[cost\_intel] GPT-4o Vision high-res image cost explosion

Pre-resize images to 512px on short edge before API call; costs scale by 512x512 tiles \(4x cost for 1024x1024\)

Journey Context:
Vision pricing is per 512x512 tile, not linear. A 1024x1024 image consumes 4 tiles \(2x2\), costing 4x tokens vs 512x512. A 1920x1080 screenshot costs 8 tiles. Teams upload 4K screenshots for 'better OCR' but pay 16x-64x more for marginal accuracy gains on text. Resize to 512px short edge maintains OCR quality while cutting costs 75-90%.
