### 2. Creating the Visual Component GGUF
To create the GGUF for the visual components, we need to write a config for the visual encoder; make sure the config contains the correct `image_grid_pinpoints`
Next, create a new directory to hold the visual components, and copy the llava.clip/projector files, as shown below.
```bash
$ ENCODER_PATH=$PWD/visual_encoder
$ mkdir $ENCODER_PATH
$ cp $GRANITE_MODEL/llava.clip $ENCODER_PATH/pytorch_model.bin
$ cp $GRANITE_MODEL/llava.projector $ENCODER_PATH/
```
Now, we need to write a config for the visual encoder. In order to convert the model, be sure to use the correct `image_grid_pinpoints`, as these may vary based on the model. You can find the `image_grid_pinpoints` in `$GRANITE_MODEL/config.json`.
Note: we refer to this file as `$VISION_CONFIG` later on.

Now convert the components to GGUF; Note that we also override the image mean/std dev to `[.5,.5,.5]` since we use the siglip visual encoder - in the transformers model, you can find these numbers in the [preprocessor_config.json](https://huggingface.co/ibm-granite/granite-vision-3.1-2b-preview/blob/main/preprocessor_config.json).

### 3. Creating the LLM GGUF.
The granite vision model contains a granite LLM as its language model. For now, the easiest way to get the GGUF for LLM is by loading the composite model in `transformers` and exporting the LLM so that it can be directly converted with the normal conversion path.
First, set the `LLM_EXPORT_PATH` to the path to export the `transformers` LLM to.

```bash
$ export LLM_EXPORT_PATH=$PWD/granite_vision_llm

### 4. Running the Model in Llama cpp
Build llama cpp normally; you should have a target binary named `llama-llava-cli`, which you can pass two binaries to. Sample usage:
### 4. Quantization
If you want to quantize the LLM, you can do so with `llama-quantize` as you would any other LLM. For example:
```bash
$ ./build/bin/llama-quantize $LLM_EXPORT_PATH/granite_llm.gguf $LLM_EXPORT_PATH/granite_llm_q4_k_m.gguf Q4_K_M
$ LLM_GGUF_PATH=$LLM_EXPORT_PATH/granite_llm_q4_k_m.gguf
```

Note that currently you cannot quantize the visual encoder because granite vision models use SigLIP as the visual encoder, which has tensor dimensions that are not divisible by 32.
### 5. Running the Model in Llama cpp
Build llama cpp normally; you should have a target binary named `llama-llava-cli`, which you can pass two binaries to. As an example, we pass the the llama.cpp banner.
```bash
$ ./build/bin/llama-llava-cli -m $LLM_GGUF_PATH \
