[cost\_intel] Using high-resolution vision models for all document OCR tasks regardless of text type

For printed text OCR \(receipts, invoices, forms\), use GPT-4o-mini-vision at approximately $0.15 per 1MP image instead of Claude 3.5 Sonnet at $3.75 per 1MP \(25x savings\). Quality is identical for printed text, but Sonnet is required for handwriting or complex layouts. The cost cliff occurs at handwriting: mini drops to 70% accuracy where Sonnet maintains 95%.

Journey Context:
Teams often assume 'vision is vision' and use the best model for all image inputs. However, OCR of clean printed text is a solved task that even small vision models handle perfectly. The 25x price difference between GPT-4o-mini and Claude 3.5 Sonnet for vision is justified only when the image contains handwriting, complex tables, or requires spatial reasoning about layout. The signature of wrong model choice: when processing 10,000 receipt images, using Sonnet costs $3,750 vs mini at $150, with identical extraction accuracy. For handwritten forms, mini hallucinates numbers, justifying Sonnet. Common error: not resizing images before sending; both charge per pixel, so sending 4K images of receipts wastes money on over-resolution for OCR.
