# SmolVLM2-500M-Video

SmolVLM2-500M-Video is a lightweight multimodal model designed to analyze video content. The model processes videos, images, and text inputs to generate text outputs - whether answering questions about media files, comparing visual content, or transcribing text from images. Despite its compact size, requiring only 1.8GB of GPU RAM for video inference, it delivers robust performance on complex multimodal tasks. This efficiency makes it particularly well-suited for on-device applications where computational resources may be limited.
## Model Summary

- **Developed by:** Hugging Face 🤗
- **Model type:** Multi-modal model (image/multi-image/video/text)
- **Language(s) (NLP):** English
- **License:** Apache 2.0
- **Architecture:** Based on [Idefics3](https://huggingface.co/HuggingFaceM4/Idefics3-8B-Llama3) (see technical summary)

## Resources

- **Demo:** [Video Highlight Generator](https://huggingface.co/spaces/HuggingFaceTB/SmolVLM2-HighlightGenerator)
- **Blog:** [Blog post](https://huggingface.co/blog/smolvlm2)

## Uses

SmolVLM2 can be used for inference on multimodal (video / image / text) tasks where the input consists of text queries along with video or one or more images. Text and media files can be interleaved arbitrarily, enabling tasks like captioning, visual question answering, and storytelling based on visual content. The model does not support image or video generation.

To fine-tune SmolVLM2 on a specific task, you can follow [the fine-tuning tutorial](https://github.com/huggingface/smollm/blob/main/vision/finetuning/Smol_VLM_FT.ipynb).

## Evaluation 

We evaluated the performance of the SmolVLM2 family on the following scientific benchmarks:

| Size    | Video-MME | MLVU | MVBench |
|----------|-----------------|----------|---------------|
| 2.2B   | 52.1            | 55.2     | 46.27        |
| 500M | 42.2            | 47.3     | 39.73        |
| 256M | 33.7            | 40.6     | 32.7          |


### How to get started

You can use transformers to load, infer and fine-tune SmolVLM. Make sure you have num2words, flash-attn and latest transformers installed.
You can load the model as follows.

```python
from transformers import AutoProcessor, AutoModelForImageTextToText

model_path = "HuggingFaceTB/SmolVLM2-500M-Video-Instruct"
processor = AutoProcessor.from_pretrained(model_path)
model = AutoModelForImageTextToText.from_pretrained(
    model_path,
    torch_dtype=torch.bfloat16,
    _attn_implementation="flash_attention_2"
).to("cuda")
```

#### Simple Inference

You preprocess your inputs directly using chat templates and directly passing them 

```python
messages = [
    {
        "role": "user",
        "content": [
{"type": "text", "text": "What is in this image?"},
            {"type": "image", "path": "path_to_img.png"},
            
        ]
    },
]

inputs = processor.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device, dtype=torch.bfloat16)

generated_ids = model.generate(**inputs, do_sample=False, max_new_tokens=64)
generated_texts = processor.batch_decode(
    generated_ids,
    skip_special_tokens=True,
)
print(generated_texts[0])
```

#### Video Inference

To use SmolVLM2 for video inference, make sure you have decord installed. 

```python
messages = [
    {
        "role": "user",
        "content": [
            {"type": "video", "path": "path_to_video.mp4"},
            {"type": "text", "text": "Describe this video in detail"}
        ]
    },
]

inputs = processor.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device)

generated_ids = model.generate(**inputs, do_sample=False, max_new_tokens=64)
generated_texts = processor.batch_decode(
    generated_ids,
    skip_special_tokens=True,
)

print(generated_texts[0])
```
#### Multi-image Interleaved Inference

You can interleave multiple media with text using chat templates.

```python
import torch


messages = [
    {
        "role": "user",
        "content": [
{"type": "text", "text": "What is the similarity between this image <image>"},

            {"type": "image", "path": "image_1.png"},
{"type": "text", "text": "and this image <image>"},
{"type": "image", "path": "image_2.png"},            
        ]
    },
]
inputs = processor.apply_chat_template(
    messages,
    add_generation_prompt=True,
    tokenize=True,
    return_dict=True,
    return_tensors="pt",
).to(model.device)

generated_ids = model.generate(**inputs, do_sample=False, max_new_tokens=64)
generated_texts = processor.batch_decode(
    generated_ids,
    skip_special_tokens=True,
)
print(generated_texts[0])
```
