[cost\_intel] Vision API cost explosion with high-resolution screenshots

Resize images to 1024x768 and set detail: 'low' \(fixed 85 tokens\) for UI element detection tasks instead of using detail: 'high' or 'auto'. A 1920x1080 screenshot encodes to ~6000 tokens at high detail, costing $0.015 per image with GPT-4o. Using low detail reduces vision costs by 98% with minimal accuracy loss on text-heavy screenshots.

Journey Context:
Developers assume 'auto' detail mode optimizes cost, but it selects 'high' for most screens >512px, causing massive token bloat. The low-detail mode \(85 tokens\) is sufficient for OCR and element detection on standard DPI screens. The mistake is treating vision tokens like text tokens—image tokens are 1000x larger per unit of information.
