ColPali Cookbooks 👨🏻‍🍳

[ColPali Engine] [ViDoRe Benchmark]

Introduction

With our new model ColPali, we propose to leverage VLMs to construct efficient multi-vector embeddings in the visual space for document retrieval. By feeding the ViT output patches from PaliGemma-3B to a linear projection, we create a multi-vector representation of documents. We train the model to maximize the similarity between these document embeddings and the query embeddings, following the ColBERT method.

Using ColPali removes the need for potentially complex and brittle layout recognition and OCR pipelines with a single model that can take into account both the textual and visual content (layout, charts, ...) of a document.

This repository contains notebooks for learning, fine-tuning, and adapting ColPali to your multimodal RAG use cases.
