What are ik_llama.cpp and OpenLLM?
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
OpenLLM
OpenLLM lets developers run open-source large language models as OpenAI-compatible API endpoints with a single command. It is built on BentoML and supports streaming, quantization, and easy deployment.
- One-command model serving
- OpenAI-compatible API
- Built-in chat UI
- Cloud deployment via BentoML
