# Finetune MoonshotAI's Kimi Linear with Axolotl
[Kimi Linear](https://huggingface.co/collections/moonshotai/kimi-linear-a3b) is a MoE model (48B total, 3B active) by MoonshotAI using a hybrid linear attention architecture to achieve a 1M token context length. It uses Kimi Delta Attention (KDA), a refined version of Gated DeltaNet that reduces KV cache size by up to 75% and boosts decoding throughput by up to 6x for long contexts.
This guide shows how to fine-tune it with Axolotl with multi-turn conversations and proper masking.
**Note:** Axolotl uses experimental training code for Kimi Linear as their original modeling code is inference-only.
## Getting started
1. Install Axolotl following the [installation guide](https://docs.axolotl.ai/docs/installation.html).
2. Install CCE via [docs](https://docs.axolotl.ai/docs/custom_integrations.html#cut-cross-entropy)
3. Run the finetuning example:
```bash
axolotl train examples/kimi-linear/kimi-48b-lora.yaml
```
This config uses about 98.7GiB VRAM.
Let us know how it goes. Happy finetuning!
### TIPS
- Kimi Linear requires `trust_remote_code: true`.
- You can run a full finetuning by removing the `adapter: lora` and `load_in_8bit: true`.
- 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)
## Optimization Guides
See 👉 [docs](https://docs.axolotl.ai/docs/optimizations.html).
## Limitations
This is not yet compatible with MoE kernels from transformers v5.
