# Goekdeniz-Guelmez/Josie-v6-2b-mlx-concept

## Overview

This is a crude proof of concept (PoC) demonstrating the feasibility of fine-tuning a large language model (LLM) on Apple Silicon using the MLX-LM framework. The goal is to explore the capabilities of Apple’s hardware for local LLM training and fine-tuning workflows.

## Model and Training Details

- **Base Model:** `mlx-community/helium-1-preview-2b`
- **Fine-Tuned Model:** `J.O.S.I.E.v6-2b`
- **Context length:** 4098
- **Trained number of Tokens:** ca. 1T
- **Created by:** Gökdeniz Gülmez
- **Fine-Tune Dataset:** Offline private dataset
- **DPO/ORPO Dataset:** Offline private dataset
- **Prompt Template:**

  ```text
  <|im_start|>system
  You are Josie my private, super-intelligent assistant.<|im_end|>
  <|im_start|>Gökdeniz Gülmez
  {{ .PROMPT }}<|im_end|>
  <|im_start|>Josie
  {{ .RESPONSE }}<|im_end|>
  ```

- **Training Process:**
  - First **10K steps** trained using **LoRA** (Low-Rank Adaptation) with **22 layers** selected.
  - Second **1K steps** trained using **full weight training**.
  - Final **4K steps** ORPO training using **DoRA** with **22 layers** selected.

## Hardware Used

- **Device:** Apple Mac Mini M4 (32GB RAM)
- **Framework:** Apple MLX-LM

## Quantisations

- [MLX 4 Bit](Goekdeniz-Guelmez/Josie-v6-2b-mlx-concept-4bit)
- [MLX 6 Bit](Goekdeniz-Guelmez/Josie-v6-2b-mlx-concept-6bit)
- [MLX 8 Bit](Goekdeniz-Guelmez/Josie-v6-2b-mlx-concept-8bit)

## Notes & Limitations

- This is an experimental setup; performance and efficiency optimizations are ongoing.
- Dataset details remain private and are not included in this repository.
- The training process may require significant memory and computational resources despite optimizations.
- Further work is needed to explore distributed training and mixed-precision techniques for better performance on Apple Silicon.

## ORPO Training

ORPO training is not yet available in the official `mlx-examples` repository. To use it, you will need to clone and work from my fork:
[https://github.com/Goekdeniz-Guelmez/mlx-examples.git](https://github.com/Goekdeniz-Guelmez/mlx-examples.git)

## Future Improvements

- Experiment with additional quantization techniques to reduce VRAM usage.
- Investigate performance scaling across multiple Apple Silicon devices.
- Optimize training pipelines for better convergence and efficiency.

## Community Feedback

I would love to hear from the MLX community! Should I publish a tutorial on how to fine-tune LLMs on Apple Silicon? If so, would you prefer it in text or video format? Let me know!

## Disclaimer

This project is strictly for research and experimental purposes. The fine-tuned model is not intended for production use at this stage.
