全新开源的DeepSeek-OCR，可能是最近最惊喜的模型。

Core Insights - The article discusses the introduction of DeepSeek-OCR, a new model that enhances traditional Optical Character Recognition (OCR) capabilities by not only extracting text but also generating structured documents and compressing information effectively [1][3][5]. Group 1: Traditional OCR vs. DeepSeek-OCR - Traditional OCR primarily converts images of text into editable digital text, which can be cumbersome for complex documents like financial reports [3][5]. - DeepSeek-OCR goes beyond traditional OCR by generating Markdown documents that maintain the structure of the original content, including text, titles, and charts, making it more versatile [5][6]. Group 2: Contextual Compression - DeepSeek-OCR introduces a novel approach called "Contextual Optical Compression," which allows the model to process long texts more efficiently by converting them into image files instead of tokenized text [18][19]. - This method significantly reduces the computational load associated with processing long texts, as the complexity of token processing increases quadratically with text length [8][10][11]. Group 3: Performance Metrics - The model achieves a remarkable compression ratio of up to 10 times while maintaining a recognition accuracy of 96.5% [23]. - The compression ratio is calculated by dividing the total number of original text tokens by the number of visual tokens after compression [24]. Group 4: Implications for AI and Memory - The article suggests that DeepSeek-OCR's approach mirrors human memory, where recent information is retained with high fidelity while older information gradually fades [39][40]. - This mechanism of "forgetting" is presented as a potential advantage for AI, allowing it to prioritize important information and manage memory more like humans do [40][41].
