial-intelligence firms use to bill for their products," the Wall Street Journal said, adding that it was "in anticipation of similar cuts the company expects at Anthropic." CNBC reports: The ChatGPT producer, which did not immediately respond to CNBC's requests for comment, currently charges consumers in tiered subscriptions of $8, $20 and $100 and above each month for access to its flagship GPT-5.5 models. Anthropic conversely charges users $17 each month with an annual subscription to Claude Pro, and $100 and above monthly for a subscription to Claude Max. OpenAI confidentially filed for an IPO on Monday, just a week after Anthropic made its own filing. Read more of this story at Slashdot.

  • Opendoor Ends India Operations, Fueling a Bigger Conversation About AI and Outsourcing
    by BeauHD on 11/06/2026 at 5:00 pm

    Opendoor is shutting down its India operations less than two years after opening offices there. Slashdot reader alternative_right shares a post from Opendoor CEO Kaz Nejatian: "I shared this note earlier today with the entire team at Opendoor. Today we began to say goodbye to our colleagues in India as we wind down our India operations. Our customers are in America, and that's where our operational work belongs." TechCrunch reports: In announcing the decision on Wednesday, CEO Kaz Nejatian cited a push to bring operational work back to the U.S., where Opendoor's customers are, and a shift toward smaller AI-native teams. The company did not respond to requests for comment on how many employees were affected or how much of the decision was driven by AI efficiency. But the announcement quickly gained traction across Silicon Valley, where founders, investors, and outsourcing experts see it as an early example of how AI is reshaping the economics that made India a global hub for back-office operations. [...] Some investors viewed the decision as a sign of what AI could mean for India's vast outsourcing workforce. "As manual work gets replaced by AI, a lot of jobs will be lost in India," wrote Sheel Mohnot, co-founder of Better Tomorrow Ventures. Others viewed Opendoor as evidence of a larger shift in how companies are organized. Keshav Lohia, a venture capitalist at Emergent Ventures, described the decision as a "watershed moment" for AI-driven operations, arguing that advances in AI are beginning to challenge the cost-arbitrage model that made India a popular offshoring destination. Phil Fersht, chief executive of HFS Research, an advisory firm that tracks the global outsourcing and business services industry, told TechCrunch that the development should not be viewed simply as jobs moving from India to the U.S. The more important shift, he said, is that AI is reducing the amount of operational labor companies require in the first place, allowing firms to run leaner organizations regardless of location. "This is not an isolated restructuring," Fersht said. "It is part of a much broader pattern we are starting to see as companies redesign operations around AI, automation, and much leaner workflows." Fersht argued that the winners would be companies that combine AI, software and human expertise to deliver outcomes without continually adding headcount, a model he described as "Services-as-Software." While Opendoor may be one of the first high-profile examples, he said it is unlikely to be the last. Some investors are already extrapolating beyond individual companies. Varun Rekhi, a venture capitalist at Speedinvest, argued that if AI reduces demand for labor-intensive services, it could eventually pressure one of India's most important export industries, which is built around supplying talent and expertise to global corporations.

  • Xbox CEO Says Current Margins 'Cannot Continue'
    by BeauHD on 11/06/2026 at 4:00 pm

    Xbox CEO Asha Sharma and Chief Content Officer Matt Booty told staff that Xbox's current economics "cannot continue," citing more than $20 billion in spending over five years, declining revenue outside Activision Blizzard King, console supply constraints tied to RAMaggedon, and an overextended studio portfolio. The memo stops short of announcing layoffs, but a Bloomberg report says substantial Xbox cuts are expected after Microsoft's fiscal year ends on June 30. Engadget reports: The takeaways are pretty grim. For starters, the simple math of Xbox's revenue isn't adding up to success. "Excluding Activision Blizzard King, over the past five years, we have spent over $20 billion on ongoing investments in our content, platform, and hardware subsidy, but our annual revenue has declined nearly half a billion during that time," the execs state. "Going forward, this cannot continue." They also acknowledge the impact of RAMaggedon: "We are currently unable to make as many consoles as players want to buy, and we need a new business model and partnerships for hardware as we remain committed to Helix." (Helix, in this case, is Project Helix, the codename for Xbox's new console.) Then there's the kicker, a renewed admission that Xbox still can't support the many studios it acquired in the late 2010s in an effort to grow its first-party game ambitions. "We have found ourselves over extended as we executed on changing strategies in a landscape of more readily available content," the pair said, noting elsewhere that with so many good games, not to mention the plethora of other forms of entertainment available, "Going forward, our competition is attention."

  • OpenAI Says China Launched Influence Campaign To Shape US Attitudes On AI Datacenters
    by BeauHD on 11/06/2026 at 3:00 pm

    An anonymous reader quotes a report from Politico: China was likely behind an online influence operation to sway U.S. perceptions of artificial intelligence technology and reshape the debate in Washington around the infrastructure needed to support it, according to research from OpenAI published Wednesday. OpenAI said it caught the influence campaign because China-backed operatives were using ChatGPT to create content for the social media campaign. [...] OpenAI's researchers identified two clusters of ChatGPT users "likely originating from China" who used the AI chatbot to generate social media content "in support of apparent covert influence operations" promoting certain narratives about AI. This includes claims that data center build-outs are raising electricity costs for the average American family and that President Donald Trump has weaponized tariffs to keep the U.S. ahead in the global tech race. These accounts have since been banned, the report said. One cluster of users asked ChatGPT to generate images and comments pushing these narratives. These comments were then posted on social media by "batches of accounts" posing as Americans, [said Ben Nimmo, principal investigator of intelligence and investigations at OpenAI]. Another cluster identified by researchers used AI to generate social media content criticizing the Trump administration's tariffs as an attempt to "dominate technological competition." Prompts used for this campaign were submitted in Simplified Chinese and asked that AI-generated content not include Chinese President Xi Jinping and focus solely on Trump -- a possible tell that China was behind the operation, according to the report. Nimmo said that the influence campaign amplified existing public backlash in the U.S. against the creation of new AI data centers, which has resulted in dozens of proposed moratoriums at the local, state and national level. "Neither campaign appears to have gained much authentic engagement," Nimmo said. "They're important for what they reveal about the intentions of influence operators from China, and the narratives they're testing and seeking to amplify, but not for the impact."

  • Fully Autonomous Drones Have Killed Human Soldiers For the First Time
    by BeauHD on 11/06/2026 at 11:00 am

    Longtime Slashdot reader MattSparkes shares a report from NewScientist, captioned: "For years we've had unconfirmed reports, rumors, hints... now we know." From the report: Fully autonomous drones with no human oversight have killed soldiers on the battlefield for the first time. This is according to a senior figure in the Ukrainian defense industry, marking a watershed moment in warfare. The one-off test involved 10 AI-controlled "Terminator" drones on the front line of the Ukraine war. Russian soldiers were killed. "We tried it," says drone-maker Alexander Kokhanovskyy, who supplied the technology and spoke to New Scientist at a press event hosted by the Ukrainian embassy. "It's a test. We never implemented it [more widely]." The test took place two years ago and involved quadcopter drones that were programmed to fly towards the front line, cover between 3 and 5 kilometres over around 10 minutes and then engage "Terminator mode," in which an AI model searches for and intercepts targets. "We just launch it and we know everything will be dead -- everything that will be found there in this particular area will be dead," says Kokhanovskyy. "There is no connection to the drone at all, you cannot see the video, nothing... Everything it sees will be killed." With no way to tell what the automated drones had seen or targeted, human-piloted drones were sent into the area after the test to manually check results. Victims included "a couple of soldiers, one truck," says Kokhanovskyy. While there is no recording of the automated drones attacking these targets, it was concluded that the drones had killed them. Kokhanovskyy says that he was not at the test personally but that it was carried out by an unnamed military unit near the cities of Bakhmut and Chasiv Yar as part of a Ukrainian counteroffensive push. The Ukrainian Ministry of Defence did not respond to questions about the test or the current legal position on the use of fully autonomous weapons. Read more of this story at Slashdot.

  • Humans Prefer To Walk Anticlockwise, Scientists Find
    by BeauHD on 11/06/2026 at 7:00 am

    fjo3 shares a report from The Guardian: Tests reveal that when people are ambling about, they have a natural tendency to turn to the left and walk in an anticlockwise direction. "If you simply ask someone to start walking, whether they are wandering around a museum, a supermarket, or even an empty room, it is surprisingly likely that they will drift counterclockwise," said Dr Inaki Echeverria Huarte at University of Navarra in Spain. As with many critical discoveries in science, the revelation owes a debt to serendipity. During the pandemic, the researchers ran experiments to see how many people could share a space while keeping a safe distance. On reviewing the video, they noticed that crowds overwhelmingly walked in an anticlockwise direction. The surprise set in motion an entire research project. The scientists conducted a series of experiments in which individual pedestrians or small crowds roamed around enclosed spaces. Time and again, the researchers observed the tendency to walk in an anticlockwise direction. Suspecting that cultural norms might play a role, the team joined forces with Dr Claudio Feliciani at the University of Tokyo. He found the same results in Japan. The finding held when the researchers accounted for people being right-handed, right-footed and right-eye dominant, and was seen in both male and female walkers. The only difference they spotted was a more pronounced bias in children. "Each of us carries a small personal bias to turn slightly to one side, and when many people share a space, those tiny biases add up into a net counterclockwise rotation," said Echeverria Huarte. Researchers think the tendency may be tied to biomechanics: people are not perfectly symmetrical, and the way the brain processes sensory information and coordinates muscles may gently tip walkers toward one side. Right-side dominance may also play a role, especially in running, where anticlockwise movement puts more internal force on the right side of the body and may feel more natural to right-leg-dominant athletes. "We have tested several ideas and the bias stubbornly keeps showing up, so the exact mechanism is still an open question," said Echeverria Huarte. The findings have been published in Nature Communications. Read more of this story at Slashdot.
