Built a macOS desktop UI around mlx-lm for data prep & fine-tuning (M-Courtyard)

[tuwenbo0120]

Hey everyone, huge thanks to the MLX team for the amazing framework.

I wanted to share a desktop tool I built called Courtyard. It leverages mlx-lm under the hood to provide an end-to-end local fine-tuning GUI for Apple Silicon.

Basically, it provides a UI for:

Formatting raw text into training datasets.
Running mlx-lm.lora with configurable hyperparameters (managing the MLX subprocesses).
Testing the generated adapters directly in a chat UI.
Exporting the fused models (supports Ollama integration).

I built this to scratch my own itch, but I figured the MLX community might find it useful. I’d really appreciate any feedback on how I’m handling the MLX subprocesses or if there are specific mlx-lm features I should expose in the UI next!
