[cost\_intel] Vision token economics for UI automation and video processing

Use GPT-4o's low-resolution vision mode which costs eighty-five tokens per image instead of high-resolution mode for UI element detection and form reading. Low-resolution mode processes a 512 by 512 pixel thumbnail while high-resolution mode costs one hundred seventy tokens base plus eighty-five tokens per 512 by 512 pixel tile. A 1080p screenshot in high-resolution mode costs approximately eleven hundred tokens or zero point zero zero five five dollars versus eighty-five tokens or zero point zero zero zero four two five dollars in low-resolution mode. For button detection, text field location, and OCR of standard web interfaces, low-resolution achieves ninety-five percent accuracy versus ninety-eight percent for high-resolution. Only use high-resolution for text smaller than eight point font or dense data dashboards. Never process video at full thirty frames per second: extract keyframes via frame differencing or OCR pre-filtering to reduce thirty frames per second which costs thirty-three thousand tokens per second or one hundred sixty-five dollars per minute to one frame per second which costs one point one thousand tokens per second or five point fifty dollars per minute.

Journey Context:
Engineers assume higher resolution equals better accuracy for UI automation, but GPT-4o's low-resolution mode uses a 512 by 512 thumbnail that preserves text readability for standard web user interfaces. The high-resolution mode tiles the image into 512 by 512 pixel patches, costing one hundred seventy tokens per tile. A 1920 by 1080 image equals four tiles in a two by two grid plus one hundred seventy base tokens, totaling eight hundred fifty tokens versus eighty-five tokens in low-resolution mode, representing a tenfold difference. Accuracy drops are minimal for button and text detection because user interface elements are relatively large. The significant cost trap involves video processing where one minute of screen recording at thirty frames per second equals one thousand eight hundred frames multiplied by eighty-five tokens, equaling one hundred fifty-three thousand tokens or seven dollars and sixty-five cents even in low-resolution mode. The solution involves using frame differencing or scene change detection to process only ten to twenty keyframes per minute.
