[cost\_intel] OpenAI vision high-detail mode consumes 7-10x tokens compared to low-detail for large images

Pre-resize images to 512px on the shortest side before sending and explicitly set 'detail: low' unless OCR of fine print is required.

Journey Context:
GPT-4o charges 85 tokens for low-detail images regardless of size. For high-detail, it tiles the image into 512x512 squares. A 2048x4096 image becomes 8-16 tiles, costing 85 \+ \(tiles \* 170\) tokens—easily 1300\+ tokens vs 85. Developers often send high-res screenshots without resizing, assuming the API handles optimization. It doesn't; it faithfully processes every pixel. The alternative of always using low detail loses information. The correct pattern is resizing client-side to just above 512px if high detail is needed, or below 512px to force low-detail pricing.
