What are llama.cpp and MLC LLM?

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

MLC LLM

MLC LLM is a machine learning compiler and runtime that deploys language models natively across GPUs, CPUs, browsers, and mobile devices. It enables high-performance self-hosted inference on diverse hardware.

  • Compile models for any hardware
  • Native GPU acceleration
  • Browser and mobile runtimes
  • OpenAI-compatible serving
