r/LocalLLaMA: Developer Achieves 12 Tokens/Second on Android via Vulkan-Accelerated llama.cpp

A developer on r/LocalLLaMA published a writeup and code repository showing Vulkan-accelerated LLM inference running on a mid-range Android phone at 12 tokens per second with a quantized 7B model, requiring no root access or custom firmware. The project uses a modified llama.cpp backend that exposes Vulkan compute through Android's NDK, bypassing the typical requirement for a dedicated neural processing unit. The work is drawing interest from the edge AI community as a lower-cost path to offline inference on consumer hardware.
