[cost\_intel] When does GPT-4o Vision become cheaper than dedicated OCR APIs for document extraction?

Use GPT-4o Vision for document OCR only when documents contain complex layouts \(tables, handwriting, multi-column\) AND extraction requires semantic understanding \(linking values to categories\). For clean printed text, Azure Document Intelligence is 10x cheaper \($0.0015 vs $0.005 per page\). However, for semi-structured invoices with line items, GPT-4o Vision at $0.005/page beats Azure \+ post-processing logic that costs $0.008 total.

Journey Context:
Teams default to multimodal LLMs for all document processing, ignoring that traditional OCR is 90% cheaper for clean text. The crossover point is layout complexity. GPT-4o Vision excels at 'visual reasoning'—understanding that a number in the bottom right of a table is a 'total' despite no label. Legacy OCR extracts text then requires expensive business logic to reassemble. Cost analysis: 100k pages/month. Azure DI: $150. GPT-4o Vision: $500. But if 30% need visual reasoning, Azure \+ human review = $600, making Vision cheaper.
