What are ik_llama.cpp and Ollama?
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
Ollama
Ollama lets you download, run, and manage open large language models such as Llama, Mistral, Gemma, and Qwen on your own machine. It provides a simple command line interface and a built-in REST API so other tools can use local models.
- One-command model downloads
- OpenAI-compatible API
- GPU and CPU support
- Modelfile customization
