weight 3 · round drawnllama.cpp is a self-contained C/C++ inference engine designed to run models entirely locally via CLI or local server, with optimized backends for CPU, Apple Silicon, CUDA/AMD/Metal GPUs, and no external dependencies (gh-1,2,5,6,7,9,10). Extensive hands-on community reports confirm users running full inference pipelines (7B-70B models) entirely on their own Macs/PCs with no cloud calls, including offline vision workflows (comm-4,5,6,12,13,14,15). Missing for 10: no explicit first-party statement about data/privacy guarantees beyond the inherent local-only architecture.
