## Vintern-3B-beta ❄️ - The LLaVA 🌋 Challenger

**What's new in Vintern-3B-beta!**
- **We successfully reproduced the training process of InternVL from scratch.**
- The model is the result of integrating [Qwen/Qwen2.5-3B-Instruct](https://huggingface.co/Qwen/Qwen2.5-3B-Instruct) and [InternViT-300M-448px](https://huggingface.co/OpenGVLab/InternViT-300M-448px) through an MLP layer.
- Trained with more than 10 Milion Vietnamese QnAs, Descriptions, and 10% English Data from [OpenGVLab/InternVL-Chat-V1-2-SFT-Data](https://huggingface.co/datasets/OpenGVLab/InternVL-Chat-V1-2-SFT-Data).

## Bytedance/MTVQA Benchmark

We surpassed GPT-4o and are approaching Gemini 1.5 Pro on the MTVQA dataset for Vietnamese.
The benchmark result in [MTVQA](https://github.com/bytedance/MTVQA/tree/main) from [open_vlm_leaderboard](https://huggingface.co/spaces/opencompass/open_vlm_leaderboard).

## OpenCompass Benchmark

We are creating a pull request for the OpenCompass team to test once more and make the metrics public on the [open_vlm_leaderboard](https://huggingface.co/spaces/opencompass/open_vlm_leaderboard).

The current results are at a quite good level, and we are expanding the training set in English and other languages to approach models within a comparable parameter range.

"The table is referenced from the repo [Qwen/Qwen2-VL-2B-Instruct](https://huggingface.co/Qwen/Qwen2-VL-2B-Instruct)."

## Quickstart

Here provides a code snippet to show you how to load the tokenizer and model and how to generate contents.
To run inference using the model, follow the steps outlined in our Colab inference notebook

```python

# from decord import VideoReader, cpu
from PIL import Image
from torchvision.transforms.functional import InterpolationMode

def build_transform(input_size):
    MEAN, STD = IMAGENET_MEAN, IMAGENET_STD
    transform = T.Compose([
        T.Lambda(lambda img: img.convert('RGB') if img.mode != 'RGB' else img),
        T.Resize((input_size, input_size), interpolation=InterpolationMode.BICUBIC),
        T.ToTensor(),
        T.Normalize(mean=MEAN, std=STD)
    ])
    return transform
