Report #76739

[cost\_intel] How much does 'high resolution' vision mode actually cost compared to low-res for document OCR?

Use low-res \(512x512 single tile\) for standard OCR of 10pt\+ font; only enable high-res \(>512px\) when reading text <8pt font or dense tables. High-res costs 5-10x more \(up to $0.0075 per image vs $0.00085 for low-res on GPT-4o\).

Journey Context:
Vision pricing is per 512x512 tile. Low-res mode fits the whole image in one tile regardless of source resolution \(server-side downscale\). High-res splits into multiple tiles \(e.g., 2048x2048 = 16 tiles\). For standard printed documents \(12pt font\), low-res achieves 99% OCR accuracy on GPT-4o. High-res is only needed for fine print, handwriting, or when spatial precision matters \(e.g., reading coordinates from a chart\). Always specify 'low' detail parameter explicitly; some SDKs default to 'high'. For PDF processing, convert to 150 DPI images rather than 300 DPI to stay within low-res tile limits.
