According to Paolo Ardoino, Tether AI has unveiled the QVAC Fabric LLM, integrating the world's first cross-platform BitNet LoRA framework. This innovation enables billion-parameter AI model training and inference on consumer GPUs and smartphones, utilizing Vulkan and Metal backends for AMD, Intel, Apple Metal, and mobile GPUs. By combining BitNet's efficient ternary weight compression with LoRA's parameter reduction, QVAC Fabric drastically reduces memory and compute requirements, achieving GPU inference speeds 2 to 11 times faster than CPU while using up to 90% less memory. This advancement signals a breakthrough in local, private AI accessible on consumer devices.
