# CrystalChat-7B-MLLM: a fully-reproducible vision language model based on CrystalChat-7B

## Model Description

CrystalChat-7B based multi-modal large language model (MLLM) mimics the training recipe used for Vicuna-7B based [LLaVa-v1.5](https://huggingface.co./docs/transformers/main/model_doc/llava). CrystalChat-7B-MLLM models are entirely transparent, having open-sourced all materials, including code, data, model checkpoint, intermediate results, and more at [TODO: Add paper link]().

### About CrystalChat-7B-MLLM:
* 7 billion parameter LLM
* CLIP ViT-L/14-336px vision encoder
* Languages: English
* Models Released: CrystalChat-7B-MLLM
* Trained in 2 stages
* License: MIT

Crystal-based models were developed as a collaboration between [MBZUAI](https://mbzuai.ac.ae/institute-of-foundation-models/), [Petuum](https://www.petuum.com/), and [LLM360](https://www.llm360.ai/) TODO- check????.


## Evaluation

General Evaluation Metrics for MLLMs. MME serves as an extensive evaluative benchmark,
aiming to assess perceptual and cognitive capability of MLLMs within 14 sub-tasks. Additionally, we also evaluate the performance of our models on text-oriented visual question answering tasks employing a diverse set of benchmark datasets including ScienceQA and TextVQA. Furthermore, we assess our models’ ability toward anti-hallucination through POPE. 

| LLM Backbone                      | MME-P   | MME-C  | POPE  | SciQA  | TextVQA |
|-----------------------------------|---------|--------|-------|--------|---------|
| CrystalCoder-7B | 1359.83 | 238.92 | 86.18 | 64.15 | 50.39   |
| CrystalChat-7B  | 1456.53 | **308.21** | 86.96 | 67.77 | **57.84** |
| Vicuna-7B | **1481.12** | 302.85 | **87.17** | **67.97** | 56.49   |

## Data and Training Details

### Pretrain Data
LLaVA Visual Instruct Pretrain LCS-558K is a filtered subset of the LAION, CC, and SBU datasets, featuring a more balanced distribution of concept coverage. The file includes multimodal synthesized conversations generated from image-caption pairs by incorporating randomly selected instructions such as "Describe this image." It is used for pretraining in LLaVA, with the raw CC-3M caption serving as the default answer.

### Finetune Data

The dataset chosen was created by LLaVA with academic-task-oriented VQA data mixture and data from ShareGPT. LLaVA Visual Instruct 150K is a dataset of GPT-generated multimodal instruction-following data. It is designed for visual instruction tuning and aims to develop large multimodal models with capabilities akin to GPT-4 in both vision and language.

## LLM-360
LLM-360 is an open research lab enabling community-owned AGI through open-source large model research and development.

Crystal-based Models enables community-owned AGI by creating standards and tools to advance the bleeding edge of LLM capability and empower knowledge transfer, research, and development.

We believe in a future where artificial general intelligence (AGI) is created by the community, for the community. Through an open ecosystem of equitable computational resources, high-quality data, and flowing technical knowledge, we can ensure ethical AGI development and universal access for all innovators.
