[cost\_intel] Why is my GPT-4o vision API bill 100x higher than expected for document processing?

Force 'detail: low' parameter for OCR/document scanning tasks where text is legible at 512px; reduces vision cost from $0.108 to $0.0013 per high-res image \(85x savings\) with minimal accuracy loss on printed text.

Journey Context:
GPT-4o vision pricing has 'low' vs 'high' detail mode. High detail splits images into 512x512 tiles at $0.005 per tile \(approx\). A 4K image \(3840x2160\) = ~32 tiles = $0.16 per image. Low detail resizes to 512px wide and costs a flat ~$0.001275 per image. For document OCR \(receipts, forms\), low detail is often sufficient because the text is large and high contrast. Teams using default 'auto' mode get high detail for any image >512px, exploding costs when processing thousands of documents. The 85x cost difference is real and impactful at scale \(1M images = $1,275 vs $108,000\).
