# mlx-tune vs SimpleTuner

*GraphCanon updated Aug 23, 2026*

## Verdict

Pick mlx-tune if mlx-tune targets Mac users with Apple Silicon for fine-tuning LLMs across SFT, RLHP, GRPO, vision, TTS, STT, embeddings, and OCR using tools compatible with the UnSloth API; pick SimpleTuner if simpleTuner is a Python-based tool for fine-tuning diffusion models used in machine learning tasks such as image, video, and audio processing. It offers utilities and scripts to.

## Choose when

### Choose mlx-tune if…

- License: mlx-tune is Apache-2.0, SimpleTuner is AGPL-3.0.
- Tags unique to mlx-tune: apple-silicon, deep-learning, huggingface, large language models.
- Also covers LLM Frameworks, Speech & Audio.
- You need to fine-tune large language models on a Mac with Apple Silicon hardware

### Choose SimpleTuner if…

- License: SimpleTuner is AGPL-3.0, mlx-tune is Apache-2.0.
- Requirements: SimpleTuner does not have a stated requirement for Docker, making deployment more flexible..
- Tags unique to SimpleTuner: diffusers, diffusion-models, fine-tuning, flux-dev.
- SimpleTuner ships Docker support for self-hosted deployment.
- Use SimpleTuner when you need specialized fine-tuning capabilities for diffusion models involving image, video, or audio data.

## When NOT to use mlx-tune

- Your development environment is not based on macOS running on Apple Silicon
- The specific tasks you are targeting do not align with the capabilities of mlx-tune such as those exclusive to alternative platforms or tools

## When NOT to use SimpleTuner

- Do not use SimpleTuner if your project requires proprietary licensing, since it is released under AGPL-3.0 which may impose conditions that could be incompatible with commercial projects.
- Avoid SimpleTuner for tasks unrelated to diffusion models such as natural language processing, as it was designed specifically for image, video, and audio data.
