[cost\_intel] GPT-4V vision costs scale with image detail setting and tile count in non-obvious ways that 10x cost for 'high res'

Calculate image tiles pre-upload: tiles = ceil\(width/512\) \* ceil\(height/512\); if tiles > 4 and text is primary, downscale to 1024px max dimension or use 'low' detail

Journey Context:
OpenAI vision pricing uses 'tiles' of 512x512 pixels. A 2048x4096 image in 'high' detail mode uses 8 tiles \(4 wide x 2 tall\), billed at 170 tokens per tile = 1,360 tokens just for the image. The same image in 'low' detail \(single 512x512 thumbnail view\) costs 85 tokens. Agents often default to 'high' for all images, burning 16x tokens on diagrams where text is readable at low resolution. Critical: resizing to 1024x1024 before upload forces max 4 tiles \(2x2\), cutting cost by 50% vs 2048x2048 \(4x4=16 tiles\) with minimal OCR quality loss.
