The article introduces Unlimited OCR, a new approach to optical character recognition (OCR) that aims to improve performance by leveraging the prior distribution of language. This approach uses a large language model (LLM) as the decoder, allowing it to compensate for optical errors and artifacts. The model is designed to handle long-horizon parsing and can be used for various applications, including document parsing and data extraction. The article also provides implementation details and examples of how to use the model.
