EdgeCortix, a Tokyo-based artificial intelligence (AI) chip startup, is riding a wave of interest to foster Japanese semiconductors with defense applications. EdgeCortix, which has won a contract tied to the U.S. Department of Defense, on Wednesday secured government subsidies of 3 billion ( 21 million) to develop energy-efficient AI chiplets for commercialization in 2027. The contract may help revenue more than double this year, founder Sakyasingha Dasgupta said. The products, designed to help robots make real-time decisions and fill the country's labor shortages, target mass production at Taiwan Semiconductor Manufacturing Co.'s plant in Japan. The subsidies are on top of 4 billion in support the semiconductor designer won in November to make chips for next-generation communication systems.

Today, OpenAI is announcing that its technology will be deployed directly on the battlefield. The company says it will partner with the defense-tech company Anduril, a maker of AI-powered drones, radar systems, and missiles, to help US and allied forces defend against drone attacks. OpenAI will help build AI models that "rapidly synthesize time-sensitive data, reduce the burden on human operators, and improve situational awareness" to take down enemy drones, according to the announcement. Specifics have not been released, but the program will be narrowly focused on defending US personnel and facilities from unmanned aerial threats, according to Liz Bourgeois, an OpenAI spokesperson. "This partnership is consistent with our policies and does not involve leveraging our technology to develop systems designed to harm others," she said.

With his 2,141 SoundCloud followers, veteran U.K. psychedelic-music producer Darren Sangita didn't exactly wound Spotify when he pulled his music from the streaming service last month. "I'm a zed-list music celebrity," he says. But he couldn't support a company whose founder, Daniel Ek, invested more than $114 million in Helsing, a European security startup that manufactures artificial-intelligence software to "keep liberal democracies from harm." "The circumstantial evidence points to a massive investment in military/AI tech," says Sangita, who runs indie label Sangita Sounds. "I was just enormously disappointed. Are there not any other alternatives that Mr. Ek could have possibly thought about investing in to make the world a more beautiful and perhaps a safer place to live?"
