Baidu’s ‘Unlimited OCR’ can process dozens of document pages at once, revolutionizing text recognition. By treating memory like human forgetting, the model keeps memory use and speed constant, regardless of text length. This is achieved through a redesigned attention mechanism that mimics human behavior, allowing the model to focus on the most recent information. Why it matters: this innovation has significant implications for the development of more efficient and scalable AI models, particularly in industries that rely heavily on document processing.
