[cost\_intel] GPT-4o vision vs GPT-4o mini for document OCR

Use GPT-4o mini for high-resolution document OCR \(text extraction from images\) at 1/20th cost; GPT-4o only necessary for charts, diagrams, or spatial reasoning \(reading tables with merged cells\). Mini achieves 99% character accuracy on printed text vs 99.5% for 4o—indistinguishable for data entry pipelines.

Journey Context:
Teams processing PDFs or scanned documents automatically choose GPT-4o for 'vision tasks,' but mini's OCR capabilities are nearly identical for text-heavy inputs. The differentiator is structured understanding: 4o correctly interprets complex tables, flowcharts, and handwritten notes with context, while mini extracts raw text serially. For invoice processing or document digitization pipelines with >1M pages/month, switching to mini reduces vision costs from $0.005 to $0.000255 per image \(800x600\), saving $4,745 per million pages with negligible accuracy loss on typed text.
