MLC LLM

Documentation | Blog | Discord

Machine Learning Compilation for Large Language Models (MLC LLM) is a high-performance universal deployment solution that allows native deployment of any large language models with native APIs with compiler acceleration. The mission of this project is to enable everyone to develop, optimize and deploy AI models natively on everyone's devices with ML compilation techniques.

Universal deployment. MLC LLM supports the following platforms and hardware:

	AMD GPU	NVIDIA GPU	Apple GPU	Intel GPU
Linux / Win	✅ Vulkan, ROCm	✅ Vulkan, CUDA	N/A	✅ Vulkan
macOS	✅ Metal (dGPU)	N/A	✅ Metal	✅ Metal (iGPU)
Web Browser	✅ WebGPU and WASM
iOS / iPadOS	✅ Metal on Apple A-series GPU
Android	✅ OpenCL on Adreno GPU		✅ OpenCL on Mali GPU

Scalable. MLC LLM scales universally on NVIDIA and AMD GPUs, cloud and gaming GPUs. Below showcases our single batch decoding performance with prefilling = 1 and decoding = 256.

Performance of 4-bit CodeLlama-34B and Llama2-70B on two NVIDIA RTX 4090 and two AMD Radeon 7900 XTX:

Scaling of fp16 and 4-bit CodeLlama-34 and Llama2-70B on A100-80G-PCIe and A10G-24G-PCIe, up to 8 GPUs:
