Latest version:: 1.124.2 (31 Oct 2026)

Official site:: github.com
Licence:: Open source — AGPL-3.0 (bundled GGML/llama.cpp components under MIT)

Our verdict

KoboldCpp packs a llama.cpp-based model runner and the KoboldAI Lite interface into one executable you just double-click, which makes it one of the easiest ways to run GGUF models on Windows. It goes well beyond chat, with story-writing tools, image generation, speech and APIs that mimic OpenAI, Ollama and others. The interface is dense and aimed at hobbyists, and Intel Macs need a source build.

FAQ

Which KoboldCpp file should I pick?

On Windows, koboldcpp.exe is the NVIDIA (CUDA) build, koboldcpp-nocuda.exe is smaller and suits other GPUs via Vulkan, and koboldcpp-oldpc.exe targets older CPUs and GPUs. Linux has matching builds, and koboldcpp-mac-arm64 is for M-series Macs.

Is koboldcpp.com the official site?

No. The project's README warns that koboldcpp.com is a phishing site. Download only from the official GitHub releases page.
