# Model Card for cerebras/Cerebras-LLaVA-7B
The checkpoints consists of Language encoder and projector weights of multimodal LLaVA-7B model trained with our Cerebras implementation and training recipe. 
The vision encoder checkpoints for this model can be found at [cerebras/Cerebras-ViT-L-336-patch14-llava7b-ShareGPT4V](https://huggingface.co/cerebras/Cerebras-ViT-L-336-patch14-llava7b-ShareGPT4V)

**Note**: _ShareGPT4V_ is added to the vision model name to ensure correct loading of checkpoints in [LLaVA source repo](https://github.com/haotian-liu/LLaVA/blob/main/llava/model/multimodal_encoder/builder.py#L8)

For full details of this model and training details, please read our upcoming blog post.

## Model Architecture
Cerebras-LLaVA-7B is a transformer model with the following architecture details
* Vision encoder: [CLIP-VisionModel-Large](cerebras/Cerebras-ViT-L-336-patch14-llava7b-ShareGPT4V). It handles images of size 336 x 336 with patch size of 14
* Large Language Model: Pretrained from Vicuna-7B checkpoints and instruction finetuned on various datasets.
* Projector: the projector module that connects the LLM and Vision encoder part consists of two linear layers with gelu activation (mlp2x-gelu)

## Loading the model
This model can directly be loaded using the [LLaVa source code repository](https://github.com/haotian-liu/LLaVA). For installation, please refer to the [instructions in source code repository](https://github.com/haotian-liu/LLaVA?tab=readme-ov-file#install).
We perform all our evaluations using the LLaVA source code repository scripts.

```
from llava.model.builder import load_pretrained_model
from llava.mm_utils import get_model_name_from_path
from llava.eval.run_llava import eval_model

model_path = "cerebras/Cerebras-LLaVA-7B"

tokenizer, model, image_processor, context_len = load_pretrained_model(
    model_path=model_path,
    model_base=None,
    model_name=get_model_name_from_path(model_path)
)
```

## Intended Use
_Primary intended uses_: The primary use of LLaVA is research on large multimodal models and chatbots.

_Primary intended users_: The primary intended users of the model are researchers(both academic and industry) in computer vision, natural language processing, machine learning, and artificial intelligence

## Limitations and Bias
The pre-training dataset may have contained offensive or inappropriate content, even after applying data cleansing filters, which can be reflected in the model-generated text. 
We recommend that users exercise caution when using these models for their applications or any use case that may cause deliberate or unintentional harm to others. This model is for demonstration purpose only.
