# MetaCLIP 2

## Overview

MetaCLIP 2 is a replication of the original CLIP model trained on 300+ languages. It achieves state-of-the-art (SOTA) results on multilingual benchmarks (e.g., XM3600, CVQA, Babel‑ImageNet), surpassing previous SOTA such as [mSigLIP](siglip) and [SigLIP‑2](siglip2). The authors show that English and non-English worlds can mutually benefit and elevate each other.

This model was contributed by [nielsr](https://huggingface.co/nielsr).
The original code can be found [here](https://github.com/facebookresearch/MetaCLIP).

You can find all the MetaCLIP 2 checkpoints under the [Meta](https://huggingface.co/facebook/models?search=metaclip-2) organization.

> [!TIP]
> Click on the MetaCLIP 2 models in the right sidebar for more examples of how to apply MetaCLIP 2 to different image and language tasks.

The example below demonstrates how to calculate similarity scores between multiple text descriptions and an image with [Pipeline](/docs/transformers/v5.8.0/en/main_classes/pipelines#transformers.Pipeline) or the [AutoModel](/docs/transformers/v5.8.0/en/model_doc/auto#transformers.AutoModel) class. Usage of the MetaCLIP 2 models is identical to the CLIP models, you just need the `MetaClip2Model` class instead of `CLIPModel`.

```python
import torch

from transformers import pipeline

clip = pipeline(
   task="zero-shot-image-classification",
   model="facebook/metaclip-2-worldwide-huge-quickgelu",
   device=0
)
labels = ["a photo of a cat", "a photo of a dog", "a photo of a car"]
clip("http://images.cocodataset.org/val2017/000000039769.jpg", candidate_labels=labels)
```

```python
import requests
from PIL import Image

from transformers import AutoModel, AutoProcessor

model = AutoModel.from_pretrained("facebook/metaclip-2-worldwide-huge-quickgelu", attn_implementation="sdpa", device_map="auto")
processor = AutoProcessor.from_pretrained("facebook/metaclip-2-worldwide-huge-quickgelu")

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
labels = ["a photo of a cat", "a photo of a dog", "a photo of a car"]

inputs = processor(text=labels, images=image, return_tensors="pt", padding=True).to(model.device)

outputs = model(**inputs)
logits_per_image = outputs.logits_per_image
probs = logits_per_image.softmax(dim=1)
most_likely_idx = probs.argmax(dim=1).item()
most_likely_label = labels[most_likely_idx]
print(f"Most likely label: {most_likely_label} with probability: {probs[0][most_likely_idx].item():.3f}")
```

defaults will yield a similar configuration to that of the [facebook/metaclip-2-worldwide-huge-quickgelu](https://huggingface.co/facebook/metaclip-2-worldwide-huge-quickgelu)

Configuration objects inherit from [PreTrainedConfig](/docs/transformers/v5.8.0/en/main_classes/configuration#transformers.PreTrainedConfig) and can be used to control the model outputs. Read the

**Parameters:**

config ([MetaClip2Config](/docs/transformers/v5.8.0/en/model_doc/metaclip_2#transformers.MetaClip2Config)) : Model configuration class with all the parameters of the model. Initializing with a config file does not load the weights associated with the model, only the configuration. Check out the [from_pretrained()](/docs/transformers/v5.8.0/en/main_classes/model#transformers.PreTrainedModel.from_pretrained) method to load the model weights.

**Returns:**

`[ImageClassifierOutput](/docs/transformers/v5.8.0/en/main_classes/output#transformers.modeling_outputs.ImageClassifierOutput) or `tuple(torch.FloatTensor)``

A [ImageClassifierOutput](/docs/transformers/v5.8.0/en/main_classes/output#transformers.modeling_outputs.ImageClassifierOutput) or a tuple of
`torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various
elements depending on the configuration ([MetaClip2Config](/docs/transformers/v5.8.0/en/model_doc/metaclip_2#transformers.MetaClip2Config)) and inputs.
