Report #57312

[cost\_intel] Vision API detail:high mode costs 9x more than detail:low on 1080p images due to tile-based pricing

Force detail:low for images >2MP unless performing fine text OCR; pre-resize images to 512px on the shortest side before sending to avoid automatic high-detail tiling

Journey Context:
OpenAI's vision pricing uses 512x512px tiles. detail:low = 1 tile \(85 base tokens\). detail:high = up to 2048x2048px = 16 tiles \(170 tokens per tile \+ 85 base\). A 1920x1080 image \(2MP\) triggers 4 tiles in high detail = 765 tokens vs 85 in low—a 9x difference. Many developers pass detail:high by default assuming it's necessary for 'good' results, but for UI screenshots, charts, and general photos, low detail is visually identical and 9x cheaper. The cost trap is automatic: if you don't specify detail:low, the API may default to high for images >512px depending on the model version.
