ECLAIR

ECLAIR is a general purpose text-extraction model, specifically designed to handle documents. Given an image, ECLAIR is able to extract formatted-text, with bounding-boxes and the corresponding semantic class. This has downstream benefits for several tasks such as increasing the availability of training-data for Large Language Models (LLMs), improving the accuracy of retriever systems, and enhancing document understanding pipelines.

This model is for demonstration purposes and it is not for production usage.
