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.
Replicate is a platform for running AI models in the cloud with a simple API. It hosts thousands of open-source models including Llama, Stable Diffusion, and Whisper, letting developers run them with a single API call. Replicate handles GPU provisioning, scaling, and model optimization automatically.
