# Finetune Qwen3-Next with Axolotl
|
|
|
|
[Qwen3-Next](https://huggingface.co/collections/Qwen/qwen3-next-68c25fd6838e585db8eeea9d) represents the next-generation foundation models optimized for extreme context length and large-scale parameter efficiency. The series introduces architectural innovations including Hybrid Attention (Gated DeltaNet + Gated Attention), High-Sparsity MoE with 1:50 activation ratio, and Multi-Token Prediction for enhanced performance and inference acceleration.
|
|
|
|
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. Install FLA for improved performance
|
|
```bash
|
|
uv pip uninstall causal-conv1d && uv pip install flash-linear-attention==0.4.1
|
|
```
|
|
|
|
4. Run the finetuning example:
|
|
|
|
```bash
|
|
axolotl train examples/qwen3-next/qwen3-next-80b-a3b-qlora.yaml
|
|
```
|
|
|
|
This config uses about ~47 GiB (no target experts) and ~71GiB (target experts) VRAM.
|
|
|
|
Let us know how it goes. Happy finetuning! 🚀
|
|
|
|
### TIPS
|
|
|
|
- For inference, you can experiment with `temperature: 0.7`, `top_p: 0.8`, `top_k: 20`, and `min_p: 0`.
|
|
- You can run a full finetuning by removing the `adapter: qlora` and `load_in_4bit: true` from the config. See [Multi-GPU](#optimization-guides) section below.
|
|
- Read more on how to load your own dataset at [docs](https://docs.axolotl.ai/docs/dataset_loading.html).
|
|
- The dataset format follows the OpenAI Messages format as seen [here](https://docs.axolotl.ai/docs/dataset-formats/conversation.html#chat_template).
