What are ik_llama.cpp and llama.cpp?
ik_llama.cpp
ik_llama.cpp is a fork of llama.cpp maintained by ikawrakow that adds optimized CPU and CUDA kernels, additional quantization formats, and improved performance for mixture-of-experts models. It targets users running large local models on commodity hardware.
- New quantization types
- Optimized MoE inference
- CPU and CUDA kernels
- OpenAI-compatible server
llama.cpp
llama.cpp is a C/C++ inference engine for running LLaMA-family and many other models efficiently on CPUs and GPUs. It pioneered the GGUF quantized model format and powers a large portion of the local-AI ecosystem.
- GGUF quantization
- Runs on modest hardware
- Built-in HTTP server
- Broad GPU backend support
