China says its maglev hyperloop train has broken the world speed record in a test run, reaching a blistering 387 mph (623 km/h). Ultimately, its makers want to build a train more than three times as fast that will break the sound barrier and outpace airplanes. The maglev train, dubbed the T-Flight, was built by the state-owned China Aerospace Science and Industry Corporation (CASIC), New Atlas reported. Hyperloop trains work by pushing magnetically levitating pods through tunnels with very little air resistance.  The previous record holder for the fastest maglev train is the L0 Series SCMaglev in Japan, according to JRPass , which can hit a top speed of 375 mph (630 km/h). Related: Future electric cars could go more than 600 miles on a single charge thanks to battery-boosting gel To test the new train, CASIC built a track roughly 1.2 miles (2 kilometers) long in a low-pressure vacuum tube. To reach such high speeds, the trains must encounter almost no friction. So CASIC ...

OpenAI and its financial backer Microsoft were sued on Friday in Manhattan federal court by a pair of nonfiction authors who say the companies misused their work to train the artificial-intelligence models behind the popular chatbot ChatGPT and other AI-based services. Writers Nicholas Basbanes and Nicholas Gage told the court in a proposed class action that the companies infringed their copyrights by including several of their books as part of the data used to train OpenAI's GPT large language model. Representatives for Microsoft and OpenAI did not immediately respond to requests for comment on the complaint. The lawsuit follows several others filed by fiction and nonfiction writers ranging from comedian Sarah Silverman to " Game of Thrones" author George R.R. Martin against tech companies over the alleged use of their work to train AI programs. The New York Times also sued OpenAI and Microsoft last week over the use of its journalists...

NEW YORK: Meta Platforms' lawyers had warned it about the legal perils of using thousands of pirated books to train its AI models, but the company did it anyway, according to a new filing in a copyright infringement lawsuit initially brought this summer. The new filing late on Monday night consolidates two lawsuits brought against the Facebook and Instagram owner by comedian Sarah Silverman, Pulitzer Prize winner Michael Chabon and other prominent authors, who allege that Meta has used their works without permission to train its artificial-intelligence language model, Llama. A California judge last month dismissed part of the Silverman lawsuit and indicated that he would give the authors permission to amend their claims. Meta did not immediately respond to a request for comment on the allegations. The new complaint, filed on Monday, includes chat logs of a Meta-affiliated researcher discussing procurement of the dataset in a Discord server, a potentially sig...

A group of US authors, including Pulitzer Prize winner Michael Chabon, has sued OpenAI in federal court in San Francisco, accusing the Microsoft-backed program of misusing their writing to train its popular artificial intelligence-powered chatbot ChatGPT. Chabon, playwright David Henry Hwang and authors Matthew Klam, Rachel Louise Snyder and Ayelet Waldman said in their lawsuit on Friday that OpenAI copied their works without permission to teach ChatGPT to respond to human text prompts. Chabon's representatives referred queries about the lawsuit to the writers' lawyers. Those lawyers and representatives for OpenAI did not immediately respond to requests for comment on Monday. The lawsuit is at least the third proposed  copyright -infringement class action filed by authors against Microsoft-backed OpenAI. Companies, including Microsoft, Meta Platforms and Stability AI, have also been sued by copyright owners over the use of their work in AI...
