Identifying the Best OCR API: Benchmarking OCR APIs on Real-World Documents

With the rapid advancements in Large Language Models (LLMs) and Vision-Language Models (VLMs), many believe OCR has become obsolete. If LLMs can "see" and "read" documents, why not use them directly for text extraction?

The answer lies in reliability. Can you always be a 100% sure of the veracity of text output that LLMs interpret from a document/image? We put this to test with a simple experiment. We asked colleagues to use any LLM of their choice to extract a list of passenger names (10) from a sample PDF flight ticket.
