Overview
Fast LLM inference in C/C++ for local deployment
Pros
- โ Runs 4-bit quantized LLMs on CPU-only machines
- โ Optimized for Apple Silicon via Metal; supports CUDA and Vulkan
- โ Provides an OpenAI-compatible server mode (llama-server)
- โ Foundation of Ollama and LM Studio โ battle-tested at scale
Cons
- โ C++ codebase requires compilation from source for some platforms
- โ Quantization reduces quality compared to full-precision models
Key Features
- โข {'icon': 'โก', 'title': '4-bit Quantization on CPU', 'desc': 'Run large language models on standard CPU-only machines with 4-bit quantization, reducing memory footprint by up to 75% without requiring GPU hardware.'}
- โข {'icon': '๐', 'title': 'Apple Silicon Acceleration', 'desc': 'Native Metal acceleration for M1/M2/M3 chips enables 2-3x faster inference compared to CPU-only, plus CUDA and Vulkan support for cross-platform deployment.'}
- โข {'icon': '๐', 'title': 'OpenAI-Compatible API Server', 'desc': 'llama-server provides drop-in OpenAI API compatibility, allowing existing applications to switch from cloud APIs to local inference with zero code changes.'}
- โข {'icon': '๐ฆ', 'title': 'Minimal Dependencies', 'desc': 'Pure C/C++ implementation with no Python runtime or framework dependencies; single binary deployment across Linux, macOS, Windows, and embedded systems.'}
- โข {'icon': '๐ฏ', 'title': 'Real-time Token Streaming', 'desc': 'Streaming token output via HTTP Server-Sent Events enables responsive chat interfaces and real-time text generation on local hardware.'}
