# Finetune SmolVLM2 with Axolotl
[SmolVLM2](https://huggingface.co/collections/HuggingFaceTB/smolvlm2-smallest-video-lm-ever-67ab6b5e84bf8aaa60cb17c7) are a family of lightweight, open-source multimodal models from HuggingFace designed to analyze and understand video, image, and text content.
These models are built for efficiency, making them well-suited for on-device applications where computational resources are limited. Models are available in multiple sizes, including 2.2B, 500M, and 256M.
This guide shows how to fine-tune SmolVLM2 models with Axolotl.
## 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 a compatible version of Pytorch installed
uv pip install --no-build-isolation 'axolotl[flash-attn]>=0.12.0'
```
2. Install an extra dependency:
```bash
uv pip install num2words==0.5.14
```
3. Run the finetuning example:
```bash
# LoRA SFT (1x48GB @ 6.8GiB)
axolotl train examples/smolvlm2/smolvlm2-2B-lora.yaml
```
## TIPS
- **Dataset Format**: For video finetuning, your dataset must be compatible with the multi-content Messages format. For more details, see our documentation on [Multimodal Formats](https://docs.axolotl.ai/docs/multimodal.html#dataset-format).
- **Dataset Loading**: Read more on how to prepare and load your own datasets in our [documentation](https://docs.axolotl.ai/docs/dataset_loading.html).
## Optimization Guides
Please check the [Optimizations doc](https://docs.axolotl.ai/docs/optimizations.html).
