Report #101365

[cost\_intel] Sending screenshots to a vision model costs far more than expected

Default to detail: 'low' \(fixed ~85 tokens\) for UI classification, icon recognition, layout, and color tasks; use detail: 'high' only when fine text or small spatial details matter; pre-resize images to the smallest useful resolution before sending.

Journey Context:
On GPT-4o a 1024x1024 image in high mode costs ~765 tokens \(9x low\), and a 2048x4096 image can hit ~1,105 tokens. The default 'auto' detail usually selects high. In agent loops that repeatedly send screenshots, this silently dominates token spend. Quality degrades predictably in low mode: small text becomes unreadable and precise coordinates fail, but overall scene understanding remains high.
