# Model Card: ReT-2

Official implementation of ReT-2: Recurrence Meets Transformers for Universal Multimodal Retrieval.

This model features a visual backbone based on [openai/clip-vit-large-patch14](https://huggingface.co/openai/clip-vit-large-patch14) and a textual backbone based on [colbert-ir/colbertv2.0](https://huggingface.co/colbert-ir/colbertv2.0). 
<br>The backbones have been fine-tuned on the M2KR dataset.
