MLX Swift Examples

Example MLX Swift programs.

• MNISTTrainer: An example that runs on both iOS and macOS that downloads MNIST training data and trains a LeNet.

• LLMEval: An example that runs on both iOS and macOS that downloads an LLM and tokenizer from Hugging Face and generates text from a given prompt.

• LinearModelTraining: An example that trains a simple linear model.

• StableDiffusionExample: An example that runs on both iOS and macOS that downloads a stable diffusion model from Hugging Face and and generates an image from a given prompt.

• llm-tool: A command line tool for generating text using a variety of LLMs available on the Hugging Face hub.

• image-tool: A command line tool for generating images using a stable diffusion model from Hugging Face.

• mnist-tool: A command line tool for training a a LeNet on MNIST.

Running

The application and command line tool examples can be run from Xcode or from the command line:

./mlx-run llm-tool --prompt "swift programming language"

Installation of MLXLLM and MLXMNIST libraries

The MLXLLM, MLXMNIST and StableDiffusion libraries in the example repo are available as Swift Packages.

Add the following dependency to your Package.swift

.package(url: "https://github.com/ml-explore/mlx-swift-examples/", branch: "main"),

Then add one library or both libraries to the target as a dependency.

.target(
    name: "YourTargetName",
    dependencies: [
        .product(name: "LLM", package: "mlx-swift-examples")
    ]),

Alternatively, add https://github.com/ml-explore/mlx-swift-examples/ to the Project Dependencies and set the Dependency Rule to Branch and main in Xcode.
