[cost\_intel] When does high-detail vision mode silently 10x image input costs?

Set "detail": "low" for OCR on printed text and diagrams; "high" detail processes 4K images at 2048x2048 tiles costing 765 tokens/tile vs 65 tokens for "low", creating 10x cost for minimal accuracy gain on clean text.

Journey Context:
OpenAI's vision model calculates tokens based on tiles. "Low" detail uses a single 512x512 thumbnail \(65 tokens\). "High" detail resizes to 2048x2048 then tiles into 768x768 patches \(each 255 tokens after base\). A 1920x1080 image becomes 4 tiles \+ base = ~1100 tokens in high mode vs 65 in low. For dense text OCR, high detail captures font subtleties, but for standard print, low detail achieves 98% OCR accuracy at 1/10th cost. The trap is defaulting to "auto" which selects high for images >512px, silently exploding costs in document processing pipelines.
