Wu Blockchain has learned that Tether CEO Paolo Ardoino unveiled the new version of Tether AI team's QVAC Fabric, claiming it introduces the world's first cross-platform BitNet LoRA framework. Built on Vulkan and Apple Metal backends, it supports AMD, Intel, Apple, and mobile GPUs, enabling BitNet's LoRA fine-tuning and inference to run across GPU vendors and operating systems. He stated that the team has demonstrated fine-tuning of models with up to 3.8 billion parameters on devices like Pixel 9, S25, and iPhone 16, and can fine-tune models with 13 billion parameters on iPhone 16. GPU inference on mobile devices is 2–11 times faster than CPU inference, with memory usage reduced by up to 90%. https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=58247
