Hugging Face Researchers Warn AI-Generated Video Consumes Much More Power Than Expected

1 month ago
"Researchers have found that the carbon footprint of generative AI-based tools that can turn text prompts into images and videos is far worse than we previously thought," writes Futurism: As detailed in a new paper, researchers from the open-source AI platform Hugging Face found that the energy demands of text-to-video generators quadruple when the length of a generated video doubles — indicating that the power required for increasingly sophisticated generations doesn't scale linearly. For instance, a six-second AI video clip consumes four times as much energy as a three-second clip. "These findings highlight both the structural inefficiency of current video diffusion pipelines and the urgent need for efficiency-oriented design," the researchers concluded in their paper... Fortunately, there are ways to slim down those demands, including intelligent caching, the reusing of existing AI generations, and "pruning," meaning the sifting out of inefficient examples from training datasets. The Hugging Face researchers gave their paper a cheeky title. "Video Killed the Energy Budget: Characterizing the Latency and Power Regimes of Open Text-to-Video Mode."

BYD's All-Electric Hypercar Hits 308 MPH, Becomes Fastest Car in Production

1 month ago
Electric powertrains allow for "crazy fast acceleration figures," reports Car and Driver, as well as "huge power numbers." And now a Chinese luxury electric car brand owned by BYD Auto "just hit a top speed of 308.4 mph, making it not only the fastest electric car on the planet, but the fastest car. Period." Engadget reports that the U9 Xtreme "is packed with four motors that produce just under 3,000 horsepower. The electric hypercar also runs on one of the world's first 1,200V platforms, which offers better performance and efficiency, along with some weight reduction." And Car and Driver adds that "Other changes to achieve the speed include dropping the wheel size from 21 to 20 inches, narrowing the front track, and adding wider, semi-slick track tires at the front of the car." One small caveat that doesn't lessen the impressiveness of the feat is that while the U9 Xtreme does classify as a production model, it barely does. That's because BYD is planning to limit production of the top-speed version of the U9 to no more than 30 units. The car hit its "facemelting" top speed during a livestream at Germany's Automotive Testing Papenburg, reports Engadget. Thanks to long-time Slashdot reader hackingbear for sharing the news.
