## Try with NeMo AutoModel

Install NeMo AutoModel and follow the fine-tuning guide to configure a recipe for this model.

**1. Install** ([full instructions](/get-started/installation)):

```bash
pip install nemo-automodel
```

**2. Clone the repo** to get example recipes you can adapt:

```bash
git clone https://github.com/NVIDIA-NeMo/Automodel.git
cd Automodel
```

**3. Fine-tune** using one of the provided MiniCPM5 recipes:

```bash
# Full fine-tuning
automodel examples/llm_finetune/minicpm/minicpm5_1b_squad.yaml --nproc-per-node 8

# LoRA fine-tuning
automodel examples/llm_finetune/minicpm/minicpm5_1b_squad_peft.yaml --nproc-per-node 8
```

**1. Pull the container** and mount a checkpoint directory:

```bash
docker run --gpus all -it --rm \
  --shm-size=8g \
  -v $(pwd)/checkpoints:/opt/Automodel/checkpoints \
  nvcr.io/nvidia/nemo-automodel:26.06.00
```

**2.** The recipes are at `/opt/Automodel/examples/` — navigate there:

```bash
cd /opt/Automodel
```

**3. Fine-tune**:

```bash
automodel --nproc-per-node=8 examples/llm_finetune/minicpm/minicpm5_1b_squad.yaml \
  --model.pretrained_model_name_or_path <MODEL_HF_ID>
```

Refer to the [Installation Guide](/get-started/installation) and [LLM Fine-Tuning Guide](/recipes-e2e-examples/sft-peft).
