Researchers found that DharmaOCR outperformed newer OCR models (Mistral OCR4 and Unlimited-OCR) on Brazilian Portuguese due to domain specialization and targeted training, where all model parameters were dedicated to the specific task of recognizing Brazilian Portuguese text. This approach enables the model to concentrate its resources on the target language, resulting in a structural advantage over multilingual models. The advantage of specialization does not depend on the model's architecture or training procedure, but rather on the direction of its resources. AI summary
