What are exo and ik_llama.cpp?
exo
exo is an open-source project that unifies multiple everyday devices into a single AI compute cluster for running large language models. It splits models across phones, laptops, and desktops and exposes an OpenAI-compatible API.
- Distributes models across devices
- OpenAI-compatible API
- Automatic device discovery
- No master node required
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
