# Granite Vision
|
|||
|
|
|
|||
|
|
## Overview
|
|||
|
|
|
|||
|
|
The [Granite Vision](https://www.ibm.com/new/announcements/ibm-granite-3-1-powerful-performance-long-context-and-more) model is a variant of [LLaVA-NeXT](llava_next), leveraging a [Granite](granite) language model alongside a [SigLIP](SigLIP) visual encoder. It utilizes multiple concatenated vision hidden states as its image features, similar to [VipLlava](vipllava). It also uses a larger set of image grid pinpoints than the original LlaVa-NeXT models to support additional aspect ratios.
|
|||
|
|
|
|||
|
|
Tips:
|
|||
|
|
- This model is loaded into Transformers as an instance of LlaVA-Next. The usage and tips from [LLaVA-NeXT](llava_next) apply to this model as well.
|
|||
|
|
|
|||
|
|
- You can apply the chat template on the tokenizer / processor in the same way as well. Example chat format:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
"<|user|>\nWhat’s shown in this image?\n<|assistant|>\nThis image shows a red stop sign.<|end_of_text|><|user|>\nDescribe the image in more details.\n<|assistant|>\n"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Sample inference:
|
|||
|
|
|
|||
|
|
```python
|
|||
|
|
from transformers import LlavaNextProcessor, LlavaNextForConditionalGeneration, infer_device
|
|||
|
|
|
|||
|
|
device = infer_device()
|
|||
|
|
|
|||
|
|
model_path = "ibm-granite/granite-vision-3.1-2b-preview"
|
|||
|
|
processor = LlavaNextProcessor.from_pretrained(model_path)
|
|||
|
|
|
|||
|
|
model = LlavaNextForConditionalGeneration.from_pretrained(model_path).to(device)
|
|||
|
|
|
