# Finetune Ministral with Axolotl
|
|
|
|
Ministral is a family of openweight models from MistralAI found on HuggingFace at [2410](mistralai/Ministral-8B-Instruct-2410) and [2512](https://huggingface.co/collections/mistralai/ministral-3) (see [Thinking](#thinking)). This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
|
|
|
|
## Getting started
|
|
|
|
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
|
|
|
|
2. Install [Cut Cross Entropy](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy) to reduce training VRAM usage.
|
|
|
|
3. Run the finetuning example:
|
|
|
|
```bash
|
|
axolotl train examples/ministral/ministral-small-qlora.yaml
|
|
```
|
|
|
|
This config uses about 8.76 GiB VRAM.
|
|
|
|
Let us know how it goes. Happy finetuning! 🚀
|
|
|
|
### Thinking
|
|
|
|
MistralAI has released their [Ministral3 2512](https://huggingface.co/collections/mistralai/ministral-3) model with thinking capabilities, enabling Chain-of-Thought reasoning with explicit thinking steps.
|
|
|
|
📚 **[See the Thinking fine-tuning guide →](./think/README.md)**
|
|
|
|
For Ministral3 Base/Instruct, you can reuse the above config to train supervised finetuning.
|
|
|
|
### 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`.
|
|
- 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
|
|
|
|
Please check the [Optimizations doc](https://docs.axolotl.ai/docs/optimizations.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.
