[cost\_intel] How does image resolution silently 10x vision API costs for UI automation?

Pre-process screenshots to 768px-1024px max dimension before sending to GPT-4o Vision or Claude 3; 4K screenshots cost $0.01-0.02 per image vs $0.001 for resized, with negligible OCR accuracy loss for UI elements.

Journey Context:
Developers send native 4K \(3840x2160\) screenshots to vision models for RPA/UI testing, not realizing tokenization. GPT-4o Vision uses a tile-based system: images are scaled to fit in 512px or 2048px tiles depending on detail level. A 4K image at high detail uses 32\+ tiles \(costing ~$0.015/image\). At low detail \(512px\), it's cheaper but misses small UI elements. Claude 3 uses a different system: images are converted to tokens based on dimensions, with 800px shortest side being a breakpoint. Pre-processing to 1024px using PIL/bimg preserves text readability \(OCR\) while cutting costs 10x. Critical: buttons/icons remain legible at 1024px; 4K is overkill for element detection.
