# LLaVA-Gemma Model Card |
|
|
|
_This model card corresponds to the 2B version of the model with the CLIP-based vision encoder._ |
|
|
|
## Overview |
|
|
|
`llava-gemma-2b` is a large multimodal model (LMM) trained using the [LLaVA-v1.5 framework](https://arxiv.org/abs/2310.03744) with the 2-billion parameter `google/gemma-2b-it` model as language backbone. |
|
|
|
## Uses |
|
|
|
The model has been finetuned for multimodal benchmark evaluations, but can also be used as a multimodal chatbot. |
|
|
|
|
|
## Bias, Risks, and Limitations |
|
|
|
This model has not been assessed for harm or biases, and should not be used for sensitive applications where it may cause harm. |
|
|
|
|
|
## How to Get Started with the Model |
|
|
|
Using the LLaVA-Gemma models currently requires a custom fork of the [`LLaVA`](https://github.com/haotian-liu/LLaVA) library. _We will release converted checkpoints compatible with the HuggingFace implementation of LLaVA shortly._ |
|
|
|
|
|
|
|
|
|
## Training Details |
|
|
|
The `llava-gemma-2b` model was trained on 8 Gaudi 2 accelerators. |
|
|
|
|
|
### Training Data |
|
|
|
The model was trained using the LLaVA-v1.5 data mixture. |
|
|
|
This is listed as follows: |
|
|
|
- 558K filtered image-text pairs from LAION/CC/SBU, captioned by BLIP. |
|
- 158K GPT-generated multimodal instruction-following data. |
|
- 450K academic-task-oriented VQA data mixture. |
|
- 40K ShareGPT data. |
|
