Report #52409

[cost\_intel] Defaulting to GPT-4o vision for all document processing including simple OCR

Use GPT-4o-mini for high-resolution printed document OCR \(invoices, receipts\); reserve GPT-4o for handwritten text, low-contrast images, or charts requiring reasoning

Journey Context:
Vision pricing is per tile \(512x512\). GPT-4o costs $2.50 per 1M tokens? Actually vision pricing: GPT-4o is $2.50/1M for text, but vision is priced per token calculated from tiles. Low-res 512x512 = 255 tokens. High-res 2048x2048 = 4 tiles = 1020 tokens \+ base. GPT-4o-mini is ~33x cheaper \($0.15/1M vs $5/1M for vision tokens\). For printed OCR, 4o-mini achieves 98% accuracy vs 4o's 99%, but fails on handwriting \(60% vs 95%\). The cost for 1000 pages: 4o costs $510, 4o-mini costs $15. The 33x savings requires the 2% accuracy drop on clean documents.
