mlx-tune: Fine-Tune LLMs on Apple Silicon with SFT, DPO, GRPO, Vision via Unsloth-Compatible API
r/LocalLLaMA·low signal
mlx-tune is a new open-source library for fine-tuning LLMs natively on Apple Silicon using MLX, supporting SFT, DPO, GRPO, and vision modalities with an API compatible with Unsloth workflows. Built by a practitioner who runs Unsloth on cloud GPUs daily but wanted a local Mac equivalent without cloud costs. Meaningful for developers who want to fine-tune models locally without a dedicated GPU rig.
