# metaclip-2-worldwide-giant-378-lao-16384
This model is a **31.20% smaller** version of [facebook/metaclip-2-worldwide-giant-378](https://huggingface.co/facebook/metaclip-2-worldwide-giant-378) optimized for **Lao** language via vocabulary size reduction using the [trimming](https://huggingface.co/blog/lbourdois/introduction-to-trimming) method.  
This trimmed model should perform similarly to the original model with only 16,384 tokens and a much smaller memory footprint. However, it may not perform well for other languages as tokens not commonly used in the selected languages were removed from the vocabulary.

## Model Statistics
| Metric | Original | Trimmed | Reduction |
|--------|----------|---------|-----------|
| **Vocabulary size** | 901,629 tokens | 16,384 tokens | **98.18%** |
| **Model size** | 3,631,197,057 params | 2,498,083,457 params | **31.20%** |

## Usage

#### Transformers (zero-shot image classification)
```python
from transformers import pipeline

# load pipeline
image_classifier = pipeline(model="alphaedge-ai/metaclip-2-worldwide-giant-378-lao-16384", task="zero-shot-image-classification")

# load image and candidate labels
image = "http://images.cocodataset.org/val2017/000000039769.jpg"
candidate_labels = ["Potential label 1 in Lao", "Potential label 2 in Lao", "Potential label 3 in Lao", "Potential label 4 in Lao"]

# run inference
outputs = image_classifier(image, candidate_labels)
print(outputs)
```

#### Sentence-transformers (texts-images similarity)
```python
from sentence_transformers import SentenceTransformer

model = SentenceTransformer("alphaedge-ai/metaclip-2-worldwide-giant-378-lao-16384")

images = [
    "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/car.jpg",
    "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/bee.jpg",
    "https://huggingface.co/datasets/huggingface/cats-image/resolve/main/cats_image.jpeg"
]
texts = ["Text 1 in Lao", "Text 2 in Lao", "Text 3 in Lao", "Text 4 in Lao"]

image_embeddings = model.encode(images)
text_embeddings = model.encode(texts)
print(image_embeddings.shape, text_embeddings.shape)

similarities = model.similarity(image_embeddings, text_embeddings)
print(similarities)
```
