Why You Should Not Use LLMs as OCR
Large language models are great at understanding and generating text. That does not mean they are good at reading documents.
A common mistake is treating LLMs like OCR systems, especially when dealing with scanned PDFs, tables, forms, or complex layouts. Instead of actually recognizing characters, LLMs rely on language prediction. That works fine for clean text but quickly falls apart with noisy scans, mixed formatting, or dense documents.
This blog breaks down why LLMs struggle with OCR style tasks, what really happens under the hood when you try to use them this way, and how traditional OCR still plays a critical role in document workflows. It also explains when combining OCR with LLMs actually makes sense instead of forcing one tool to do everything.
If you work with AI, automation, or document processing, this is a useful reminder that tool choice matters more than hype.
