MLX

Quickstart|Installation| Documentation| Examples

MLX is an array framework for machine learning on Apple silicon, brought to you by Apple machine learning research.

Some key features of MLX include:

• Familiar APIs:MLX has a Python API that closely follows NumPy. MLX also has fully featured C++,C,and SwiftAPIs, which closely mirror the Python API. MLX has higher-level packages likemlx.nnand mlx.optimizerswith APIs that closely follow PyTorch to simplify building more complex models.

• Composable function transformations:MLX supports composable function transformations for automatic differentiation, automatic vectorization, and computation graph optimization.

• Lazy computation:Computations in MLX are lazy. Arrays are only materialized when needed.

• Dynamic graph construction:Computation graphs in MLX are constructed dynamically. Changing the shapes of function arguments does not trigger slow compilations, and debugging is simple and intuitive.

• Multi-device:Operations can run on any of the supported devices (currently the CPU and the GPU).

• Unified memory:A notable difference from MLX and other frameworks is theunified memory model.Arrays in MLX live in shared memory. Operations on MLX arrays can be performed on any of the supported device types without transferring data.

MLX is designed by machine learning researchers for machine learning researchers. The framework is intended to be user-friendly, but still efficient to train and deploy models. The design of the framework itself is also conceptually simple. We intend to make it easy for researchers to extend and improve MLX with the goal of quickly exploring new ideas.

The design of MLX is inspired by frameworks like NumPy, PyTorch,Jax,and ArrayFire.

Examples

TheMLX examples repohas a variety of examples, including:

• Transformer language modeltraining.
• Large-scale text generation with LLaMAand finetuning withLoRA.
• Generating images withStable Diffusion.
• Speech recognition withOpenAI's Whisper.
