# Finetune Magistral Small with Axolotl
|
|
|
|
Magistral Small is a 24B parameter opensource model from MistralAI found on HuggingFace at [2506](https://huggingface.co/mistralai/Magistral-Small-2506), [2507](https://huggingface.co/mistralai/Magistral-Small-2507) (see [Thinking](#thinking)), and [2509](https://huggingface.co/mistralai/Magistral-Small-2509) (see [Vision](#vision)). This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
|
|
|
|
MistralAI has also released a proprietary medium-sized version called Magistral Medium.
|
|
|
|
Thanks to the team at MistralAI for giving us early access to prepare for these releases.
|
|
|
|
## Getting started
|
|
|
|
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
|
|
|
|
Here is an example of how to install from pip:
|
|
|
|
```bash
|
|
# Ensure you have Pytorch installed (Pytorch 2.7.0 min)
|
|
uv pip install --no-build-isolation 'axolotl[flash-attn]>=0.12.0'
|
|
```
|
|
|
|
2. Install [Cut Cross Entropy](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy) to reduce training VRAM usage
|
|
|
|
```bash
|
|
python scripts/cutcrossentropy_install.py | sh
|
|
```
|
|
|
|
3. Run the finetuning example:
|
|
|
|
```bash
|
|
axolotl train examples/magistral/magistral-small-qlora.yaml
|
|
```
|
|
|
|
This config uses about 24GB VRAM.
|
|
|
|
Let us know how it goes. Happy finetuning! 🚀
|
|
|
|
### Thinking
|
|
|
|
MistralAI has released their [2507](https://huggingface.co/mistralai/Magistral-Small-2507) model with thinking capabilities, enabling Chain-of-Thought reasoning with explicit thinking steps.
|
|
|
|
📚 **[See the Thinking fine-tuning guide →](./think/README.md)**
|
|
|
|
### Vision
|
|
|
|
MistralAI has released their [2509](https://huggingface.co/mistralai/Magistral-Small-2509) model with vision capabilities.
|
|
|
|
📚 **[See the Vision fine-tuning guide →](./vision/README.md)**
|
|
|
|
### Tips
|
|
|
|
- We recommend adding the same/similar SystemPrompt that the model is tuned for. You can find this within the repo's files titled `SYSTEM_PROMPT.txt`.
|
|
- For inference, the official MistralAI team recommends `top_p: 0.95` and `temperature: 0.7` with `max_tokens: 40960`.
|
|
- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config.
|
|
- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
|
|
- The text dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).
|

## Optimization Guides

|
|
|
- [Multi-GPU Training](https://docs.axolotl.ai/docs/multi-gpu.html)
|
|
- [Multi-Node Training](https://docs.axolotl.ai/docs/multi-node.html)
|
|
- [LoRA Optimizations](https://docs.axolotl.ai/docs/lora_optims.html)
|
|
|
|
## Limitations
|
|
|
|
We only support the `mistral-common` tokenizer for Supervised Fine-tuning at the moment and for `type: chat_template` only.
|
|
|
|
In addition, we do not support overriding tokens yet.

## Future Work
|
|
|
|
- Add parity to Preference Tuning, RL, etc.
|
|
- Add parity to other tokenizer configs like overriding tokens.
