Decentralized compute infrastructure aggregating idle GPUs for low-cost inference.
llama.cpp is the foundational C/C++ inference engine for running LLMs locally. 107K+ GitHub stars. Supports GGUF format with 1.5-bit through 8-bit quantization, Apple Silicon (Metal/Accelerate), x86 (AVX/AMX), CUDA, ROCm, and MUSA — the backbone of nearly every local-LLM tool in the ecosystem.
Core capabilities each platform advertises.
