llama.cpp Release b11809 Adds WebGPU Q2_0 Support
llama.cpp release b11809 introduces WebGPU support for Q2_0 row dequantization and matrix multiplication. This update expands the capabilities of browser-based and web-accelerated large language model inference. Optimizing low-bit quantization formats like Q2_0 for WebGPU helps reduce memory footprints and accelerate inference times directly inside web browsers. This brings high-performance local AI capabilities closer to everyday web applications without requiring native installations. The release specifically implements row dequantization and matrix multiplication routines for the Q2_0 format running on the WebGPU backend. These kernels help mitigate performance bottlenecks for extremely compressed model weights.
## BACKGROUND
llama.cpp is an open-source software library that performs inference on various large language models using the GGML tensor library. WebGPU is a modern web standard designed to provide high-performance graphics and compute capabilities, such as running machine learning models, directly inside web browsers.
