BitRun

BitRun is a single-binary runner and model manager for Microsoft BitNet b1.58 and ternary LLMs on CPU.

BitRun is a zero-compile, single-binary runner and model manager designed for Microsoft BitNet b1.58 and 1.58-bit ternary large language models on macOS, Windows, and Linux CPUs. It eliminates the need for managing C++ compilers, CMake, Python toolchains, or heavy Docker images by packaging the native inference engine into a single binary. The product features a Go supervisor layer and a native C++ engine tier utilizing ARM NEON and x86 AVX-512 kernels. It is built for developers wanting local CPU inference on battery-powered laptops and edge devices. Supported models include bitnet-70m, bitnet-2b, falcon3-1b, falcon3-3b, and llama3-8b, and it includes an OpenAI-compatible REST server.
