+# How To Export a LLM Model
+
+## Introduction
+
+In this guide you will learn how to export a [Large Language Model (LLM)](https://www.hopsworks.ai/dictionary/llms-large-language-models) and register it in the Model Registry.
+
+## Code
+
+### Step 1: Connect to Hopsworks
+
+=== "Python"
+    ```python
+    import hopsworks
+
+    project = hopsworks.login()
+
+    # get Hopsworks Model Registry handle
+    mr = project.get_model_registry()
+    ```
+
+### Step 2: Download the LLM
+
+Download your base or fine-tuned LLM. LLMs can typically be downloaded using the official frameworks provided by their creators (e.g., HuggingFace, Ollama, ...)
+
+=== "Python"
+    ```python
+    # Download LLM (e.g., using huggingface to download Llama-3.1-8B base model)
+    from huggingface_hub import snapshot_download
+
+    model_dir = snapshot_download(
+                    "meta-llama/Llama-3.1-8B",
+                    ignore_patterns="original/*"
+                )
+    ```
+
+### Step 3: (Optional) Fine-tune LLM
+
+If necessary, fine-tune your LLM with an [instruction set](https://www.hopsworks.ai/dictionary/instruction-datasets-for-fine-tuning-llms). A LLM can be fine-tuned fully or using [Parameter Efficient Fine Tuning (PEFT)](https://www.hopsworks.ai/dictionary/parameter-efficient-fine-tuning-of-llms) methods such as LoRA or QLoRA.
+
+=== "Python"
+    ```python
+    # Fine-tune LLM using PEFT (LoRA, QLoRA) or other methods
+    model_dir = ...
+    ```
+
+### Step 4: Register model in registry
+
+Use the `ModelRegistry.llm.create_model(..)` function to register a model as LLM. Define a name, and attach optional metrics for your model, then invoke the `save()` function with the parameter being the path to the local directory where the model was exported to.
+
+=== "Python"
+    ```python
+    # Model evaluation metrics
+    metrics = {'f1-score': 0.8, 'perplexity': 31.62, 'bleu-score': 0.73}
+
+    llm_model = mr.llm.create_model("llm_model", metrics=metrics)
+
+    llm_model.save(model_dir)
+    ```
+
+## Going Further
+
+You can attach an [Input Example](../input_example.md) and a [Model Schema](../input_example.md) to your model to document the shape and type of the data the model was trained on.

-import hopsworks
+=== "Python"
+    ```python

 ### Step 2: Train
 
 Define your XGBoost model and run the training loop.
 
-```python
-# Define a model
-model = XGBClassifier()
+=== "Python"
+    ```python
+    # Define a model
+    model = XGBClassifier()
 
-# Train model
-model.fit(X_train, y_train)
-
-```
+    # Train model
+    model.fit(X_train, y_train)
+    ```
 
 ### Step 3: Export to local path
 
 Export the XGBoost model to a directory on the local filesystem.
 
-```python
-
-model_file = "model.json"

+    model.save_model(model_file)
+    ```
 
 ### Step 4: Register model in registry
 
 Use the `ModelRegistry.python.create_model(..)` function to register a model as a Python model. Define a name, and attach optional metrics for your model, then invoke the `save()` function with the parameter being the path to the local directory where the model was exported to.
 
-```python
-
-# Model evaluation metrics
-metrics = {'accuracy': 0.92}
-
-py_model = mr.python.create_model("py_model", metrics=metrics)
+=== "Python"
+    ```python
+    # Model evaluation metrics
+    metrics = {'accuracy': 0.92}

-                                   input_example=input_example)
