The notebook demonstrates how Vision Language Models (VLMs) like Donut and Pix2Struct can extract structured data from document images, surpassing traditional OCR in accuracy and handling complex layouts. Instead of relying on OCR's text extraction and post-processing, VLMs directly interpret the image and output the desired data in a structured format like JSON, simplifying downstream tasks. This approach proves especially effective for invoices, receipts, and forms where specific information needs to be extracted and organized. The examples showcase how to define the desired output structure using prompts and how VLMs effectively handle various document layouts and complexities, eliminating the need for complex OCR pipelines and post-processing logic.
HN users generally expressed excitement about the potential of Vision-Language Models (VLMs) to replace OCR, finding the demo impressive. Some highlighted VLMs' ability to understand context and structure, going beyond mere text extraction to infer meaning and relationships within a document. However, others cautioned against prematurely declaring OCR obsolete, pointing out potential limitations of VLMs like hallucinations, difficulty with complex layouts, and the need for robust evaluation beyond cherry-picked examples. The cost and speed of VLMs compared to mature OCR solutions were also raised as concerns. Several commenters discussed specific use-cases and potential applications, including data entry automation, accessibility for visually impaired users, and historical document analysis. There was also interest in comparing different VLMs and exploring fine-tuning possibilities.
OlmOCR is a free and open-source tool designed for extracting text from PDF documents, especially those with complex layouts or scanned images.

One commenter suggested potential integration with other tools and platforms to broaden its accessibility.
The blog post benchmarks Vision-Language Models (VLMs) against traditional Optical Character Recognition (OCR) engines for complex document understanding tasks. It finds that while traditional OCR excels at simple text extraction from clean documents, VLMs demonstrate superior performance on more challenging scenarios, such as understanding the layout and structure of complex documents, handling noisy or low-quality images, and accurately extracting information from visually rich elements like tables and forms. This suggests VLMs are better suited for real-world document processing tasks that go beyond basic text extraction and require a deeper understanding of the document's content and context.
Hacker News users discussed potential biases in the OCR benchmark, noting the limited scope of document types and languages tested. Some questioned the methodology, suggesting the need for more diverse and realistic datasets, including noisy or low-quality scans.
